Discussion about Primecoin and its infra. Primecoin is a very innovative cryptocurrency, being the 1st non Hash-Cash PoW crypto, naturally scarce (not artificially), with very fast confirmations (1min), elastic readjusting reward & a useful mining (byproducts are primes). Primecoin is sustainable (miners are guaranteed to have revenues), and decentralized (ASIC/FPGA are not particularly advantaged). Sidechain for decentralized data applications (e.g. Storj) currently in development.
Primecoin is an innovative cryptocurrency, a form of digital currency secured by cryptography and issued through a decentralized mining market. Derived from Satoshi Nakamoto's Bitcoin, Primecoin introduces an unique form of proof-of-work based on searching for prime numbers.
Ok so I want the wise internet to set me straight...
Bitcoins are not legal tender under "any" country in the world. However just like the shells of native american indians they are allowed by current standards as a means of paying for goods and services. I am assuming that the first bitcoins mined (Wikipedia says it was 50 in the first blockchain) had no "value". I am then assuming that as soon as people caught up with the idea and miners begain selling bitcoins as a service (USD to BTC) the value became established. So what is the " value"? Is it really $350? Or is it $0? I believe that a bitcoin in and of itself is nothing more then a share or stock. Why? Bitcoins a very volital and the price changes each second on a exchange. They have link to currency only so much as the ability to sell it for USD. More bitcoins can be made by mining them but unless you pay dearly for the equipment, have free electricity, and a buyer you won't make any money. Now read this... Stocks very volital and the price changes by the second on an exchange. They have a like to currency only so much as the ability to sell it for USD. More shares can be made by issuing them but unless you own a company, have a revenue, and a buyer you won't make money, You see they are the same thing, right? I'm asking the internet for an explanation for this, is it possible that we all own a share of the total paid in value of the coins? What do you think?
Wikipedia should use the "visitors bitcoin mining" thing to support the site
You know how Pirate Bay and some other sites made a thing that the visitor would mine bitcoins while using the site? Wikipedia could make big bucks with this and I think no-one would mind helping wikipedia like that.
You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments. It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
Accountable - The public ledger is transparent, all transactions are seen by everyone.
Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works. You can even run a node on a Raspberry Pi.
Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
Low fee scaling - On chain transaction fees depend on network demand and how much priority you wish to assign to the transaction. Most wallets calculate on chain fees automatically but you can view current fees here and mempool activity here. On chain fees may rise occasionally due to network demand, however instant micropayments that do not require confirmations are happening via the Lightning Network, a second layer scaling solution currently rolling out on the Bitcoin mainnet.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply memorizing a string of words for wallet recovery (while cool this method is generally not recommended due to potential for insecure key generation by inexperienced users. Hardware wallets are the preferred method for new users due to ease of use and additional security).
Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage. Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, then you will need to create your own wallet and keep it secure. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor, Ledger or ColdCard is recommended. Alternatively there are many software wallet options to choose from here depending on your use case.
If you prefer to let third party "Bitcoin banks" manage your coins, try Gemini but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email! 2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".
Where can I spend bitcoins?
Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out. If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.
Just like any other form of money, you can also earn bitcoins by being paid to do a job.
You can also earn bitcoins by participating as a market maker on JoinMarket by allowing users to perform CoinJoin transactions with your bitcoins for a small fee (requires you to already have some bitcoins.
The following is a short list of ongoing projects that might be worth taking a look at if you are interested in current development in the bitcoin space.
One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
one bitcoin is equal to 100 million satoshis
1,000 per bitcoin
used as default unit in recent Electrum wallet releases
1,000,000 per bitcoin
colloquial "slang" term for microbitcoin (μBTC)
100,000,000 per bitcoin
smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Dragonchain Great Reddit Scaling Bake-Off Public Proposal
Dragonchain Public Proposal TL;DR:
Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and postsper Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625. Watch Joe walk through the entire proposal and answer questions onYouTube. This proposal is also available on the Dragonchain blog.
Hello Reddit and Ethereum community!
I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale. For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube. We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.
Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.
Response and PoC
In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.
A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks. 24 hours in 4 minutes (YouTube): 24 hours in 4 minutes The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period. Tooling to reproduce our demo is available here: https://github.com/dragonchain/spirit-bomb
Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.
Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired. Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.
An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity. TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block. TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.
Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain. With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times. We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment. Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.
Flexibility in Scaling
Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems. We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
LBRY - To allow users to deploy content natively to LBRY
MakerDAO to allow users to lend small amounts backed by their Reddit community points.
STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.
Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction. Dragonchain Fees Table
How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node. Getting started is easy...
Download Dragonchain’s dctl
Input three commands into a terminal
Build an image
More information can be found in our Get started documents.
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain. Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain. After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks. Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.
Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.
Costs and resources
Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD. For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments. Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.
This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users. Over a 5 day period, your scaling PoC should be able to handle: *100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes. Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum. Reddit Scaling on Ethereum
Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
Operational on-premises capabilities
Operational deployment to any datacenter
Over 700 independent Community Verification Nodes with proof of ownership
Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)
Usability Scaling solutions should have a simple end user experience.
Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node. Examples:
Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.
Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users. All of Reddit's Transactions on Blockchain (month) Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees. Reddit Internal Token Transaction Fees Reddit Ethereum Token Transaction Fees When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
In a combination of the above, customers could cover aggregated fees.
Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.
Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here. Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here. In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here. A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.
Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.
Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.
Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible APIs should be well documented and stable
Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected. Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.
Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.
Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR. Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.
Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.
Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.
Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw
Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.
A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.
Bonus points Public, third-party implementation review available or in progress
Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.
Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.
One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).
Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!
Disney Releases Blockchain Platform as Open Source
The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group. https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html
In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney. Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
Obtain VP support and approval for the release
Verify ownership of the software to be released
Verify that no proprietary content would be released
Convince the organization that there was a value to the open source community
Convince the organization that there was a value to Disney
Offer the plan for ongoing maintenance of the project outside of Disney
Itemize competing projects
Verify no conflict of interest
Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
Obtain legal approval
Approval from corporate, parks, and other business units
Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
Trademark searches conducted for the selected name Dragonchain
Obtain IT security approval
Manual review of OSS components conducted
OWASP Dependency and Vulnerability Check Conducted
Obtain technical (software) approval
Offer management, process, and financial plans for the maintenance of the project.
Meet list of items to be addressed before release
Remove all Disney project references and scripts
Create a public distribution list for email communications
Remove Roets’ direct and internal contact information
Create public Slack channel and move from Disney slack channels
Create proper labels for issue tracking
Rename internal private Github repository
Add informative description to Github page
Expand README.md with more specific information
Add information beyond current “Blockchains are Magic”
Add getting started sections and info on cloning/forking the project
Add installation details
Add uninstall process
Add unit, functional, and integration test information
Detail how to contribute and get involved
Describe the git workflow that the project will use
Move to public, non-Disney git repository (Github or Bitbucket)
Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney. The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Why Osana takes so long? (Programmer's point of view on current situation)
I decided to write a comment about «Why Osana takes so long?» somewhere and what can be done to shorten this time. It turned into a long essay. Here's TL;DR of it:
The cost of never paying down this technical debt is clear; eventually the cost to deliver functionality will become so slow that it is easy for a well-designed competitive software product to overtake the badly-designed software in terms of features. In my experience, badly designed software can also lead to a more stressed engineering workforce, in turn leading higher staff churn (which in turn affects costs and productivity when delivering features). Additionally, due to the complexity in a given codebase, the ability to accurately estimate work will also disappear. Junade Ali, Mastering PHP Design Patterns (2016)
Longer version: I am not sure if people here wanted an explanation from a real developer who works with C and with relatively large projects, but I am going to do it nonetheless. I am not much interested in Yandere Simulator nor in this genre in general, but this particular development has a lot to learn from for any fellow programmers and software engineers to ensure that they'll never end up in Alex's situation, especially considering that he is definitely not the first one to got himself knee-deep in the development hell (do you remember Star Citizen?) and he is definitely not the last one. On the one hand, people see that Alex works incredibly slowly, equivalent of, like, one hour per day, comparing it with, say, Papers, Please, the game that was developed in nine months from start to finish by one guy. On the other hand, Alex himself most likely thinks that he works until complete exhaustion each day. In fact, I highly suspect that both those sentences are correct! Because of the mistakes made during early development stages, which are highly unlikely to be fixed due to the pressure put on the developer right now and due to his overall approach to coding, cost to add any relatively large feature (e.g. Osana) can be pretty much comparable to the cost of creating a fan game from start to finish. Trust me, I've seen his leaked source code (don't tell anybody about that) and I know what I am talking about. The largest problem in Yandere Simulator right now is its super slow development. So, without further ado, let's talk about how «implementing the low hanging fruit» crippled the development and, more importantly, what would have been an ideal course of action from my point of view to get out. I'll try to explain things in the easiest terms possible.
else if's and lack any sort of refactoring in general
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away. Antoine de Saint-Exupéry
This is why refactoring — activity of rewriting your old code so it does the same thing, but does it quicker, in a more generic way, in less lines or simpler — is so powerful. In my experience, you can only keep one module/class/whatever in your brain if it does not exceed ~1000 lines, maybe ~1500. Splitting 17000-line-long class into smaller classes probably won't improve performance at all, but it will make working with parts of this class way easier. Is it too late now to start refactoring? Of course NO: better late than never.
If you think that you wrote this code, so you'll always easily remember it, I have some bad news for you: you won't. In my experience, one week and that's it. That's why comments are so crucial. It is not necessary to put a ton of comments everywhere, but just a general idea will help you out in the future. Even if you think that It Just Works™ and you'll never ever need to fix it. Time spent to write and debug one line of code almost always exceeds time to write one comment in large-scale projects. Moreover, the best code is the code that is self-evident. In the example above, what the hell does (float) 6 mean? Why not wrap it around into the constant with a good, self-descriptive name? Again, it won't affect performance, since C# compiler is smart enough to silently remove this constant from the real code and place its value into the method invocation directly. Such constants are here for you. I rewrote my code above a little bit to illustrate this. With those comments, you don't have to remember your code at all, since its functionality is outlined in two tiny lines of comments above it. Moreover, even a person with zero knowledge in programming will figure out the purpose of this code. It took me less than half a minute to write those comments, but it'll probably save me quite a lot of time of figuring out «what was I thinking back then» one day. Is it too late now to start adding comments? Again, of course NO. Don't be lazy and redirect all your typing from «debunk» page (which pretty much does the opposite of debunking, but who am I to judge you here?) into some useful comments.
This is often neglected, but consider the following. You wrote some code, you ran your game, you saw a new bug. Was it introduced right now? Is it a problem in your older code which has shown up just because you have never actually used it until now? Where should you search for it? You have no idea, and you have one painful debugging session ahead. Just imagine how easier it would be if you've had some routines which automatically execute after each build and check that environment is still sane and nothing broke on a fundamental level. This is called unit testing, and yes, unit tests won't be able to catch all your bugs, but even getting 20% of bugs identified at the earlier stage is a huge boon to development speed. Is it too late now to start adding unit tests? Kinda YES and NO at the same time. Unit testing works best if it covers the majority of project's code. On the other side, a journey of a thousand miles begins with a single step. If you decide to start refactoring your code, writing a unit test before refactoring will help you to prove to yourself that you have not broken anything without the need of running the game at all.
This is basically pretty self-explanatory. You set this thing once, you forget about it. Static code analyzer is another «free estate» to speed up the development process by finding tiny little errors, mostly silly typos (do you think that you are good enough in finding them? Well, good luck catching x << 4; in place of x <<= 4; buried deep in C code by eye!). Again, this is not a silver bullet, it is another tool which will help you out with debugging a little bit along with the debugger, unit tests and other things. You need every little bit of help here. Is it too late now to hook up static code analyzer? Obviously NO.
Say, you want to build Osana, but then you decided to implement some feature, e.g. Snap Mode. By doing this you have maybe made your game a little bit better, but what you have just essentially done is complicated your life, because now you should also write Osana code for Snap Mode. The way game architecture is done right now, easter eggs code is deeply interleaved with game logic, which leads to code «spaghettifying», which in turn slows down the addition of new features, because one has to consider how this feature would work alongside each and every old feature and easter egg. Even if it is just gazing over one line per easter egg, it adds up to the mess, slowly but surely. A lot of people mention that developer should have been doing it in object-oritented way. However, there is no silver bullet in programming. It does not matter that much if you are doing it object-oriented way or usual procedural way; you can theoretically write, say, AI routines on functional (e.g. LISP)) or even logical language if you are brave enough (e.g. Prolog). You can even invent your own tiny programming language! The only thing that matters is code quality and avoiding the so-called shotgun surgery situation, which plagues Yandere Simulator from top to bottom right now. Is there a way of adding a new feature without interfering with your older code (e.g. by creating a child class which will encapsulate all the things you need, for example)? Go for it, this feature is basically «free» for you. Otherwise you'd better think twice before doing this, because you are going into the «technical debt» territory, borrowing your time from the future by saying «I'll maybe optimize it later» and «a thousand more lines probably won't slow me down in the future that much, right?». Technical debt will incur interest on its own that you'll have to pay. Basically, the entire situation around Osana right now is just a huge tale about how just «interest» incurred by technical debt can control the entire project, like the tail wiggling the dog. I won't elaborate here further, since it'll take me an even larger post to fully describe what's wrong about Yandere Simulator's code architecture. Is it too late to rebuild code architecture? Sadly, YES, although it should be possible to split Student class into descendants by using hooks for individual students. However, code architecture can be improved by a vast margin if you start removing easter eggs and features like Snap Mode that currently bloat Yandere Simulator. I know it is going to be painful, but it is the only way to improve code quality here and now. This will simplify the code, and this will make it easier for you to add the «real» features, like Osana or whatever you'd like to accomplish. If you'll ever want them back, you can track them down in Git history and re-implement them one by one, hopefully without performing the shotgun surgery this time.
Again, I won't be talking about the performance, since you can debug your game on 20 FPS as well as on 60 FPS, but this is a very different story. Yandere Simulator is huge. Once you fixed a bug, you want to test it, right? And your workflow right now probably looks like this:
Fix the code (unavoidable time loss)
Rebuild the project (can take a loooong time)
Load your game (can take a loooong time)
Test it (unavoidable time loss, unless another bug has popped up via unit testing, code analyzer etc.)
And you can fix it. For instance, I know that Yandere Simulator makes all the students' photos during loading. Why should that be done there? Why not either move it to project building stage by adding build hook so Unity does that for you during full project rebuild, or, even better, why not disable it completely or replace with «PLACEHOLDER» text for debug builds? Each second spent watching the loading screen will be rightfully interpreted as «son is not coding» by the community. Is it too late to reduce loading times? Hell NO.
Or any other continuous integration tool. «Rebuild a project» can take a long time too, and what can we do about that? Let me give you an idea. Buy a new PC. Get a 32-core Threadripper, 32 GB of fastest RAM you can afford and a cool motherboard which would support all of that (of course, Ryzen/i5/Celeron/i386/Raspberry Pi is fine too, but the faster, the better). The rest is not necessary, e.g. a barely functional second hand video card burned out by bitcoin mining is fine. You set up another PC in your room. You connect it to your network. You set up ramdisk to speed things up even more. You properly set up Jenkins) on this PC. From now on, Jenkins cares about the rest: tracking your Git repository, (re)building process, large and time-consuming unit tests, invoking static code analyzer, profiling, generating reports and whatever else you can and want to hook up. More importantly, you can fix another bug while Jenkins is rebuilding the project for the previous one et cetera. In general, continuous integration is a great technology to quickly track down errors that were introduced in previous versions, attempting to avoid those kinds of bug hunting sessions. I am highly unsure if continuous integration is needed for 10000-20000 source lines long projects, but things can be different as soon as we step into the 100k+ territory, and Yandere Simulator by now has approximately 150k+ source lines of code. I think that probably continuous integration might be well worth it for Yandere Simulator. Is it too late to add continuous integration?NO, albeit it is going to take some time and skills to set up.
Stop caring about the criticism
Stop comparing Alex to Scott Cawton. IMO Alex is very similar to the person known as SgtMarkIV, the developer of Brutal Doom, who is also a notorious edgelord who, for example, also once told somebody to kill himself, just like… However, being a horrible person, SgtMarkIV does his job. He simply does not care much about public opinion. That's the difference.
[Spoilers S7] Here's what we know about the state of Earth before the bombs
Here's a compiled list of what Earth was like pre-apocalypse using details from the show. Jason Rothenberg has said if the prequel gets greenlit, he wants to implement a lot of flashbacks LOST style. These flashbacks may include references to the following:
In Monty's video message he said: "After sucking the Earth dry of oil, they went looking for another planet to tap." [Episode 5x13]
This is presumably why Eligius I (unmanned), II (manned), and IV (prison labor) were sent to asteroids to mine for hythylodium, an incredibly efficient energy source. Hythylodium was used to power the Eligius III and IV missions. [Episode 5x03]
Other energy alternatives are used, such as solar energy (the field of solar panels Jaha and Murphy see in 2x14). And in 6x04, Ryker tells Raven the propellant they use for the motorcycles is "ethanol distilled from Earth corn."
During Josephine's flashback in Boston, a man walks into a diner holding a mask, brushing dust off his shoulders. Josephine's friend also says "It's really dusty outside." You can see multiple people in the diner wearing masks around their neck. [Episode 6x07]
During Josephine's flashback, the guy that commits suicide mentions that she posted about going to a water-rationing protest. [Episode 6x07]
Gabriel says his mother's water was cut off in Colombia so the rich could water their lawns. [Episode 7x10]
On Callie's TV, a headline says "Yosemite National Park Burns". [Screenshot] Another headline says: "Deadly Heat Wave". [Screenshot] You can also hear the newscaster mention "above 110 degrees." [Episode 7x08]
On Callie's TV, a headline says "Russian Ankovirus Spreads". [Screenshot] The newscaster mentions the US has declared a public health alert. [Episode 7x08]
Becca says ALIE intends to kill 6.5 billion people to solve overpopulation. She's not trying to kill 100% of the population, so 6.5 billion is not the total population count. [Episode 3x16]
On Callie's TV, a headline says "World's 11 Billionth Child Born". [Screenshot][Episode 7x08]
This is abundant when we look at the technologies developed by just Becca and Eligius, such as large space ships, cryopods, sonic drills, brain chips, ALIE, nightblood, etc.
We also see hologram technology. In 2x16, Jaha first meets ALIE in hologram form. In 7x08, it's used as a telecommunication device when Callie speaks to her father and brother.
On Callie's TV, we see a headline "first human brain transplant successfully performed in Bangalore". [Screenshot] Another headline says "Dubai's Alpha Centauri Group debuts first orbital hotel". [Screenshot][Episode 7x08]
Becca Franko, The Tech Celebrity
She went to Harvard when she was 10 years old. [Episode 7x08]
She started making tech for Eligius at 18 years old. [Episode 6x01]
She owned her own company. We don't know the name of it but we do know it's corporate logo is an infinity sign and its motto is "Seek Higher Things". [Episode 3x07]
People idolized her. The newscaster on Callie's TV said she had "legions of devotees". In 6x07, Josephine had a magazine with Becca featured on the cover. In 7x08, Reese said "Don't mind my sister. She once dressed as you for Halloween."
She owned her own television network. The channel that Callie was watching on her TV has the infinity sign as its network logo. [Screenshot] The newscaster said "The reclusive billionaire and owner of this network made her last public appearance". [Episode 7x08]
On Callie's TV, a headline says "Stock Market Headed For A ..." and it's cut off. [Screenshot] There's most likely a recession going on and stock markets are crashing. You can also see bitcoin (BTC) is worth 4563.44 (half of what it is today). [Screenshot] Also, on top of the pandemic, huge advancements in AI and technology are most likely disrupting businesses and employment as well. [Episode 7x08]
On Callie's TV, we see a headline "Wyoming joins 32 other states in legalizing the recreational use of psilocybin mushrooms". Shrooms. [Screenshot][Episode 7x08]
Battles in U.S. Cities
The Battle of San Francisco was an armed conflict that Shaw recalls watching on TV as a child. During Diyoza's time in the military, she was one of the soldiers helping the evacuation of thousands of refugees. [Episode 5x07]
Resistance Groups & Terrorism
The United Liberation Army (ULA), was a terrorist group dedicated to fighting against the corrupt government that Diyoza became a part of after the military. The ULA was involved in many terror attacks, including an attack on the 4th of July (which they took credit for) that killed 80 civilians in a plane bombing, and a suspected metro suicide bombing in Washington D.C., killing 19 civilians. [Screenshot][Episode 5x04]
Corrupt U.S. Government
Diyoza says to Clarke "When the fascist government tried to take my home, I wanted blood too." [Episode 5x03]
When Reese mentions Callie dropping out of MIT, she says "Refusing to take part in fascistic regimes is my thing." [Episode 7x08]
On Callie's TV, the newscaster says "... when riot police, on orders from the Wallace Administration, moved in to clear the extreme environmental group known as The Tree Crew." [Episode 7x08]
Callie: "Extreme? What a joke. We were there peacefully. They're the extreme ones."
Lucy: "Don't they know they're defending a system that hurts people like them?"
Callie: People want to believe their leaders are telling the truth, which is why we need to get back there and continue exposing their lies.
The US president at the time of the bombs was a Wallace. In Season 2, Dante says "I love you Cage, and there's been a Wallace in this office since the bombs but if I find out that you're lying there won't be one after me". So most likely the Wallace administration and their family was corrupt. They easily decided to do away with democracy in order to have complete control in Mount Weather. [Episode 2x06]
Russell says to Diyoza in 6x03 "Your face is in our history books next to Hitler and Bin Laden". Eligius took part in federal prison labor, so most likely they had close ties with the government. Fascist governments like to vilify their opponents through propaganda. Even though Diyoza was indeed causing violence, she was probably also used as a scapegoat by the government since she was against them. Even Gabriel said in 7x04, "She was a freedom fighter, not a terrorist".
On Callie's TV, the newscaster says "The 11 billionth baby was born in the Wayne County Internment Camp". Internment camps/concentration camps are "camps where persons are confined, usually without hearings and typically under harsh conditions, often as a result of their membership in a group which the government has identified as dangerous or undesirable." [Source]
On Callie's TV, a headline says "Congress's negotiations on economic relief funds at an impasse amidst violent riots ..." [Screenshot]
Cult Mentality & Conspiracy Theories
In 7x10, Gabriel says to Bill Cadogan "Earth was pretty terrible. But it's good for the cult business, am I right?"
According to this article, Bill grew up in poverty. And Jaha mentioned in 4x03 that Bill's father beat him frequently. Bill, a millennial, says in 7x10 that his first job was flipping burgers, dreaming of the day he'd escape. "There must be more to life than politics, the dying ecosystem, the memes." In times of economic hardship and social upheaval, it's easy for people to latch onto certain beliefs.
Callie says Bill's a vulture capitalist who "traded his precious credibility to become a prophet of doom". She also called him a cultural artifact thief. He found and stole the Anomaly stone from Machu Picchu and in 2042, he started studying it. [Episode 7x08]
It's unknown when Bill founded the Second Dawn, but we know a news article was written about them in 2042, saying that only those with lots of money could "unlock the twelve seals" since it required payments of over $10 million to the cult. [Episode 4x03]
That's what I got. If you spotted anything else from the show, feel free to share! :) Edit: Thanks everyone for the kind words and the awards! Also, thanks to clwrutgers for asking me to make this list.
Eth 2.0 vs Polkadot and other musings by a fundamental investor
Spent about two hours on this post and I decided it would help the community if I made it more visible. Comment was made as a response to this
I’m trying to avoid falling into a maximalist mindset over time. This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech. Can someone help me see the downsides of diversifying into DOTs? I know Polkadot is more centralized, VC backed, and generally against our ethos here. On chain governance might introduce some unknown risks. What else am I missing? I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
What else am I missing?
The upsides. Most of the guys responding to you here are full Eth maxis who drank the Parity is bad koolaid. They are married to their investment and basically emotional / tribal in an area where you should have a cool head. Sure, you might get more upvotes on Reddit if you do and say what the crowd wants, but do you want upvotes and fleeting validation or do you want returns on your investment? Do you want to be these guys or do you want to be the shareholder making bank off of those guys? Disclaimer: I'm both an Eth whale and a Dot whale, and have been in crypto for close to a decade now. I originally bought ether sub $10 after researching it for at least a thousand hours. Rode to $1500 and down to $60. Iron hands - my intent has always been to reconsider my Eth position after proof of stake is out. I invested in the 2017 Dot public sale with the plan of flipping profits back to Eth but keeping Dots looks like the right short and long term play now. I am not a trader, I just take a deep tech dive every couple of years and invest in fundamentals. Now as for your concerns:
I know Polkadot is more centralized
The sad truth is that the market doesn't really care about this. At all. There is no real statistic to show at what point a coin is "decentralized" or "too centralized". For example, bitcoin has been completely taken over by Chinese mining farms for about five years now. Last I checked, they control above 85% of the hashing power, they just spread it among different mining pools to make it look decentralized. They have had the ability to fake or block transactions for all this time but it has never been in their best interest to do so: messing with bitcoin in that way would crash its price, therefore their bitcoin holdings, their mining equipment, and their company stock (some of them worth billions) would evaporate. So they won't do it due to economics, but not because they can't. That is the major point I want to get across; originally Bitcoin couldn't be messed with because it was decentralized, but now Bitcoin is centralized but it's still not messed with due to economics. It is basically ChinaCoin at this point, but the market doesn't care, and it still enjoys over 50% of the total crypto market cap. So how does this relate to Polkadot? Well fortunately most chains - Ethereum included - are working towards proof of stake. This is obviously better for the environment, but it also has a massive benefit for token holders. If a hostile party wanted to take over a proof of stake chain they'd have to buy up a massive share of the network. The moment they force through a malicious transaction a proof of stake blockchain has the option to fork them off. It would be messy for a few days, but by the end of the week the hostile party would have a large amount of now worthless tokens, and the proof of stake community would have moved on to a version of the blockchain where the hostile party's tokens have been slashed to zero. So not only does the market not care about centralization (Bitcoin example), but proof of stake makes token holders even safer. That being said, Polkadot's "centralization" is not that far off to Ethereum. The Web3 foundation kept 30% of the Dots while the Ethereum Foundation kept 17%. There are whales in Polkadot but Ethereum has them too - 40% of all genesis Ether went to 100 wallets, and many suspect that the original Ethereum ICO was sybiled to make it look more popular and decentralized than it really was. But you don't really care about that do you? Neither do I. Whales are a fact of life.
VCs are part of the crypto game now. There is no way to get rid of them, and there is no real reason why you should want to get rid of them. They put their capital at risk (same as you and me) and seek returns on their investment (same as you and me). They are both in Polkadot and Ethereum, and have been for years now. I have no issue with them as long as they don't play around with insider information, but that is another topic. To be honest, I would be worried if VCs did not endorse chains I'm researching, but maybe that's because my investing style isn't chasing hype and buying SUSHI style tokens from anonymous (at the time) developers. That's just playing hot potato. But hey, some people are good at that. As to the amount of wallets that participated in the Polkadot ICO: a little known fact is that more individual wallets participated in Polkadot's ICO than Ethereum's, even though Polkadot never marketed their ICO rounds due to regulatory reasons.
generally against our ethos here
Kool aid. Some guy that works(ed?) at Parity (who employs what, 200+ people?) correctly said that Ethereum is losing its tech lead and that offended the Ethereum hivemind. Oh no. So controversial. I'm so personally hurt by that. Some guy that has been working for free on Ethereum basically forever correctly said that Polkadot is taking the blockchain tech crown. Do we A) Reflect on why he said that? or B) Rally the mob to chase him off?
Also Parity locked their funds (and about 500+ other wallets not owned by them) and proposed a solution to recover them. When the community voted no they backed off and did not fork the chain, even if they had the influence to do so. For some reason this subreddit hates them for that, even if Parity did the 100% moral thing to do. Remember, 500+ other teams or people had their funds locked, so Parity was morally bound to try its best to recover them. Its just lame drama to be honest. Nothing to do with ethos, everything to do with emotional tribalism. Now for the missing upsides (I'll also respond to random fragments scattered in the thread):
This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
A good quick intro to Eth's tech vs Polkadot's tech can be found on this thread, especially this reply. That thread is basically mandatory reading if you care about your investment. Eth 2.0's features will not really kick in for end users until about 2023. That means every dapp (except DeFI, where the fees make sense due to returns and is leading the fee market) who built on Eth's layer 1 are dead for three years. Remember the trading card games... Gods Unchained? How many players do you think are going to buy and sell cards when the transaction fee is worth more than the cards? All that development is now practically worthless until it can migrate to its own shard. This story repeats for hundreds of other dapp teams who's projects are now priced out for three years. So now they either have to migrate to a one of the many unpopulated L2 options (which have their own list of problems and risks, but that's another topic) or they look for another platform, preferably one interoperable with Ethereum. Hence Polkadot's massive growth in developer activity. If you check out https://polkaproject.com/ you'll see 205 projects listed at the time of this post. About a week ago they had 202 listed. That means about one team migrated from another tech stack to build on Polkadot every two days, and trust me, many more will come in when parachains are finally activated, and it will be a complete no brainer when Polkadot 2.0 is released. Another huge upside for Polkadot is the Initial Parachain Offerings. Polkadot's version of ICOs. The biggest difference is that you can vote for parachains using your Dots to bind them to the relay chain, and you get some of the parachain's tokens in exchange. After a certain amount of time you get your Dots back. The tokenomics here are impressive: Dots are locked (reduced supply) instead of sold (sell pressure) and you still earn your staking rewards. There's no risk of scammers running away with your Ether and the governance mechanism allows for the community to defund incompetent devs who did not deliver what was promised.
Wouldn’t an ETH shard on Polkadot gain a bunch of scaling benefits that we won’t see natively for a couple years?
Yes. That is correct. Both Edgeware and Moonbeam are EVM compatible. And if the original dapp teams don't migrate their projects someone else will fork them, exactly like SUSHI did to Uniswap, and how Acala is doing to MakerDao.
Although realistically Ethereum has a 5 yr headstart and devs haven't slowed down at all
Just because it's "EVM Compatible" doesn't mean you can just plug Ethereum into Polkadot or vica versa, it just means they both understand Ethereum bytecode and you can potentially copy/paste contracts from Ethereum to Polkadot, but you'd still need to add a "bridge" between the 2 chains, so it adds additional complexity and extra steps compared to using any of the existing L2 scaling solutions
That only applies of you are thinking from an Eth maximalist perspective. But if you think from Polkadot's side, why would you need to use the bridge back to Ethereum at all? Everything will be seamless, cheaper, and quicker once the ecosystem starts to flourish.
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
They are competitors. Both have their strategies, and both have their strengths (tech vs time on the market) but they are clearly competing in my eyes. Which is a good thing, Apple and Samsung competing in the cell phone market just leads to more innovation for consumers. You can still invest in both if you like. Edit - link to post and the rest of the conversation: https://www.reddit.com/ethfinance/comments/iooew6/daily_general_discussion_september_8_2020/g4h5yyq/ Edit 2 - one day later PolkaProject count is 210. Devs are getting the hint :)
I keep hearing "Deflation before massive inflation"
So what can we do about it? Any ideas are welcome. It has a lot of "what if's"... It depends how tax and law play out with it.Historically speaking:
Commodities and things people use every day become expensive,
Luxury goods fall in value.
Inflation wipes out all savings, there is often a rush to spend money while it has value. "Bank runs" and "Bank Bail in's" where the bank will limit your withdraws to prop up the bank temporarily. Sure here the FDIC may insure it, but its nothing if your money is losing value by the hour and it takes months to get it actually into your hands. And many countries have issues with a person holding cash..."You're automatically a drug dealer! >your money is now drug money! >Asset forfeiture" ...I cant count how many times this happens.
People yell " physical gold and silver!" ... yeah, those do hold value well, however the gov does tax that at 26-30% when sold, and will often ban its use in dire times. ....huge grey / pirate area.
Mining stock is the same in the tax range, and nearly anything you "resell", imposed taxes and royalties can be added leaving you high and dry.
Precious metal holdings have been banned in the past, even here in the USA...aka Government confiscation.
Nationalization of Precious metals mines have happened.
Edit: I now realize there are many ways stocks can play out.
Real Estate will raise in value hugely, However so will the taxes, longer contracts at fixed rates benefits the lendee.
Things that you use, if you can stock or invest in it.
-I stock bulk diesel for my cars while following historical averages to buy cheap.
-Rotating food stock
-Extra maintenance items, including the big things like a roof on your home if its coming time. Not joking I have a spare water heater and backup heating options, along with minor parts and filters to fix them. Same with cars and engines, (spark plugs, filters (all different filters), oil, cheap sensors that usually go bad and are only 4-10$ each, 1-2 extra alternator per vehicle, belts, mowing belts, bearings, grease, ... and I've literally had to use everything on that list and reorder.)
Things that directly pay you back or are insurance. Saving money is making money.
-Security, Locks, Alarms, Cameras, people steal.
A deep freezer for instance can stock food you use and buy on sale.
Solar energy and solar heating supplements energy you use anyways
Rainwater can be collected and used rather than buying from a source.
A cooking gadget vs eating out.
Tools and learning to fix things vs hire.
House insulation.-Better insulative windows, and sealing.
Bidet on toilet (lol serious though...)
Your education can be a huge one, not just for prepping but also in your work.
Things that prevent rot, fire, flood / humidity, or failure. Humidity is a silent killer to many preps. (water sump pumps, dehumidifiers, leak prevention, fire extinguishers / sprinklers, )
Things that last and can be resold on the street if need be. This list can be huge, you have to balance it with liquidity, what you use but can also sell before it goes bad / fails.
Honestly and unpopularly, Things that can avoid tax when the price inflates out of control and you wish to sell. The numbers can be so distorted in both price and taxing of income. Eggs for instance, in many countries from Weimar Republic of Germany to Venezuela, increased 15,000%+, So that $15,000 egg / $150,000 dozen that you sold from your chickens gets taxed in the highest tax bracket? (which can go into the 90% range if rules aren't changed for the massive inflation) Taxes usually try raising during this and many companies flee the country, add robots / machines, or downsize as the result of more taxes making work and jobs even more of an issue. .. honestly history shows the whole thing being a cluster-duck in so many ways. Alternative currencies pop up, actual trades happen and go unreported, crime even shifts when things get too bad, again with Venezuela, I read that criminals were moving to other countries because the people were too poor to even make anything robbing! You can also have a business where you write off so many things that you would use anyways. The numbers get... err... odd, play the game.
It is usually around 10 years of chaos before things start "stabilizing." and even then, so much damage has occured.
This is a serious thing that has happened to once prosperous people / civilizations in the past...don't think you're exempt, especially when the numbers are at historical limits in many countries. Invest in yourself and what you use regularly.
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
Technology and some more:
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
Down the rabbit hole
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here. Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017. Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand. Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”.Scilla design story part 1
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
“Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
Smart contract on a sharded environment and state sharding
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
Business & Partnerships
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
Marketing & Community
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!
Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants
Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants… Bonne découverte. La guerre contre Bitcoin Bitcoin est peut-être le meilleur outil de liberté économique de cette génération, et peut-être depuis plusieurs générations. Malheureusement, Bitcoin a été furieusement étouffé par une guerre civile brutale depuis environ cinq ans maintenant; menée par des ingénieurs sociaux professionnels de certaines des entreprises les plus puissantes de l'espace des médias sociaux. Leur talent dans l'art et la science de la manipulation a permis aux "Bitcoiners" de se battre largement entre eux plutôt que de chercher à créer des modèles commerciaux innovants basés sur les données qui pourraient révolutionner l'économie mondiale via Bitcoin. À la suite de la guerre civile de Bitcoin, trois versions concurrentes de Bitcoin ont vu le jour (BTC, BCH et Bitcoin SV ), mais il en est de même pour environ 3000 autres projets et jetons de « crypto-monnaie » se faisant passer pour des entreprises légitimes - jusqu'à un "exit scam" presque garantie, le fait de disparaitre du jour au lendemain avec tout l'argent des utilisateurs. Le principal bienfaiteur de la guerre civile Bitcoin a été Ethereum: une machine à états mondiale qui permet un déploiement facile de tokens et de contrats intelligents, mais le protocole Ethereum ne peut pas évoluer, et parmis les milliers de projets lancés, seule une poignée pourrait même être présentée comme avoir les ingrédients nécessaires pour devenir des entreprises légitimes. La plupart des autres sont des stratagèmes de Ponzi ou des émissions d'actions illégales - enrichissant les développeurs et escroquant les investisseurs amateurs. C'est dans ce contexte que les défenseurs de BTC et de BCH, les porte-parole d'Ethereum et les altcoiners de tous bords s'alignent pour attaquer sans cesse le protocole Bitcoin préservé uniquement par le réseau BSV. Une industrie composée presque entièrement de criminels, de fraudes et d'arnaqueurs s'est unie contre BSV citant (et c'est là l'ironie) une prétendue fraude et arnaque présumée qui est l'existence même de BSV. Nous devons nous demander pourquoi ? Quel est le différenciateur clé de BSV? Pourquoi tous les arnaqueurs se sont-ils unis contre lui? Je suis fermement convaincu que pour la plupart, la motivation est la peur de la capacité de BSV à absorber l'économie mondiale et tous les autres projets «crypto» qui vont avec. Pour les autres, ou ceux qui ne comprennent pas le pouvoir du Bitcoin, ils sont entraînés dans une guerre culturelle qu'ils ne comprennent pas. Il est essentiel de comprendre les pouvoirs en jeu et leurs implications pour Bitcoin et l'économie mondiale. Une histoire brève Bitcoin a été lancé avec un "livre blanc" sur la liste de diffusion de cryptographie en 2008. Le pseudonyme « Satoshi Nakamoto » a déclaré une solution au problème de la double dépense. Or le problème de la double dépense de tous les précédents systèmes de paiement électronique était le seul facteur limitant l'adoption d'une monnaie électronique fonctionnelle. Il était impossible de prouver exactement qui possédait quelles unités d'argent sur leurs registres distribués, de sorte que les systèmes ne pouvaient pas faire confiance, et ces projets mourraient assez vite. Bitcoin a résolu ce problème avec un concept appelé « preuve de travail». Il poste la question: qui a brûlé le plus de puissance de calcul pour résoudre des énigmes arbitraires afin de rendre compte de l'état du registre d'une manière qui coûte de l'argent, de sorte qu'il y ait une incitation économique à tenir un compte honnête des avoirs de chacun. Ce processus est souvent appelé « exploitation minière » car les nœuds honnêtes qui maintiennent l'état du registre sont récompensés pour leur travail avec des Bitcoins toutes les dix minutes - un peu à la même manière d'un mineur d'or qui est récompensé par de l'or en échange de son travail. Étant donné que Bitcoin n'avait aucune valeur lors de son lancement, il était extrêmement facile à miner et également gratuit d'envoyer des tonnes de transactions. En théorie, il s'agissait d'un vecteur d'attaque par déni de service (DoS). Une attaque DoS ou DDoS se produit lorsque les nœuds sont inondés de plus de données qu'ils ne peuvent en gérer et qu'ils plantent. Sur un jeune réseau Bitcoin, un crash comme celui-ci aurait été considéré comme un échec du réseau, donc un plafond de 1 Mo de données pour chaque dix minutes de temps de transaction a été codé en dur dans le logiciel - semant la première graine de la guerre civile Bitcoin . De 2009 à 2017, cette limite de 1 Mo sur le total des transactions était l'aspect technique le plus controversé du bitcoin. Pourquoi est-ce important? Une seule et simple transaction Bitcoin est relativement petite du point de vue des données, donc 1 Mo toutes les dix minutes donne environ trois à sept transactions par seconde avant que le réseau ne devienne trop encombré. Satoshi Nakamoto a plaidé pour un nombre de transactions au niveau de Visa, ainsi que son successeur direct en tant que développeur principal du projet, Gavin Andresen! Certains des premiers Bitcoiners influents comme Mike Hearn et Jeff Garzik ont également plaidé pour plus de données par bloc pour permettre à Bitcoin de se développer pour rester un simple système de paiement électronique. Ils étaient pour des «gros blocs» contrairement au camp des «petits blocs» qui préconisaient une permanence de la limitation de 1 Mo de Bitcoin. Le camp des "petits blocs" estiment que Bitcoin n'est pas un réseau de paiement, mais plutôt qu'il s'apparente davantage à une banque décentralisée conçue pour stocker des Bitcoins qui ne bougent jamais: une sorte de coffre-fort d'or numérique. Ils voulaient que la limite de taille des blocs de 1 Mo reste permanente sous les auspices de chaque personne exécutant un «nœud bitcoin complet» sans avoir à payer trop d'espace sur le disque dur. Cela signifierait qu'en période de congestion, les frais de transaction deviendraient absurdement élevés, mais cela n'aurait pas d'importance car le bitcoin ne devrait pas être négocié sauf en grosses quantitées de toute façon. L'autre problème est que s'il est bon marché de rejoindre la gouvernance de Bitcoin, alors le réseau est facile à attaquer par sybil, et je dirais que BTC est régi par des sybilles à ce jour. Le camp des "gros-blocs" estime que tout le monde sur terre devrait être en mesure d'échanger et de faire ses affaires sur Bitcoin. Les "petits-blocs" pensent que tout le monde devrait être en mesure de gérer soi-même le registre mondial chez soi, mais que seules certaines personnes très riches devraient pouvoir effectuer des transactions. Après des années de querelles, en 2017, Bitcoin s'est scindé en deux chaînes distinctes, et en 2018, il s'est à nouveau divisé. Alors quelle est la différence entre ces versions ? BTC est actuellement la version qui a le prix le plus élevé, avec la plus petite taille de bloc et la plus grande puissance de calcul. Malheureusement, il est régi par des développeurs de logiciels et des sybilles qui contrôlent le consensus grâce à une utilisation intelligente de logiciels malveillants appelés «soft-fork» qui leur permet de saper les règles du Bitcoin. Ils utilisent ce pouvoir pour changer les règles des transactions en mentant aux nœuds et en leur disant de les valider quand même. Toute la culture BTC consiste à acheter du BTC afin de le conserver jusqu'à un moment dans le futur où il sera vendu. Les paiements avec BTC ou les transactions de toute nature sont méprisés. BCH est un réseau basé sur Bitcoin qui pense que les blocs devraient être à peine légèrement plus grands, mais ils ont également des développeurs en charge des règles, tout comme BTC, et ils pensent que Bitcoin devrait être catégorisé pour être utilisé uniquement pour le commerce de détail, mais rien de plus. Le réseau change de règles tous les six mois. Les transactions non commerciales sont en général méprisées. BSV est la version restaurée du protocole Bitcoin original avec tous les paramètres ouverts afin que les nœuds honnêtes puissent s'engager dans un consensus conformément au livre blanc de Bitcoin - par preuve de travail ! Le protocole est gravé dans la pierre afin que les développeurs de logiciels ne puissent pas bricoler les règles. Cela permet aux entreprises de planifier des décennies d'utilisation du réseau et d'investir en toute confiance. En tant que seul réseau bitcoin totalement sans autorisation, le commerce de toute nature est encouragé sur BSV. Tout, allant des réseaux sociaux aux expériences de science des données météorologiques ou aux tests de disponibilité du réseau, est encouragé. Paiements de détail, tokenisation, ou tout autre type de contrat intelligent est simple à déployer sans limitations. Bitcoin SV n'a aucun limite sauf l'esprit humain et l'esprit d'entreprise. Et c'est la racine de la haine envers BSV. Les "petits-blocs" ont investi toute leur réputation et leurs moyens de subsistance sur la notion que le bitcoin est incapable de s'adapter. Pendant des années, des experts présumés ont convaincu de nombreuses personnes que les limites de taille de bloc de 2 Mo, 8 Mo ou 22 Mo casseraient littéralement Bitcoin. Ils ont furieusement mis en jeux leur réputation sur ces fausses notions. Et ensuite, BSV a eu de nombreux blocs de plus de 100 Mo. En fait, il y en a même eu quelques-uns de plus de 300 Mo! prouvant que les petits-blocs se trompent sur les limites du réseau. Mais cette prise de conscience est une menace pour l'hégémonie du récit de Bitcoin. Depuis 2015, lorsque le Dr Craig Wright est apparu sur les lieux pour expliquer que le bitcoin avait en réalité ZERO limitations, il a créé un tollé massif parmi l'intelligentsia des petits-blocs. Les leaders d'opinion de l'époque étaient payés pour prendre la parole lors de conférences où ils expliquaient à tort que Bitcoin n'était rien d'autre qu'une réserve de valeur rare sans autre utilité. Le Dr Wright parlait de l'échelle illimitée du réseau, de son exhaustivité de Turing et d'autres notions inconcevables (à l'époque) sur Bitcoin. Sa passion et ses connaissances se sont heurtées à des calomnies et des railleries. Ils se sont concentrés sur l'attaque de son personnage au lieu de discuter de Bitcoin! C'est devenu l'une des principales méthodes d'attaque des petits-blocs. Lorsque de gros-blocs parlent des capacités de Bitcoin, ils sont ridiculisés en tant qu'escrocs et le sujet est toujours dirigé très loin de la discussion technique, car les petits-blocs savent bien qu'ils sortiraient perdants. Ils fouillent les dossiers personnels et cherchent des moyens de faire taire les gens du camp des grands-blocs de Bitcoin de la même manière que les guerriers de la justice sociale s'engagent dans la culture d'annulation contre leurs ennemis politiques. Qui est le Dr Craig Wright et que fait-il? Si vous ne le savez pas, Craig Wright est le scientifique en chef d'une société de recherche sur Bitcoin au Royaume-Uni appelée nChain : une société de 150 à 200 informaticiens. Craig dirige l'équipe qui étudie les possibilités de Bitcoin et de ses applications dans le monde. Il est l'un des experts en criminalité numérique les plus reconnus au monde avec les certifications SANS et GIAC ainsi que les titres GSE CISSP, CISA, CISM, CCE, GCFA, GLEG, GREM et GSPA. En outre, il est un polymathe multidisciplinaire de troisième cycle: un doctorat en informatique, économie et théologie et titulaire d'une maîtrise en statistique et en droit commercial international. En 2015, il a également été exposé par une publication conjointe de WIRED et Gizmodo en tant que Satoshi Nakamoto, le créateur de Bitcoin. Quelques jours après cette révélation, les gens qui le soutenaient ont vu leurs clés d'accès au code révoquées, et de nombreux autres ont été instantanément bannis. Craig a été mis sous enquête par le bureau des impôts australien pour ce qu'il considérait être une erreur de comptabilisation probable de ses bitcoins. Les retombées ont été agressives et rapides, avec une gigantesque armée de petits-blocs, organisée sur Reddit et autres forums, et nouvellement financée par l'argent de la startup pro-petits-blocs appelée «Blockstream». Leur message était clair: Bitcoin doit garder de petits blocs. Le Bitcoin ne peut pas évoluer, et toute personne proche de Craig Wright sera harcelée pour se conformer à une armée de comptes Twitter anonymes et sans visage. Au cours des années suivantes, Ira Kleiman, frère du défunt Dave Kleiman, a poursuivi Craig Wright pour sa part du prétendu «Partenariat Satoshi Nakamoto», affirmant que Dave était plus impliqué qu'il ne l'était réellement, et l'affaire est en cours actuellement, jusqu'à courant 2021. Ira Kleiman pense que Craig est Satoshi et a investi une fortune incalculable et a obtenu l'argent d'investisseurs extérieurs pour poursuivre sa poursuite. Il est clair que les bailleurs de fonds d'Ira pensent que Craig est également Satoshi. Les critiques qualifient souvent la révélation publique et le procès public de Wright de ternir énormément sa réputation, mais il convient de noter que les deux sont arrivés à Wright et qu'il ne souhaitait clairement pas être pris dans l'une ou l'autre situation. Au lieu de cela, Craig est un défenseur passionné de la vision d'un Bitcoin avec de gros blocs, appelant à la professionnalisation, à la légalisation et à l'utilisation mondiales de Bitcoin pour une utilisation à tous les niveaux du commerce. La réponse à la passion de Craig et à ses affirmations a été d'attaquer sa réputation et d'endosser Internet avec le surnom de «Faketoshi». Lorsque de simples brimades ont échoué contre le Dr Wright, des attaques ont été intensifiées pour remettre en question ses divers diplômes, des pétitions aux universités pour enquêter sur lui pour plagiat dans divers travaux, y compris des thèses de doctorat, etc. Wright a même revendiqué des menaces contre la vie des membres de sa famille et il y a plus qu'une petite preuve que, selon Ian Grigg, une des légendes de la cryptographie: «des gens sont morts pour Bitcoin, vraiment, des gens sont morts». Les attaques en cours Cela ne peut être assez souligné: la communauté des petits-blocs est construite autour de tactiques d'ingénierie sociale professionnelle. Gregory Maxwell, co-fondateur de la société Blockstream, a été formé à la pratique de l'ingénierie sociale et l'a utilisé de manière si subversive comme un outil de propagande pendant son mandat en tant que modérateur rémunéré de Wikipedia, qu'il a finalement été démis de ses fonctions avec les journaux d'administration citant une litanie d'infractions, notamment: «Gmaxwell s'est engagé dans la création de faux comptes en masse…» - Alhutch 00:05, 23 janvier 2006 (UTC) «Menaces, insultes grossières, usurpations d'identité d'un administrateur», -Husnock 03:18, 25 janvier 2006 (UTC) «Son comportement est scandaleux. Franchement, il est hors de contrôle à ce stade. Son comportement d'intimidation doit cesser.» - FearÉIREANN 19:36, 22 janvier 2006 (UTC) «Sa liste de contributions est hors de propos. C'est du vandalisme. C'est un comportement auquel je m'attendrais d'un éditeur en furie, ce que, franchement, Gmaxwell est.» - Splashtalk 20h00, 22 janvier 2006 (UTC) «Prétend être un administrateur, menaçant de bloquer les personnes qui ne sont pas d'accord avec lui, fait régulièrement des attaques personnelles» - SlimVirgin (talk) 12h22, 22 janvier 2006 (UTC) Il passe beaucoup de temps sur Reddit et d'autres forums à semer la peur sur les dangers des gros blocs, et il a été surpris en train de faire semblant d'être plusieurs comptes à la fois en train d'avoir de très longues discussions techniques sur Reddit destinées à submerger les nouveaux arrivants avec ce qui ressemble à un débat intellectuel. Qui d'autre est attaqué? L'autre cible commune de la machine de guerre anti-BSV est Calvin Ayre: le milliardaire à la tête de l'empire du groupe Ayre. Calvin est un entrepreneur canadien et antiguais qui a lancé un incubateur Internet à Vancouver au tout début du boom Internet. Fils d'un éleveur de porcs, Ayre est surtout connu en dehors de l'économie Bitcoin pour la création et la professionnalisation de l'industrie du jeu d'argent sur Internet. Plus particulièrement, sous la marque Bodog, Ayre a aidé à moderniser les lois financières américaines compliquées et obsolètes en poussant les limites dans les marchés gris qui existent où les dollars américains sont utilisés à travers les frontières pour s'engager dans un commerce juridiquement compliqué comme le jeu d'argent. Son travail dans ce domaine lui a valu une petite fortune et un passage sur une liste des «plus recherchés» pour blanchiment d'argent. C'est un point sur lequel les petits-blocs aiment se concentrer, mais ils le sortent complètement de son contexte. Calvin a finalement plaidé coupable à une accusation de délit, mais a été le fer de lance de la modernisation des lois et règlements américains qui existent aujourd'hui sur les marchés complètement ouverts et fonctionnels. Il est respecté pour son travail dans l'industrie du jeu, les médias et la philanthropie. Calvin est certainement le bienvenu aux États-Unis malgré la critique souvent citée et dépassée selon laquelle il est une sorte de hors-la-loi. Calvin Ayre Dans l'économie Bitcoin, Ayre est une figure de proue dans la gestion de nœuds Bitcoin honnêtes pendant plusieurs années sous les marques CoinGeek et TAAL, et il est un investisseur dans nChain ainsi que plusieurs startups dans l'espace BSV. Bien qu'il soit probablement le plus gros investisseur, il n'est pas le monolithe que les petits-blocs laisseraient croire aux critiques. Il est important de comprendre que des segments entiers de l'écosystème BSV existent complètement en dehors de son influence. Twetch, par exemple, est une entreprise indépendante appartenant à l'écosystème BSV, célèbre pour ses attaques contre les médias sociaux centralisés. Ils sont même connus pour se moquer des entreprises qui acceptent l'argent d'Ayre, en plaisantant que Calvin possède tout sauf Twetch. Bien sûr, ce n'est pas vrai. Un autre excellent exemple est l'investisseur / entrepreneur indépendant Jack Liu : ancien dirigeant de Circle et OKEX. Liu possède la marque de hackathons CambrianSV ainsi que des propriétés précieuses dans l'espace BSV telles que RelayX, Streamanity, Output Capital, FloatSV et Dimely. Les autres acteurs clés sont MatterPool Mining et leur écosystème Mattercloud: une joint-venture entre des acteurs indépendants de l'écosystème BSV, avec des connexions directes aux protocoles BoostPOW et 21e8 et des relations avec des développeurs BSV indépendants. Bien sûr, il existe également des marques précieuses financées par Ayre. Il s'agit notamment de la propriété partielle via l'investissement dans HandCash, Centi, TonicPow et Unwriter's Planaria Corp. Une autre mesure importante à prendre en compte est la distribution de la puissance de hachage. Alors qu'à un moment de l'histoire, les entreprises appartenant à Ayre représentent une quantité importante de hachage sur bitcoin, BSV est aujourd'hui en grande partie exploité par des mineurs concurrents de Binance, F2Pool, OKEX et ViaBTC - dont aucun n'est «ami» de BSV ou d'Ayre, mais beaucoup sont ennemis. Ces mineurs soulignent cependant la nature ouverte et sans permission de BSV pour permettre à quiconque de participer. Ayre est un acteur important, mais en aucun cas un contrôleur de la direction de la blockchain ou des entreprises indépendantes dans l'économie BSV. Mais pourquoi Craig poursuit-il tout le monde en justice ? Tout d'abord, et c'est crucial, le procès le plus important de Craig est l'affaire Kleiman. Les autres cas existent uniquement à cause de la diffamation publique du Dr Wright. Le hashtag #CraigWrightIsAFraud circule largement, poussé en grande partie par un mélange de personnages anonymes sur Twitter. Plus particulièrement Magnus Granath AKA «Hodlonaut» a été averti qu'une accusation publique de fraude courait à son encontre. La carrière du Dr Wright est en informatique et en criminalistique numérique, donc le déclarer publiquement une fraude cause un préjudice financier au Dr Wright dans son domaine d'expertise commerciale. Puisque «Hodlnaut» a refusé de cesser, on lui a envoyer une requête pour être vu au tribunal. Cela a causé le célèbre podcasteur de petits-blocs Peter McCormack à mendier d'être poursuivi aussi - en augmentant la rhétorique diffamatoire contre le Dr Wright. À la demande de McCormack, il a lui aussi été attaqué en justice pour être vu au tribunal. Cette ère de service a engendré la campagne #DelistBSV menée en grande partie par «CZ», le PDG charismatique de Binance Exchange. Divers autres échanges comme Shapeshift et Kraken ont publié des sondages publics demandant s'ils devaient emboîter le pas, et des petits-blocs bien organisés ont voté en masse pour retirer BSV de leurs échanges - citant la toxicité du Dr Wright pour avoir intenté des poursuites en diffamation contre Hodlonaut et McCormack. Finalement, BSV a été retiré de Binance, ShapeShift et Kraken. Il a également été noté publiquement par Coinbase et Gemini qu'ils ne soutiendraient pas du tout cette version de bitcoin à la suite du drame public. Au fur et à mesure que les choses progressaient, le fondateur de Bitcoin.com, Roger Ver, a également réalisé une vidéo publique déclarant Wright comme arnaqueur. C'était après avoir travaillé sournoisement avec les développeurs Bitcoin ABC pour coder des points de contrôle dans le logiciel ABC de Bitcoin Cash, divisant de manière permanente le réseau Bitcoin pour la deuxième et dernière fois - un acte pour lequel Roger est également poursuivi par d'autres parties privées en Floride. Roger Ver a été averti que des problèmes juridiques similaires se présenteraient à sa porte pour avoir diffamé le Dr Wright, mais les critiques publiques ont persisté jusqu'à ce que Roger soit également entendu devant le tribunal et fournisse la preuve de la fraude de Wright, sous peine de sanctions pour diffamation publique. Son cas est en instance à Antigua-et-Barbuda, où il est récemment devenu citoyen. Et ensuite il se passe quoi ? Nous avons établi l'histoire du Bitcoin, de la guerre civile, des attaques publiques contre Wright, Ayre et BSV. Au moment d'écrire ces lignes, nous pouvons revenir sur les attaques contre Thomas Lee, Tim Draper et Jimmy Wales pour avoir eu une proximité avec BSV. Malgré la pression sociale, le rapport Fundstrat de Lee a rendu un examen élogieux du protocole fixe et de l'évolutivité infinie de BSV. Lee et son équipe étaient heureux de prendre la parole lors des événements précédents de CoinGeek, même après le tollé public. Pour la conférence CoinGeek 2020 à New York, McCormack, Hodlonaut, « Arthur Van Pelt » et d'autres acteurs tels que le Dan Held de Kraken et une cacophonie de trolls anonymes sur Twitter ont mis à profit leur expérience de la culture d'annulation à la bolchevique pour faire pression sur les orateurs Gary Vaynerchuk , et d'autres orateurs prévus afin de les forcer à annuler leur participation à la conférence. Cette attaque sociale contre BSV, Dr. Wright, Ayre et les autres entreprises qui utilisent le réseau BSV pourrait être un cas gigantesque de fraude à la consommation. Ils trompent activement les gens en leur faisant croire que le protocole fixe et l'évolutivité infinie de Bitcoin SV sont en quelque sorte dangereux, alors qu'en fait, le protocole et le réseau sont imperméables à toutes les attaques, à l'exception de leur ingénierie sociale. Bitcoin SV s'est développé professionnellement avec un portefeuille de brevets de classe mondiale. Il est utilisé par des entreprises indépendantes pour réaliser des profits et il est exploité sur le marché libre par un groupe décentralisé de nœuds honnêtes qui se font concurrence. Le réseau est fixe, sécurisé et en croissance grâce aux investissements de petites entreprises et de gestionnaires de capitaux mondiaux. Les mensonges au contraire sont basés sur une campagne massive de dénigrement perpétrée par les communautés d'autres cryptomonnaie qui craignent l'adoption mondiale de BSV comme outil de commerce et ce que cela signifiera pour eux. L'histoire ne sera pas gentille avec ces manipulateurs et leurs réseaux qui sont financés par les fraudes probables des échanges de crypto-monnaies off-shore, le (très probablement) frauduleux Tether Stablecoin, et l'économie de "pump-and-dump" qui sous-tend 95% du volume de négociation de l'ensemble de l'économie cryptomonnaie actuelle. C'est une guerre civile. Il y aura toujours des victimes, mais alors que BTC et BCH se concentrent sur les ragots et les affaires illicites, BSV veut que le monde entier soit plus libre, plus souverain et plus capable de coopérer sur le registre mondial de la vérité afin que les entrepreneurs du monde puissent s'engager dans les grandes entreprises ou de simples nano-services sont rendus possibles uniquement par Bitcoin. Bitcoin est un test d'intelligence. Au fil du temps, les personnes intelligentes pourront voir à travers le brouillard de distorsion de la réalité créé pour confondre les innocents et reconnaître cela pour ce que c'est, une attaque coordonnée pour tenter de supprimer une technologie supérieure qui les rendrait obsolètes.

ASIC vs CPU mining . An ASIC Bitcoin miner is designed exclusively for the purpose of mining bitcoin. Though significantly more expensive to purchase, they are far more powerful (higher hash rate) and electricity-efficient than CPUs and GPUs (graphics cards) – used for mining in the early days of bitcoin – and even FPGAs (field programmable gate arrays), which were, in 2011, the most ... The Bitcoin.com mining pool has the lowest share reject rate (0.15%) we've ever seen. Other pools have over 0.30% rejected shares. Furthermore, the Bitcoin.com pool has a super responsive and reliable support team. Pi is a new digital currency being developed by a group of Stanford PhDs. For a limited time, you can join the beta to earn Pi and help grow the network.
