Dragonchain Public Proposal TL;DR:Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per 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 on YouTube.
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.
Executive summaryDragonchain 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 PoCIn 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 transactionsOn 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.

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:
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.
How it works & scales
Architectural ScalingDragonchain’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.
Economic ScalingAn 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.
Scaled DeploymentDragonchain 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 ScalingDragonchain’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.
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 itBuilding 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...
ArchitectureDragonchain 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.
APIs (on chain & off)
Known issues or tradeoffs
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.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 considerDragonchain’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.
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 transactionsDragonchain 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.
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.
Users should be able to view their balances & transactions via a blockchain explorer-style interfaceFrom 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 & simpleWithdrawing 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
Documentation should be clear and completeFor full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.
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!
TIMECommunity 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.
Dragon DenDragonchain 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 elseUsers 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 elseThrough 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 offlineIf 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 availableTo 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 pointsSee above
Compatibility with HSMs & hardware walletsFor 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 directlyThis 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 scalableThis is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferredDragonchain is fully open source (see section on Disney release after conclusion).
ConclusionWhether 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 SourceThe 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.
Open SourceIn 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:
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.
Original OSSRELASE-10 document

claimAll will not work for most users. When you get to the claim step, please use the following tutorial: https://steemit.com/eos/@koyn/minimizing-the-cost-of-gas-when-claiming-eos-using-myetherwallet
REMEMBER YOU ONLY NEED TO REGISTER YOUR TOKENS IF YOU BOUGHT THEM ON AN EXCHANGE. YOU DON'T NEED TO CLAIM THEM.
So PLEASE REGISTER your Ethereum address NOW, don't forget about it, or plan on doing it some time in the near future.
- Go to the EOS website https://eos.io
- Scroll down and select "GET EOS"
- Tick all the required boxes and click "Continue"
- Scroll down and click "Register"
- Select Metamask, MyEtherWallet, or Ethereum Wallet
- Follow the guide.
- Remember that the reason you need to register your Ethereum ERC-20 address is to include your EOS tokens in order for the balance of your EOS Tokens to be included in the Snapshot if a Snapshot is created, you must register your Ethereum address with an EOS public key. The EOS snapshot will take place prior to the 1 June 2018. After this point your ERC-20 EOS tokens will be frozen. And you will be issued EOS tokens on the EOS blockchain.
“EOS.IO software utilizes the only known decentralized consensus algorithm proven capable of meeting the performance requirements of applications on the blockchain, Delegated Proof of Stake (DPOS). Under this algorithm, those who hold tokens on a blockchain adopting the EOS.IO software may select block producers through a continuous approval voting system. Anyone may choose to participate in block production and will be given an opportunity to produce blocks, provided they can persuade token holders to vote for them.
The EOS.IO software enables blocks to be produced exactly every 0.5 second and exactly one producer is authorized to produce a block at any given point in time. If the block is not produced at the scheduled time, then the block for that time slot is skipped. When one or more blocks are skipped, there is a 0.5 or more second gap in the blockchain.
Using the EOS.IO software, blocks are produced in rounds of 126 (6 blocks each, times 21 producers). At the start of each round 21 unique block producers are chosen by preference of votes cast by token holders. The selected producers are scheduled in an order agreed upon by 15 or more producers.
Byzantine Fault Tolerance is added to traditional DPOS by allowing all producers to sign all blocks so long as no producer signs two blocks with the same timestamp or the same block height. Once 15 producers have signed a block the block is deemed irreversible. Any byzantine producer would have to generate cryptographic evidence of their treason by signing two blocks with the same timestamp or blockheight. Under this model a irreversible consensus should be reachable within 1 second."
"The EOS Tokens do not have any rights, uses, purpose, attributes, functionalities or features, express or implied, including, without limitation, any uses, purpose, attributes, functionalities or features on the EOS Platform."
"In sum, Defendants capitalized on the recent enthusiasm for blockchain technology and cryptocurrencies to raise funds through the ICO, illegally sold unqualified and unregistered securities, used a Swiss-based entity in an unsuccessful attempt to evade U.S. securities laws, and are now admittedly engaged in the conversion, selling, and possible dissipation of the proceeds that they collected from the Class through their unregistered offering."To ensure EOS tokens are not classed as a unregistered security block.one has made it clear that they are creating the EOS software only and won’t launching a public blockchain themselves. This task is left down to the community, or more precisely, the Block Producers (BPs). The following disclaimer is seen after posts from block.one:
"block.one is a software company and is producing the EOS.IO software as free, open source software. This software may enable those who deploy it to launch a blockchain or decentralized applications with the features described above. block.one will not be launching a public blockchain based on the EOS.IO software. It will be the sole responsibility of third parties and the community and those who wish to become block producers to implement the features and/or provide the services described above as they see fit. block.one does not guarantee that anyone will implement such features or provide such services or that the EOS.IO software will be adopted and deployed in any way.”It is expected that many blockchains using eos.io software will emerge. To ensure DAPPs are created on an ecosystem that aligns with the interests of block.one a $1bn fund will be has been created to incentivise projects to use this blockchain.
“A lot of token distributions only allow a small amount of people to participate. The EOS Token distribution structure was created to provide a sufficient period of time for people to participate if they so choose, as well as give people the opportunity to see the development of the EOS.IO Software prior to making a decision to purchase EOS Tokens.”
“block.one intends to engage an independent third party auditor who will release an independent audit report providing further assurances that block.one has not purchased EOS Tokens during the EOS Token distribution period or traded EOS Tokens (including using proceeds from the EOS Token distribution for these purposes). This report will be made available to the public on the eos.io website.”
"DDoS'ing a block producing is not as simple as knowing their IP address and hitting "go". We have distributed systems engineers in each of our candidate groups that have worked to defend DDoS systems in their careers. Infrastructure can be built in a way to minimize the exposure of the Block Producing node itself and to prevent a DDoS attack. We haven't published our full architecture yet but let's take a look at fellow candidate EOSphere to see what we mean. As for the launch of the network, we are assuming there will be attacks on the network as we launch. It is being built into the network launch plans. I will reach out to our engineers to get a more detailed answer for you. What also must be considered is that there will be 121 total producing and non-producing nodes on the network. To DDoS all 121 which are located all around the world with different security configurations at the exact same time would be a monumental achievement."
"The only way to maintain the integrity of a community is for the community to have control over its own composition. This means that open-entry systems built around anonymous participation will have no means expelling bad actors and will eventually succumb to profit-driven corruption. You cannot use stake as a proxy for goodness whether that stake is held in a bond or a shareholder’s vote. Goodness is subjective and it is up to each community to define what values they hold as good and to actively expel people they hold has bad.
The community I want to participate in will expel the rent-seeking vote-buyers and reward those who use their elected broadcasting power for the benefit of all community members rather than special interest groups (such as vote-buyers). I have faith that such a community will be far more competitive in a market competition for mindshare than one that elects vote buyers."

Cardano is a cryptocurrency running on a decentralized blockchain platform that is under development. The project team strives to gain the trust of users by ensuring transparency of everything that happens in the system.
THE HISTORY OF THE EMERGENCECardano (ADA) was created by a team led by Charles Haskinson, who previously worked on Ethereum, but left the number of cryptocurrency developers before the ICO. In 2014, he and Jeremy wood formed IOHK. In the same year, a group of Japanese investors signed a 6-year contract with this firm to create a blockchain project based on the use of algorithms for independent execution of exchange operations with different types of assets.
The platform was named after Gerolamo Cardano, an Italian mathematician, engineer, philosopher and astrologer. The Ada token was composed of 3 letters of the scientist's surname so that the name of the world's first female programmer-Ada Lovelace - turned out.
The currency ICO was held in several stages in 2015-2017. as a result, $62 million was collected during operations only within the ADA Coin system. Until 2019, the developers plan to launch a number of decentralized applications and services for the implementation of smart contracts.
In the beginning, the team warned that the low speed of operations (only 5-10 transactions per second) can affect the rate of cryptocurrency. Experts plan to increase the speed of transactions by introducing the system of bandwidth nodes, the Protocol of which will be written in the programming language Haskell. Also prevent the success of the project could reputation of the author of the idea of Charles Hoskinson, who left his previous job without explanation. But the cost of the coin was not affected by these factors, the prospects for the project are good.
The success of the project is also facilitated by the fact that it is engaged in 3 institutions performing different functions:
MAIN FEATURES OF CARDANO COINCardano (ADA) is a cryptocurrency whose task is to secure smart contracts between users on terms beneficial to both parties. Such principles of asset exchange will be the basis for further development of digital currencies. The Ada token has many pluses, but there are also minuses.
HOW TO MINE CARDANOThe Cardano platform is based on the Proof of Stake algorithm. This means that the chances of a miner to create a block are directly proportional to the assets available to him, the results of work on solving a mathematical problem do not matter.
Advantages of Cardano mining:
WHERE AND HOW TO BUY CARDANO ADA CRYPTOCURRENCYCardano coins are traded in pairs with other cryptocurrencies on most exchanges (Finance, Bitrix, Http, Upbit, Bithumb, Cryptopia, etc.). There are exchangers (Prostocash, Xchange, 60 cek) and Exmo exchange, where you can buy Cardano cryptocurrency for rubles and other Fiat currency, after exchanging it for bitcoins or ethers. You can pay in exchangers via PayPal or Bank card.
Purchase instructions ADA:
Purchase on Binance
Crypto exchanges provide the ability to store funds, but it is better to withdraw tokens to the wallet immediately after purchase. If this is not possible, you should take care of the security of your account. Asset storage is better not to trust little-known exchanges.
CARDANO WALLETUntil March 2018, the only e-wallet in which ADA could be stored was Daedalus. There are versions for Windows, Mac and Linux. The wallet is suitable for anonymous transactions. The Cardano team plans to issue a debit card that can be replenished through this e-wallet.
Daedalus installation instructions:
In March, it became possible to store ADA tokens in the Centra wallet. This means that the currency can be withdrawn using the Centra card in 36 million terminals around the world.
Web wallets are popular because of convenience. Many sites offer to download them to store ADA, but this should not be done, so as not to fall for the tricks of scammers. On the official website of the company there is no data on cooperation with owners of online wallets.
WHAT ARE THE PROSPECTS FOR THE ADA CRYPTOCURRENCYGiven the big plans of Cardano developers, the forecast for 2020 regarding this cryptocurrency is good. If the team implements its ideas to expand the use of coins, ADA may become popular in the market after a while, despite the fall in user confidence in cryptocurrencies.
Road map of Cardano
The author of the platform Hoskinson said that the work on scaling the data will not yield results until 2019. Developers want to introduce innovative technologies into their project, their creation and research takes a lot of time. By the end of the year, it is planned to standardize the protocols and improve the reliability of the system, but the achievement of these goals may be delayed due to the complexity of the ideas. At this stage of operation of the platform, information about the use of high technologies in support of Cardano's work is not proven.
Cryptocurrency faces competition among firms providing such services. It interferes with its development. Specialists working on improving Litecoin and Dash use similar principles when conducting transactions. Ripple plans to become an element combining currencies recognized as official and digital assets, making it more attractive to investors.
The exclusivity of the project is that its development is scientifically justified. But this is not a significant advantage, as most traders do not want to spend time figuring out the details of the technical side of the project, and are interested in its functionality.
If the Cardano project team fulfills its plans by the end of the year, the prospect of this currency is quite good. The success of ADA depends on how convenient the token will be to use.

Earlier on, when Bitcoin (BTC) arrived on the scene, most cryptocurrency enthusiasts held on to their coins, as there were only so many places they could be spent. Nowadays, the list of marketplaces and retailers accepting Bitcoin and other cryptocurrencies is significantly larger, providing crypto enthusiasts with more options for making real-world purchases.
After all, with recognizable organizations like Microsoft and Wikipedia now accepting Bitcoin as payment, conversations about Bitcoin and the power of cryptocurrencies are becoming more prominent.
Currently, several fast-food restaurants and coffee shops have started accepting Bitcoin as payment. This will likely provide traction for mass adoption as cryptocurrency payments become increasingly commonplace in day-to-day purchases.
Granted, there are some jurisdictions that do not consider Bitcoin or any other cryptocurrency as legal tender. Despite this set back, even big tech companies like Facebook are coming up with payment systems that mimic cryptocurrencies.
Here are some of the leading retailers, merchants and companies that will let you book flights and hotels, buy coffee or pizza, or even go to space with crypto.
Pay for a burger in Germany with cryptoThe German branch of fast-food restaurant chain Burger King now claims to accept Bitcoin as payment for its online orders and deliveries, but this is not the first time Burger King has warmed up to Bitcoin as a form of payment.
The company, headquartered in Florida in the United States, had its Russian branch announce in 2017 that it would start accepting Bitcoin payments, but it ultimately did not take off. The global fast-food retailer reports an annual revenue of about $20 billion and serves about 11 million customers around the world. If all its outlets move to accept Bitcoin as payment, cryptocurrency adoption would inevitably spread.
Spend crypto at Starbucks and other placesFor crypto payments to gain traction, merchants need to implement systems that enable swift and easy cryptocurrency spending. Starbucks is one of the companies taking advantage of this concept through Flexa, a U.S.-based payment startup that is helping the cafe giant, as well as dozens of other companies, accept cryptocurrency payments.
The company developed an app called Spedn that enables crypto holders to make purchases with merchants like Starbucks. The company’s CEO believes that by making cryptocurrencies spendable in the mainstream, commerce will realize the full benefit of blockchain technology all over the world.
Crypto enthusiasts in Silicon Valley’s Palo Alto might already be familiar with Coupa Cafe for other reasons apart from its coffee and food. Through its partnership with a Facebook software developer, Coupa Cafe has been accepting Bitcoin as payment since 2013.
Reports show that the cafe received a steady stream of Bitcoin revenue as soon as they started implementing crypto payments — a clear sign of how eager its customers were to pay in Bitcoin. Coupa Cafe is among the few physical businesses in Palo Alto that accept Bitcoin at the moment. The cafe owners believe that their collaboration with the Facebook software engineer will create more traction in terms of Bitcoin adoption.
Buy food with cryptoWith over 50,000 takeaway restaurants listed on its United Kingdom-based site, OrderTakeaways is one of the surest ways to get a pizza paid for with crypto delivered to your doorstep. The company has been accepting Bitcoin payments for online takeout orders since 2018. And other similar services include the Korean platform Shuttledelivery as well as German-based service Lieferando and its subsidiaries in several other countries.
Apart from online orders, crypto can also be spent at a regular Subway restaurants. As early as 2013, several Subway branches started accepting Bitcoin as payment. Now, for a fraction of a Bitcoin, a Subway sandwich can be purchased at select restaurants.
Pay with Bitcoin to tour spaceBesides buying food and inexpensive, day-to-day items with crypto, a trip to space can now be bought with Bitcoin. That’s right. Richard Branson’s space tourism company, Virgin Galactic, started accepting Bitcoin as payment as far back as 2013. Although Branson’s predicted date for the first commercial flight has been pushed back several times, the company achieved its first suborbital space flight last year. Perhaps soon, people will be able to tour the moon on crypto’s dime.
Buy jewelry with BitcoinA brick-and-mortar American jewelry company called Reeds Jewelers accepts Bitcoin for both its physical and online stores. What’s more, if a purchase is worth more than $25,000, the company provides free armored delivery for safety. Other jewelry companies accepting Bitcoin include Blue Nile Jewelry, Stephen Silver Fine Jewelry and Coaex Jewelry, to name a few.
A big advantage of purchasing large ticket items — like a diamond — with crypto is that it makes moving around large amounts of money cheap and effortless. Reports show that more Silicon Valley investors are buying jewelry with Bitcoin. Last year, Stephen Silver Fine Jewelry reported a 20% growth in crypto transactions, leading to a boost in the company’s sales. The company has been accepting Bitcoin since 2014.
Send and redeem gift cards with BitcoinGyft, a digital platform that allows users to buy, send and redeem gift cards, was one of the first merchants enabling cryptocurrency adoption to gain traction in the real world. The mobile gift card app allows Bitcoin to be used to purchase gift cards from several retailers, some of which include Burger King, Subway, Amazon and Starbucks. The company has also partnered with popular crypto exchange Coinbase to enable users to buy gift cards from their Coinbase wallets.
Travel and pay in BitcoinIf a traveler only has Bitcoin at their disposal, the following merchants will gladly offer services in exchange for it. TravelbyBit, a flight and hotel booking service, accepts cryptocurrencies like Bitcoin, Binance Coin and Litecoin (LTC) as payment.
With a network of over 300 crypto-friendly merchants, the platform is one of the biggest supporters of crypto adoption. TravelbyBit can also alert you to upcoming blockchain events in order to interact with other crypto enthusiasts from around the globe. Other platforms to book flights with crypto include Destinia, CheapBizClass, CheapAir, AirBaltic, Bitcoin.Travel and ABitSky, among others.
Use crypto to book a five-star hotel in ZurichIf ever one finds themselves traveling to Zurich Switzerland, either BTC or Ether (ETH) can be used to pay for a stay in a five-star hotel in Zurich. In May 2019, five-star hotel and spa Dodler Grand announced that it will start accepting Bitcoin and Ether as payment.
The hotel has partnered with a fintech firm Inacta as well as Bity (a Swiss-based crypto exchange) to facilitate the payment and conversion of crypto to fiat money. The hotel boasts an amazing view of the Swiss landscape among other enticing amenities that come with a five-star hotel.
Pay for electronics and more with cryptoFor all the gadget lovers, there are a bunch of platforms that allow electronic purchases with cryptocurrency. Newegg, for instance, is an electronic retail giant that uses BitPay to process payments made with digital currencies. Even though one cannot get refunds for Bitcoin purchases, Newegg has a good reputation for quality items.
Plus, the company boasts its being among the first merchants to support cryptocurrency adoption. Other platforms for gadget junkies include Eyeboot (a platform that sells crypto mining rigs in exchange for crypto), Microsoft, FastTech and Alza (a U.K.-based online store that sells phones and beauty products).
An ever-expanding listIt seems clear that more retailers are warming up to the idea of accepting cryptocurrencies. There is still a long way to go before full adoption can be achieved, but many companies have nevertheless benefited from being early adopters. Despite the volatile price movements of cryptocurrencies, all evidence points to a future cashless society that uses digital currencies, and crypto is leading the way.
