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.
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:
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.

ABSTRACTThe effects of the web by a number of companies have seduced a large number of users as these companies keep their data to prevent them from searching for alternatives. Likewise, these huge platforms have attracted applications to build their highest ecosystems before either severing access or actively opposing their interests when the applications became so successful. As a result, these walled gardens have effectively hindered innovation and monopolized large sections of the web. After the emergence of blockchain technology and decentralized cryptocurrencies, the need for applications to support decentralization has emerged. Several blockchain-based companies, applications and platforms have appeared in decentralization. In this research report, we will explain the approach adopted by the NEAR decentralization platform in designing and implementing the basic technology for its system. Near is a basic platform for cloud computing and decentralized storage managed by the community, designed to enable the open web for the future. On this web, everything can be created from new currencies to new applications to new industries, opening the door to an entirely new future.
1. INTRODUCTIONThe richness of the web is increasing day by day with the combined efforts of millions of people who have benefited from “innovation without permission” as content and applications are created without asking anyone. this lack of freedom of data has led to an environment hostile to the interests of its participants. And as we explained in the summary previously, web hosting companies have hindered innovation and greatly monopolized the web.
In the future, we can fix this by using new technologies to re-enable the permissionless innovation of the past in a way, which creates a more open web where users are free and applications are supportive rather than adversarial to their interests.
Decentralization emerged after the global financial crisis in 2008, which created fundamental problems of confidence in the heavily indebted banking system. Then the decentralized financial sector based on Blockchain technology has emerged since 2009.
Decentralized Blockchain technology has made it easy for decentralized digital currencies like Bitcoin to exchange billions of dollars in peer-to-peer transfers for a fraction of the price of a traditional banking system. This technology allows participants in the over $ 50 billion virtual goods economy to track, own and trade in these commodities without permission. It allows real-world goods to cross into the digital domain, with verified ownership and tracking just like that of the digital.
By default, the Internet where freedom of data enables innovation will lead to the development of a new form of software development. On this web, developers can quickly create applications from open state components and boost their efforts by using new business models that are enabled from within the program itself rather than relying on parasitic relationships with their users. This not only accelerates the creation of applications that have a more honest and cooperative relationship with its users, but also allows the emergence of completely new business built on them.
To enable these new applications and the open web, it needs the appropriate infrastructure. The new web platform cannot be controlled by a single entity and its use is not limited due to insufficient scalability. It should be decentralized in design like the web itself and supported by a community of distributors widely so that the value they store cannot be monitored, modified or removed without permission from the users who store this value on their behalf.
A new decentralization technology (Blockchain), which has facilitated decentralized digital currencies like Bitcoin, has made billions of dollars in peer-to-peer transfers at a fraction of the price of the traditional banking system. This technology allows participants in the $ 50 billion + virtual goods economy to track, own and trade in these goods without permission. It allows real-world goods to cross into the digital domain, with verified ownership and tracking just like that of the digital.
Although the cost of storing data or performing a calculation on the Ethereum blockchain is thousands and millions of times higher than the cost of performing the same functionality on Amazon Web Services. A developer can always create a “central” app or even a central currency for a fraction of the cost of doing the same on a decentralized platform because a decentralized platform, by definition, will have many iterations in its operations and storage.
Bitcoin can be thought of as the first, very basic, version of this global community-run cloud, though it is primarily used only to store and move the Bitcoin digital currency.
Ethereum is the second and slightly more sophisticated version, which expanded the basic principles of Bitcoin to create a more general computing and storage platform, though it is a raw technology, which hasn’t achieved meaningful mainstream adoption.
1.1 WHY IS IT IMPORTANT TO PAY THE EXTRA COST TO SUPPORT DECENTRALIZATION?Because some elements of value, for example bits representing digital currency ownership, personal identity, or asset notes, are very sensitive. While in the central system, the following players can change the value of any credits they come into direct contact with:
A typical user will trust a typical centralized application, despite its potential vulnerabilities, with everyday data and computation. Typically, only banks and governments are trusted sufficiently to maintain custody of the most sensitive information — balances of wealth and identity. But these entities are also subject to the very human forces of hubris, corruption and theft.
Especially after the 2008 global financial crisis, which demonstrated the fundamental problems of confidence in a highly indebted banking system. And governments around the
world apply significant capital controls to citizens during times of crisis. After these examples, it has become a truism that hackers now own most or all of your sensitive data.
These decentralized applications operate on a more complex infrastructure than today’s web but they have access to an instantaneous and global pool of currency, value and information that today’s web, where data is stored in the silos of individual corporations, cannot provide.
1.2 THE CHALLENGES OF CREATING A DECENTRALIZED CLOUDA community-run system like this has very different challenges from centralized “cloud” infrastructure, which is running by a single entity or group of known entities. For example:
2. NEARNEAR is a global community-run computing and storage cloud which is organized to be permissionless and which is economically incentivized to create a strong and decentralized data layer for the new web.
Essentially, it is a platform for running applications which have access to a shared — and secure — pool of money, identity and data which is owned by their users. More technically, it combines the features of partition-resistant networking, serverless compute and distributed storage into a new kind of platform.
NEAR is a community-managed, decentralized cloud storage and computing platform, designed to enable the open web in the future. It uses the same core technology for Bitcoin and Blockchain. On this web, everything can be created from new currencies to new applications to new industries, opening the door to an entirely new future.
NEAR is a decentralized community-run cloud computing and storage platform, which is designed to enable the open web of the future. On this web, everything from new currencies to new applications to new industries can be created, opening the door to a brand new future.
NEAR is a scalable computing and storage platform with the potential to change how systems are designed, how applications are built and how the web itself works.
It is a complex technology allow developers and entrepreneurs to easily and sustainably build applications which reap the benefits of decentralization and participate in the Open Web while minimizing the associated costs for end users.
NEAR creates the only community-managed cloud that is strong enough to power the future of the open web, as NEAR is designed from the ground up to deliver intuitive experiences to
end users, expand capacity across millions of devices, and provide developers with new and sustainable business models for their applications.
The NEAR Platform uses a token — also called “NEAR”. This token allows the users of these cloud resources, regardless of where they are in the world, to fairly compensate the providers of the services and to ensure that these participants operate in good faith.
2.1 WHY NEAR?Through focus, we find that Platforms based on blockchain technologies like Bitcoin and Ethereum have made great progress and enriched the world with thousands of innovative applications spanning from games to decentralized financing.
However, these original networks and none of the networks that followed were not able to bridge the gap towards mainstream adoption of the applications created above them and do not provide this type of standard that fully supports the web.
This is a result of two key factors:
Fixing these problems requires substantial and complex changes to current protocol architectures, something which existing organizations haven’t proven capable of implementing. Instead, they create multi-year backlogs of specification design and implementation, which result in their technology falling further and further behind.
NEAR’s platform and organization are architected specifically to solve the above-mentioned problems. The technical design is fanatically focused on creating the world’s most usable and scalable decentralized platform so global-scale applications can achieve real adoption. The organization and governance structure are designed to rapidly ship and continuously evolve the protocol so it will never become obsolete.
2.1.1 Features, which address these problems:1. USABILITY FIRST
The most important problem that needs to be addressed is how to allow developers to create useful applications that users can use easily and that will capture the sustainable value of these developers.
2. End-User Usability
Developers will only build applications, which their end users can actually use. NEAR’s “progressive security” model allows developers to create experiences for their users which more closely resemble familiar web experiences by delaying onboarding, removing the need for user to learn “blockchain” concepts and limiting the number of permission-asking interactions the user must have to use the application.
1. Simple Onboarding: NEAR allows developers to take actions on behalf of their users, which allows them to onboard users without requiring these users to provide a wallet or interact with tokens immediately upon reaching an application. Because accounts keep track of application-specific keys, user accounts can also be used for the kind of “Single Sign On” (SSO) functionality that users are familiar with from the traditional web (eg “Login with Facebook/Google/Github/etc”).
2. Easy Subscriptions: Contract-based accounts allow for easy creation of subscriptions and custom permissioning for particular applications.
3. Familiar Usage Styles: The NEAR economic model allows developers to pay for usage on behalf of their users in order to hide the costs of infrastructure in a way that is in line with familiar web usage paradigms.
4. Predictable Pricing: NEAR prices transactions on the platform in simple terms, which allow end-users to experience predictable pricing and less cognitive load when using the platform.
2.1.2 Design principles and development NEAR’s platform1. Usability: Applications deployed to the platform should be seamless to use for end users and seamless to create for developers. Wherever possible, the underlying technology itself should fade to the background or be hidden completely from end users. Wherever possible, developers should use familiar languages and patterns during the development process. Basic applications should be intuitive and simple to create while applications that are more robust should still be secure.
2. Scalability: The platform should scale with no upper limit as long as there is economic justification for doing so in order to support enterprise-grade, globally used applications.
3. Sustainable Decentralization: The platform should encourage significant decentralization in both the short term and the long term in order to properly secure the value it hosts. The platform — and community — should be widely and permissionlessly inclusive and actively encourage decentralization and participation. To maintain sustainability, both technological and community governance mechanisms should allow for practical iteration while avoiding capture by any single parties in the end.
4. Simplicity: The design of each of the system’s components should be as simple as possible in order to achieve their primary purpose. Optimize for simplicity, pragmatism and ease of understanding above theoretical perfection.
2.2 HOW NEAR WORKS?NEAR’s platform provides a community-operated cloud infrastructure for deploying and running decentralized applications. It combines the features of a decentralized database with others of a serverless compute platform. The token, which allows this platform to run also, enables applications built on top of it to interact with each other in new ways. Together, these features allow developers to create censorship resistant back-ends for applications that deal with high stakes data like money, identity, assets, and open-state components, which interact seamlessly with each other. These application back-ends and components are called “smart contracts,” though we will often refer to these all as simply “applications” here.
The infrastructure, which makes up this cloud, is created from a potentially infinite number of “nodes” run by individuals around the world who offer portions of their CPU and hard drive space — whether on their laptops or more professionally deployed servers. Developers write smart contracts and deploy them to this cloud as if they were deploying to a single server, which is a process that feels very similar to how applications are deployed to existing centralized clouds.
Once the developer has deployed an application, called a “smart contract”, and marked it unchangeable (“immutable”), the application will now run for as long as at least a handful of members of the NEAR community continue to exist. When end users interact with that deployed application, they will generally do so through a familiar web or mobile interface just like any one of a million apps today.
In the central cloud hosted by some companies today like: Amazon or Google, developers pay for their apps every month based on the amount of usage needed, for example based on the number of requests created by users visiting their webpages. The NEAR platform similarly requires that either users or developers provide compensation for their usage to the community operators of this infrastructure. Like today’s cloud infrastructure, NEAR prices usage based on easy to understand metrics that aren’t heavily influenced by factors like system congestion. Such factors make it very complicated for developers on alternative blockchain-based systems today.
In the centralized cloud, the controlling corporation makes decisions unilaterally. NEAR community-run cloud is decentralized so updates must ultimately be accepted by a sufficient quorum of the network participants. Updates about its future are generated from the community and subject to an inclusive governance process, which balances efficiency and security.
In order to ensure that the operators of nodes — who are anonymous and potentially even malicious — run the code with good behavior, they participate in a staking process called “Proof of Stake”. In this process, they willingly put a portion of value at risk as a sort of deposit, which they will forfeit if it is proven that they have operated improperly.
2.2.1 Elements of the NEAR’s PlatformThe NEAR platform is made up of many separate elements. Some of these are native to the platform itself while others are used in conjunction with or on top of it.
1. THE NEAR TOKEN
NEAR token is the fundamental native asset of the NEAR ecosystem and its functionality is enabled for all accounts. Each token is a unique digital asset similar to Ether, which can be used to:
a) Pay the system for processing transactions and storing data.
b) Run a validating node as part of the network by participating in the staking process.
c) Help determine how network resources are allocated and where its future technical direction will go by participating in governance processes.
The NEAR token enables the economic coordination of all participants who operate the network plus it enables new behaviors among the applications which are built on top of that network.
2. OTHER DIGITAL ASSETS
The platform is designed to easily store unique digital assets, which may include, but aren’t limited to:
The core platform, which is made up of the cloud of community-operated nodes, is the most basic piece of infrastructure provided. Developers can permissionlessly deploy smart contracts to this cloud and users can permissionlessly use the applications they power. Applications, which could range from consumer-facing games to digital currencies, can store their state (data) securely on the platform. This is conceptually similar to the Ethereum platform.
Operations that require an account, network use, or storage at the top of the platform require payment to the platform in the form of transaction fees that the platform then distributes to its community from the authentication contract. These operations could include creating new accounts, publishing new contracts, implementing code by contract and storing or modifying data by contract.
As long as the rules of the protocol are followed, any independent developer can write software, which interfaces with it (for example, by submitting transactions, creating accounts or even running a new node client) without asking for anyone’s permission first.
4. THE NEAR DEVELOPMENT SUITE
Set of tools and reference implementations created to facilitate its use by those developers and end users who prefer them. These tools include:
3. ECONOMICPrimarily economic forces drive the ecosystem, which makes up the NEAR platform. This economy creates the incentives, which allow participants permissionlessly organize to drive the platform’s key functions while creating strong disincentives for undesirable, irresponsible or malicious behavior. In order for the platform to be effective, these incentives need to exist both in the short term and in the long term.
The NEAR platform is a market among participants interested in two aspects:
3.1 NEAR ECONOMY DESIGN PRINCIPLESNEAR’s overall system design principles are used to inform its economic design according to the following interpretations:
1. Usability: End users and developers should have predictable and consistent pricing for their usage of the network. Users should never lose data forever.
2. Scalability: The platform should scale at economically justified thresholds.
3. Simplicity: The design of each of the system’s components should be as simple as possible in order to achieve their primary purpose.
4. Sustainable Decentralization: The barrier for participation in the platform as a validating node should be set as low as possible in order to bring a wide range of participants. Over time, their participation should not drive wealth and control into the hands of a small number. Individual transactions made far in the future must be at least as secure as those made today in order to safeguard the value they modify.
3.2 ECONOMIC OVERVIEWThe NEAR economy is optimized to provide developers and end users with the easiest possible experience while still providing proper incentives for network security and ecosystem development.
Summary of the key ideas that drive the system:
Founded in 2014, after 6 years of R & D as well as its expansion, and after nearly a year of extensive testing and preparation, IPFS (Interplanetary File System) was officially launched on the afternoon of October 15, 2020, UTC time. 12 hours after the mainnet went online, Its token price fluctuated between 50~70 USD/FIL. However, panic and pessimism began to spread between the IPFS community and FIL token holders. Based on the total amount of FIL (2 billion) and the unit price of 50 US dollars estimation, its market value has exceeded 100 billion US dollars, second only to BTC. As such a mega valued IPFS/FIL went online, if there is no enough application to support, the selling pressure after the FIL is gradually unlocked will become huge. According to calculations, on the first day of the mainnet launch, there will be 239,000 FILs to be sold. Assuming that the unit price is 30 USD, the released circulation will be 8 million USD. Assuming the unit price remains unchanged, the market will usher in a similar value on the 10th day. With a release amount of 15 million USD, it is very likely that the corresponding token price can be supported.submitted by Hayley_HOP to u/Hayley_HOP [link] [comments]
IPFS is a network transmission protocol designed to create persistent and distributed storage and sharing of files. In terms of its current active projects and companies, IPFS has added more than 5 billion files, involving multiple industries, and there are also many blockchain companies using this technology. When the IPFS mainnet and its Filecoin goes online, the market value will be based on the applications brought by the IPFS network. After Bitcoin and Ethereum, Filecoin is an upstart in the blockchain industry with a revolutionary technological breakthrough. The market predicts that Filecoin’s market value will surpass Bitcoin. Now let us analyze this project together that was given high hopes:
IPFS major features and disadvantages
The basic application of IPFS, Filecoin’s financial attributes and its incentive mechanism make it a very exciting global collaborative open source project. On this basis, the data of all mankind is stored in the IPFS network, and no one can tamper with it.
This magnificent scene provides at least three values for us:
What is HOP
The HOP protocol provides a decentralized and completely anonymous traffic service for people all over the world based on block chain. HOP combines P2P network transmission and block chain technology to establish a block chain micro-payment protocol based on the block chain transmission encryption protocol between P2P network bandwidth contributors and bandwidth users, and merge it into traffic mining. In the mining pool side, the whole protocol is built on the main network, which has Micro Payment and mining functions. In addition, HOP also supports traffic mining of ERC20 in any currency. So far, HOP is the only protocol that combines the above functions and is officially available in commercial application. It can provide terminal nodes for secure access to decentralized networks.
HOP features and comparison with IPFS
HOP and IPFS have certain similarities. The following table is a comparison of the two projects in terms of technology and application characteristics:
Why HOP might be a phenomenal project in the future
Compared with the disadvantages of IPFS which are not supporting for hot data storage, low storage efficiency, low disaster tolerance and the high threshold of providing storage capacity, The advantages of HOP are summarized as follows:
At present, most of the participants of HOP are top tier tech specialists, famous investors and politicians with global vision. We believe that projects like HOP, due to the open source and far-sighted technical foundation, which can not only achieve internal self-consistent circulation, but also integrate well with external ecology. Just as water conservancy is invisible, HOP has unlimited inclusiveness and scalability, and has a strong platform-level vitality!
We are looking forward to the accumulation of HOP, bringing a revolution in technology and applications to the blockchain and the practical universe!
In year 2008, POW mining machine is revolutionizing the distribution system from traditional currency which was created at the time of BITCOIN creation. In POW mining, If the work capacity for mining labor is larger, the higher chance to unlock Blocks will get, which purpose is to produce Bitcoins. POW 's birth was starting the first decentralized encrypted currency, digital currency has started to cut a striking figure rise in the financial market. According to the progress and development of Blockchain techniques, more and more people are participating in Bitcoin's investment and usage. POW mechanism's disadvantages are starting to emerge.submitted by AITDBlockchai to u/AITDBlockchai [link] [comments]
First, POW consensus mechanism is requiring mining labor to continuously using mining machine to do computing during mining process, this process will consume large capacity of electricity and mining machine usage cost, which will cause resources waste. As we mentioned in the previous class, purchasing more lotteries will improve the possibility of winning a prize, but it will cost a lot of money; Second, POW consensus mechanism is requiring all nodes to record processes for every production, transaction, transfer process on chain, which is causing time confirmation process slow for on-chain transaction. According to these two disadvantages, industry starts to continuously update based on POW consensus mechanism.
The nearest consensus mechanism for POW is POS, which is called legal rights prove. Unlike work capacity prove, POS mechanism do not need users to process massive calculation to unlock Blocks, but it is distributing Blocks according " Coin existing time from its generation", which is also called "coin age”. So called "Coin Age "is actually means that the product (times function)of the amount of coin users hold and times. Users can start exploring new Blocks when they get certain amount of "Coin Age". The longer of user's "Coin Age", the higher chance to discover new Blocks will get.
POS consensus algorithm is following "holding coins will produce profits" principle，Although current funds setting possess different approaches but equally satisfactory results, this setting is avoiding the resources waste problem which is causing by mining labors' mining process. Allowing digital currency production procedure to be simper, but the disadvantages are still existing in POS,User who possess older "coin age" will have higher chance to unlock Blocks and get rewards , those users who do not have coins can hardly unlock the Blocks. In the long term, " Poor people will be poorer, rich people will be richer”, This phenomenon is totally against the decentralization concept in digital currency.
DPOS was created after POS, which is stock authorized prove mechanism. This mechanism is coming up with a new concept based on the previous two mechanisms, the witness. Witness is the result of votes from on chain nodes, the mission is generating new Blocks within requiring times and gaining certain benefits for the works we did, EOS is the typical project which is based on DPOS. This rule is kind of like US congress, everyone has the right to vote, members from congress will use the power as the placement of civilian.
The birth of DPOS is further improving on-chain transaction confirmation speed, resources consuming problems during Blocks generating processes are resolved. At the meantime, this mechanism is transferring the digital currency processes from decentralization to weak centralization and half centralization. Witness failed to fulfill his duty is seriously influencing the operation procedure for the system.
Except the 3 mechanisms above, there is a more convenient, energy reduced consensus mechanism. POC.POC is being called capacity prove, the essence of POC is considering as one of the "contribution force algorithm, it replaces mining machine algorithm in POW mechanism by disc capacity. In POC algorithm, the larger capacity of user's mining machine discs, the higher chance will get Block reward, at the same time, the capacity of these discs can be used twice. Comparing to the previous 3 mechanism, POC mechanism possesses low barrier, resources exploitable and also possesses distribution traits advantages.
The star project IPFS in Block chain industries is using POC mining mechanism, but it has not grounded until now. Although POC mechanism possesses multiple advantages, its popularity is not positive. On one hand, it is because Blockchain techniques are under developing phase, the difficulty to achieve this type of technique is high. On the other hand, the popularity of POC mining and Bitcoin mining will need massive mining labor participation in order to run the system safely, therefore it will need certain amount of user’s numbers accumulation.
Overall, consensus mechanism is transferring to more convenient, more energy efficient, multiple directions. From this year, Blockchain industry is becoming focus point for the society, due to multiple projects are starting at the same time phenomenon, there will be more new consensus emerging in the future.
