QuarkChain aims to obtain an extremely high TPS while maintaining the network’s decentralization and security.  This makes Quarkchain unique from other blockchain networks.\n\n>What is QuarkChain’s Vision?\n\n1. Introducing a novel sharding-based blockchain architecture that aims to meet the global commercial standard.\n2. Greatly expanding the usability of blockchain technology without sacrificing its core features of security and decentralization.\n3. Helping move blockchain into the next generation by increasing the current TPS capacity several-thousand fold of what it is now, to a projected about 100,000 TPS.\n4. Building a project that is free of congestion and affordable for all usage scenarios that demand speed and volume.\n5. Building a high-throughput network to support applications such as distributed social media, high frequency trading, Internet of Things (loT), gaming and payment.\n\nIt’s worth noting that the ultimate goal of any blockchain is to extend the scalability as high as possible while keeping security and decentralization in an appropriate level, but a simple pursuit of scalability usually sacrifices decentralization and security.\nTherefore, the QuarkChain Network aims to solve scalability problem of the current blockchain based systems.\n\n>How can QuarkChain achieve better scalability?\n\nThe QuarkChain Network adopts the divide-and-conquer idea to separate the two main functions in two layers and thus enhance the scalability while guaranteeing the security.\n\nThe first layer is an elastic sharding blockchain layer, which contains a list of minor blockchains (shards).\nEach shard processes a sub-set of all transactions independently.As the number of shards increases, shards can process more transactions concurrently.\n\nQuarkChain Network fully supports cross-shard transactions.Cross-shard transactions in QuarkChain can be issued at any time, and confirmed in minutes.  \n\nThe speed of cross-shard transactions increases linearly as the number of shards increases. As a result, the system capacity increases.\nThe second layer is a root blockchain (rootchain) that confirms all blocks from sharded blockchains. Specifically to prevent double spending attacks, half of the networks hash power (50%) is devoted to the root blockchain.\n\nThe first layer is flexible to be resharded as needed without changing root layer.Having two-layered structure, Quarkchain encourages weak miners to mine directly without joining mining pools.\n\n>QuarkChain addresses the three main challenges of a blockchain — security, decentralization and scalability:\n\nQuarkChain has the ability to offer guaranteed security through market-driven collaborative mining.\n\nQuarkChain encourages decentralization by allowing multiple cheap nodes to form a cluster running as a super-full node.\n\nQuarkChain achieves scalability by increasing the number of shards.\n\n\n>System Operational Aspects of the QuarkChain Network:\n\nOn-Chain and Off-Chain Transactions: Some applications need both on-chain and off-chain handling.The two-layer sharding structure of the QuarkChain Network makes this on-chain and off-chain handling very flexible. This opens more opportunities and applications.\n\nSmart Contract: EVM(Ethereum virtual machine) is the most widely used execution engine for smart contracts.The QuarkChain Network will support smart contracts via EVM. Most of the existing dApps built on top of EVM can be directly deployed on the platform of the QuarkChain Network.\n\nAccount Management: There is only one account needed for the entire blockchain (shards) in QuarkChain. All cryptocurrencies from different shards are stored in one smart wallet.\n\nSmart Wallet: Smart wallet will simplify account management during transactions so that a user does not need to be aware of the underlying detailed in-shard/cross-shard operations.\n\n>Role of Quarkchain Token:\n\nQuarkChain tokens (QKC) are ERC-20 compatible tokens distributed on the Ethereum blockchain. After the QuarkChain mainnet is launched, these ERC-20 tokens will be converted to mainnet’s token by premining. Future QKCs will be produced by miners. Total supply is 10 billion QKC. Token sale 20%, Team 15%, Advisors 5%, Foundation 15%, Mining, community and marketing 45%.\n\nThe goal of introducing QKC is to provide a convenient and secure mode of payment and settlement between participants who interact within the ecosystem on the QuarkChain Network.\nQKC token will be used as Value carrier, Transaction currency and Contribution incentive.\n\n>Business development:\n\nMobile Decentralized Applications: The QuarkChain Network has robust infrastructure with mobile-oriented design that can fully support mobile DApps (Dapps2go).Furthermore, on-chain developer tools will be provided to create an Android-friendly environment, making DApps2go development as simple as possible.\n\nMinimum Viable Products with On-chain Fast Evolution: The QuarkChain Network aims to shorten product development cycles by adopting build-measure-learn feedback loop from the lean startup methodology.Thus, developers have been allowed to run minimal viable products on-chain.\n\nDemand Oriented Business Scenario: With the help of the decentralized ledger and advanced cryptographic protected private key of the QuarkChain Network it is believed that there can be DApps to support small business owners by providing an affordable and easy handling anti-counterfeit solution. This solution can also be used for education systems for validating diplomas and laboratory raw data.\n\nThe QuarkChain Network for Internet of Things: The QuarkChain Network will play an important role as a platform to support IoT applications with a large number of low-cost devices and speedy transactions.\n\nThe QuarkChain Network for AI and Big Data: Blockchain provides a digital platform for economic transactions and thus it is highly related to artificial intelligence (Al). Besides, QuarkChain Network offers reshardable functionality to reduce the transaction cost.\n\nAs blockchain grows, the amount of data increases fast .These data will generate great value for the company or the whole world’ s economy. The\nQuarkChain Network is open to collaborate with data analysts and economists to develop new economic models to further enhance the design of the QuarkChain Network with higher efficiency.\n\n>Main features of QuarkChain at a glance:\n\nReshardable two-layered blockchain: QuarkChain consists of two layers of blockchains. Elastic sharding blockchains (shards) are applied as the first layer, and a root blockchain as the second layer that confirms the blocks from the first layer.The first layer is flexible to be resharded as needed without changing the root layer.\n\nGuaranteed security by market-driven collaborative mining: To ensure the security of all transactions, a game-theoretic framework is designed for incentives, where at least 50% of overall hash powers are allocated to the root chain to prevent double spending attack on any transactions.\n\nAnti-centralized horizontal scalability: In any blockchain network with a high TPS, a super-full node can be extremely expensive, which encourages centralization. In contrast, QuarkChain allows multiple cheap nodes forming a cluster to replace a super-full node.\n\nEfficient cross-shard transactions: Cross-shard transactions in QuarkChain can be issued at any time, and confirmed in minutes. The speed of cross-shard transactions increases linearly as the number of shards increases.\n\nSimple account management: There is only one account needed for the entire blockchains (shards) in QuarkChain. All cryptocurrencies from different shards are stored in one smart wallet.\n\nTuring-complete smart contract platform: The QuarkChain network supports Turing-complete smart contracts and has adopted the Ethereum Virtual Machine (EVM) to allow for easy migration of existing EVM decentralized Apps onto the QuarkChain platform.\n\n\n>QuarkChain VS Zilliqa:\n\nQuarkChain and Zilliqa are the only projects with sharding on testnet implementation and here are the differences:\n1. Zilliqa does not support turing-complete smart contract, while QuarkChain supports turing-complete such as EVM.\n2. Zilliqa only supports network sharding, while QuarkChain supports network and state sharding.\n3. QuarkChain has scalable cross-shard transaction, while Zilliqa’s cross-shard transaction is pretty limited.\n\n>Conclusion: \n\nQuarkchain is backed by a strong and experienced team that has the ability to execute the project successfully. QuarkChain could be one of the most successful projects of 2018 and has the capability to play vital role in crpyto world in the years ahead.\n\n>For more information, you may visit the following links:\n\nWebsite: https://quarkchain.io/\n\nTelegram: https://t.me/quarkchainio\n\nMedium: https://medium.com/@quarkchainquark\n\nFacebook: https://www.facebook.com/quarkchain.io\n\nTwitter: https://twitter.com/Quark_Chain",

      "body": "What is QuarkChain?\n\nQuarkchain is a decentralized, secure and scalable permission-less blockchain architecture that aims to deliver 1,000,000+ on-chain TPS by applying sharding technology.(Sharding is a technique in which a large database is partitioned into smaller parts, so that the data can be processed in parallel).\n\nWhy QuarkChain?\n\nAs the global financial transaction volume in all electronic payments grows, the low capacity of the current blockchain-based networks cannot cope with the world’s commerce anytime.\nCurrently, major blockchains cannot even securely handle the volume of financial transactions that occur on centralized payment systems like Visa.\nBitcoin’s and Ethereums 10–20 TPS are many orders of magnitude away from this and even further from the TPS that loT micropayments would require.\nTo make the blockchain technology an incredible game changer in world’s commerce, a network that can handle a large volume of transactions without compromising on security and decentralization must be developed.\nAspiring for such an efficient blockchain architecture led to the evolution of Quarkchain.\n\nWhat makes Qurakchain so unique?\n\nEven though there are networks that achieved high TPS, (for example, Alipay touched 200+K TPS last year), it is challenging to achieve tradeoffs among scalability, decentralization, and security. QuarkChain aims to obtain an extremely high TPS while maintaining the network’s decentralization and security.  This makes Quarkchain unique from other blockchain networks.\n\nWhat is QuarkChain’s Vision?\n\n1. Introducing a novel sharding-based blockchain architecture that aims to meet the global commercial standard.\n2. Greatly expanding the usability of blockchain technology without sacrificing its core features of security and decentralization.\n3. Helping move blockchain into the next generation by increasing the current TPS capacity several-thousand fold of what it is now, to a projected about 100,000 TPS.\n4. Building a project that is free of congestion and affordable for all usage scenarios that demand speed and volume.\n5. Building a high-throughput network to support applications such as distributed social media, high frequency trading, Internet of Things (loT), gaming and payment.\nIt’s worth noting that the ultimate goal of any blockchain is to extend the scalability as high as possible while keeping security and decentralization in an appropriate level, but a simple pursuit of scalability usually sacrifices decentralization and security.\nTherefore, the QuarkChain Network aims to solve scalability problem of the current blockchain based systems.\n\nHow can QuarkChain achieve better scalability?\n\nThe QuarkChain Network adopts the divide-and-conquer idea to separate the two main functions in two layers and thus enhance the scalability while guaranteeing the security.\nThe first layer is an elastic sharding blockchain layer, which contains a list of minor blockchains (shards).\nEach shard processes a sub-set of all transactions independently.As the number of shards increases, shards can process more transactions concurrently.\nQuarkChain Network fully supports cross-shard transactions.Cross-shard transactions in QuarkChain can be issued at any time, and confirmed in minutes.  \nThe speed of cross-shard transactions increases linearly as the number of shards increases. As a result, the system capacity increases.\nThe second layer is a root blockchain (rootchain) that confirms all blocks from sharded blockchains. Specifically to prevent double spending attacks, half of the networks hash power (50%) is devoted to the root blockchain.\n\nThe first layer is flexible to be resharded as needed without changing root layer.Having two-layered structure, Quarkchain encourages weak miners to mine directly without joining mining pools.\n\nQuarkChain addresses the three main challenges of a blockchain — security, decentralization and scalability:\n\n> QuarkChain has the ability to offer guaranteed security through market-driven collaborative mining.\n> QuarkChain encourages decentralization by allowing multiple cheap nodes to form a cluster running as a super-full node.\n\n> QuarkChain achieves scalability by increasing the number of shards.\n\nSystem Operational Aspects of the QuarkChain Network:\n\n> On-Chain and Off-Chain Transactions: Some applications need both on-chain and off-chain handling.The two-layer sharding structure of the QuarkChain Network makes this on-chain and off-chain handling very flexible. This opens more opportunities and applications.\n> Smart Contract: EVM(Ethereum virtual machine) is the most widely used execution engine for smart contracts.The QuarkChain Network will support smart contracts via EVM. Most of the existing dApps built on top of EVM can be directly deployed on the platform of the QuarkChain Network.\n> Account Management: There is only one account needed for the entire blockchain (shards) in QuarkChain. All cryptocurrencies from different shards are stored in one smart wallet.\n> Smart Wallet: Smart wallet will simplify account management during transactions so that a user does not need to be aware of the underlying detailed in-shard/cross-shard operations.\n\nRole of Quarkchain Token:\n\nQuarkChain tokens (QKC) are ERC-20 compatible tokens distributed on the Ethereum blockchain. After the QuarkChain mainnet is launched, these ERC-20 tokens will be converted to mainnet’s token by premining. Future QKCs will be produced by miners. Total supply is 10 billion QKC. Token sale 20%, Team 15%, Advisors 5%, Foundation 15%, Mining, community and marketing 45%.\nThe goal of introducing QKC is to provide a convenient and secure mode of payment and settlement between participants who interact within the ecosystem on the QuarkChain Network.\nQKC token will be used as Value carrier, Transaction currency and Contribution incentive.\n\nBusiness development:\n\n> Mobile Decentralized Applications: The QuarkChain Network has robust infrastructure with mobile-oriented design that can fully support mobile DApps (Dapps2go).Furthermore, on-chain developer tools will be provided to create an Android-friendly environment, making DApps2go development as simple as possible.\n\n> Minimum Viable Products with On-chain Fast Evolution: The QuarkChain Network aims to shorten product development cycles by adopting build-measure-learn feedback loop from the lean startup methodology.Thus, developers have been allowed to run minimal viable products on-chain.\n\n> Demand Oriented Business Scenario: With the help of the decentralized ledger and advanced cryptographic protected private key of the QuarkChain Network it is believed that there can be DApps to support small business owners by providing an affordable and easy handling anti-counterfeit solution. This solution can also be used for education systems for validating diplomas and laboratory raw data.\n\n> The QuarkChain Network for Internet of Things: The QuarkChain Network will play an important role as a platform to support IoT applications with a large number of low-cost devices and speedy transactions.\n\n> The QuarkChain Network for AI and Big Data: Blockchain provides a digital platform for economic transactions and thus it is highly related to artificial intelligence (Al). Besides, QuarkChain Network offers reshardable functionality to reduce the transaction cost.\n\nAs blockchain grows, the amount of data increases fast .These data will generate great value for the company or the whole world’ s economy. The\nQuarkChain Network is open to collaborate with data analysts and economists to develop new economic models to further enhance the design of the QuarkChain Network with higher efficiency.\n\nMain features of QuarkChain at a glance:\n\n> Reshardable two-layered blockchain: QuarkChain consists of two layers of blockchains. Elastic sharding blockchains (shards) are applied as the first layer, and a root blockchain as the second layer that confirms the blocks from the first layer.The first layer is flexible to be resharded as needed without changing the root layer.\n\n> Guaranteed security by market-driven collaborative mining: To ensure the security of all transactions, a game-theoretic framework is designed for incentives, where at least 50% of overall hash powers are allocated to the root chain to prevent double spending attack on any transactions.\n\n> Anti-centralized horizontal scalability: In any blockchain network with a high TPS, a super-full node can be extremely expensive, which encourages centralization. In contrast, QuarkChain allows multiple cheap nodes forming a cluster to replace a super-full node.\n\n> Efficient cross-shard transactions: Cross-shard transactions in QuarkChain can be issued at any time, and confirmed in minutes. The speed of cross-shard transactions increases linearly as the number of shards increases.\n\n> Simple account management: There is only one account needed for the entire blockchains (shards) in QuarkChain. All cryptocurrencies from different shards are stored in one smart wallet.\n\n> Turing-complete smart contract platform: The QuarkChain network supports Turing-complete smart contracts and has adopted the Ethereum Virtual Machine (EVM) to allow for easy migration of existing EVM decentralized Apps onto the QuarkChain platform.\n\nQuarkChain VS Zilliqa:\n\nQuarkChain and Zilliqa are the only projects with sharding on testnet implementation and here are the differences:\n1. Zilliqa does not support turing-complete smart contract, while QuarkChain supports turing-complete such as EVM.\n2. Zilliqa only supports network sharding, while QuarkChain supports network and state sharding.\n3. QuarkChain has scalable cross-shard transaction, while Zilliqa’s cross-shard transaction is pretty limited.\n\nConclusion: Quarkchain is backed by a strong and experienced team that has the ability to execute the project successfully. QuarkChain could be one of the most successful projects of 2018 and has the capability to play vital role in crpyto world in the years ahead.\n\nFor more information, you may visit the following links:\n\nWebsite: https://quarkchain.io/\n\nTelegram: https://t.me/quarkchainio\n\nMedium: https://medium.com/@quarkchainquark\n\nFacebook: https://www.facebook.com/quarkchain.io\n\nTwitter: https://twitter.com/Quark_Chain",
