QuarkChain
QuarkChain is a secure, permissionless, scalable, and decentralized blockchain. One of QuarkChain's goals is to use sharding technology to deliver over 1 million transactions per second (tps). Essentially, QuarkChain positions itself as a peer-to-peer blockchain with high throughput capacity to support fast and secure decentralized applications. The team behind QuarkChain created this blockchain to address the scalability issues currently faced by all major blockchains. The team believes that, due to the urgency of this issue, the Bitcoin community cannot afford to wait until consensus is reached on a solution. Instead, it believes that offering different solutions, such as the one inherent in QuarkChain, compels the community to split via a hard fork and find the solution that works best. QuarkChain promotes greater decentralization through multiple low-cost nodes that form a cluster functioning as a super-full node. This avoids the high costs associated with super-full nodes when tps is high. In terms of security, all transactions within QuarkChain are protected by 50 percent of the network's hash power. This makes a double-spending attack extremely difficult, particularly when combined with QuarkChain's decentralized nature. QuarkChain relies on a two-layer blockchain structure. Sharding blockchains known as shards form the first layer, while the second layer is a root blockchain that confirms the shards' blocks. Major work on QuarkChain began in Q2 2017 with research into blockchain scalability. In Q4 of that year, the team drafted the whitepaper. In February 2018, it released the white paper and completed verification code 0.1. In March 2018, version 0.1 of both the wallet and testnet was released. In Q2, the team is working on testnet 1.0 and smart contract 0.1. In Q4 2018, the team will have QuarkChain Core 1.0, mainnet 1.0, and SmartWallet 1.0. By Q2 2019, both SmartWallet and QuarkChain Core will be at version 2.0. QuarkChain is a decentralized blockchain network that aims to address the scalability issues affecting existing networks through sharding technology. In this way, QuarkChain can significantly extend the usefulness of blockchain technology, as many applications are constrained by the scalability of existing blockchain networks. The project remains in progress, but QuarkChain has already made many positive steps and has begun invite-based beta testing for the testnet, demonstrating significant progress and potential. The main features of QuarkChain are: 1. Reshardable two-layer blockchain: QuarkChain consists of two layers of blockchains. Elastic sharding blockchains (shards) are used as the first layer, and a root blockchain serves as the second layer, confirming blocks from the first layer. The second layer confirms blocks from the first layer. The second layer can be resharded as needed without changing the root layer. 2. Guaranteed security through market-driven collaborative mining: To ensure the security of all transactions, a game-theoretic incentive framework is designed in which at least 50% of overall hash power is allocated to the root chain to prevent double-spending attacks on any transactions. 3. Anti-centralization horizontal scalability: In any blockchain network with high TPS, a super-full node can be extremely expensive, which encourages centralization. In contrast, QuarkChain allows multiple low-cost nodes to form a cluster that replaces a super-full node. 4. Efficient cross-shard transactions: Cross-shard transactions in QuarkChain can be issued at any time and confirmed within minutes. The speed of cross-shard transactions increases linearly as the number of shards increases. 5. Simple account management: Only one account is required for the entire blockchain (shards) in QuarkChain. All cryptocurrencies from different shards are stored in one smart wallet.
