Detailed description

QuarkChain is an innovative permissionless blockchain architecture that aims to meet the global-wise commercial standard. It provides a secure, decentralizid, and scalable blockchain solution to deliver 1,000,000+ on-chain TPS. The main idea of QuarkChain was inspired by our extensive experience in developing powerful large-scale distributed systems in centralized world that handles billions of TPS. The team manages to apply the technologies on blockchain to create the uique solution on blockchain scalability problem. The solution aims to largely the boundaries of blockchain usabiluty without damaging its safety and decentralization features. 


Bitcoin community meets the problem of scalability (blockchain only offers around 4 TPS) that usually sacrifices decentralization and security.  Different solutions compel the community to split through a controversial hard fork.


QuarkChain aims to deliver hundreds of thousands or millions of transactions per second in a few years (from 10K TPS to 1M TPS).


  • Reshardable two-layered blockchain: QuarkChain consists of two layers of blockchains. We apply elastic sharding blockchains (shards) as the first layer, and a root blockchain as the second layer that confirms the blocks from the first layer. The second layer is flexible to be resharded as needed without changing root layer.
  • 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.
  • 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.
  • 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.
  • 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.
