The QuarkChain Network is a permissionless blockchain architecture designed to meet global commercial standards. It offers flexibility, scalability, decentralization, and great usability. It supports multiple consensuses, transaction models, ledgers, and token economics in one network, and can adapt to blockchain innovations. The network is EVM-compatible and plans to add more virtual machines in different shards. QuarkChain has achieved 55000+ peak TPS in a TPS competition, and its two-layered structure encourages individual miners to mine directly without joining pools.
