The QuarkChain Network represents a permissionless blockchain architecture designed to adhere to global commercial standards. Its objective is to furnish a secure, decentralized, and scalable blockchain solution capable of supporting over 100,000 on-chain transactions per second (TPS). Key features of the QuarkChain Network include: Flexibility: QuarkChain operates as a public chain that accommodates multiple consensuses, transaction models (including virtual machines VMs), ledgers, and token economics within a single network. This adaptability allows it to tailor consensus, transaction models (including VM), ledger, and token economics in each shard to meet the diverse requirements of various industries, enterprises, and DApps. The network currently supports two consensus algorithms, PoW and PoSW (a combination of PoS+ PoW), with plans to incorporate more consensus algorithms (such as DPoS, PoS, etc.) into different shards in the future. Additionally, it is EVM-compatible, enabling DApps deployed on Ethereum to be seamlessly deployed on QuarkChain. Scalability: QuarkChain aims to achieve a throughput of over 100,000 on-chain TPS. Notably, it has already achieved over 55,000 peak TPS in a competition held within the community. Decentralization: The QuarkChain network features a two-layered structure that encourages individual miners with varying capabilities to mine directly without joining mining pools. Miners have the option to mine in either the root chain or in the shard, promoting decentralization. User-Friendliness: QuarkChain supports Native tokens, enabling each shard to possess its own token economics. It also facilitates scalable cross-shard transactions. Users require only one account to access resources across all shards, and smart wallets simplify management tasks.
