QuarkChain (QKC) is a permissionless blockchain architecture that seeks to meet global commercial standards. It aims to provide a decentralized and scalable blockchain solution with the potential to support a high number of on-chain transactions per second (TPS). QuarkChain is a public chain that can support multiple consensuses, transaction models, ledgers, and token economics in one network. It is designed to adapt to blockchain innovations by customizing these elements in each shard to satisfy different requirements of various industries, enterprises, and DApps. The network supports two consensus algorithms, PoW and PoSW (a combination of PoS+ PoW), and is EVM-compatible, meaning every DApp deployed on Ethereum can also be deployed on QuarkChain.

QuarkChain operates on a two-layered structure and encourages individual miners with different levels of capability to mine directly without joining mining pools. People can choose to mine either in the root chain or in the shard. QuarkChain supports Native token which enables each shard to have its own token economics. It also supports scalable cross-shard transactions. Only one account is required to access entire resources in all shards, and smart wallets simplify the management. QuarkChain aims to support a high number of on-chain transactions per second (TPS) and has already reached a peak of 55,000+ TPS in a competition held within the community.

QuarkChain has a wide range of potential use cases across various industries. It can be used by enterprises and developers to build decentralized applications (DApps) that require high scalability and security. The network's support for multiple consensuses, transaction models, ledgers, and token economics makes it adaptable to different industry requirements. Furthermore, QuarkChain's support for Native token enables each shard to have its own token economics, which can be leveraged for various use cases within the respective shard.

QuarkChain was launched on June 2, 2018, with the aim of providing a decentralized and scalable blockchain solution. The project has been focused on enhancing the scalability of blockchain technology by applying blockchain sharding technology. Over time, QuarkChain has reached certain milestones, including the achievement of 55,000+ peak TPS in a competition held within the community. The project has also launched its Mainnet 2.0 BigBang, which supports multi-native token function. QuarkChain continues to adapt to changes in the blockchain landscape.
