QuarkChain is a blockchain infrastructure company that utilizes blockchain sharding technology to create a flexible, scalable, and user-oriented platform. It offers features such as multi-VMs, multi-consensuses, multi-ledgers, and cross-shard transactions. QuarkChain also supports the development of decentralized applications and provides an ecosystem with numerous partner projects.
QuarkChain aims to build a high throughput blockchain targeting 10,000 transactions per second. To accomplish this the team is building a multi-layer blockchain that leverages sharding. It runs using the Ethereum Virtual Machine and like Ethereum targets general purpose smart contract applications. Currently, the project uses a placeholder ERC-20 token and will complete a token swap during a planned mainnet launch in late 2019.
