QuarkChain (QKC) is a blockchain platform designed to improve scalability and efficiency. It uses a unique two-layer architecture. The first layer is made up of multiple chains that can handle transactions in parallel, while the second layer is responsible for consensus and security. This structure allows QuarkChain to process thousands of transactions per second.One of its main features is sharding. Sharding divides the network into smaller, manageable segments that can operate independently. This reduces the load on any single chain and enhances overall network performance.QuarkChain also focuses on user experience and aims to make transactions faster and cheaper. The platform supports smart contracts, enabling developers to build decentralized applications (dApps) that can leverage its high transaction capacity.The native token, QKC, is used for various purposes within the ecosystem, including transaction fees and staking for network security. Overall, QuarkChain aims to provide a scalable solution for blockchain applications, addressing the challenges of speed and efficiency commonly faced by many existing platforms.
