QKC QuarkChain Rank #950

QuarkChain (QKC) is a decentralized, permissionless blockchain platform designed to address scalability limitations affecting major networks. It employs sharding technology with the aim of delivering very high transaction throughput, positioning itself as a peer-to-peer system capable of supporting fast and secure decentralized applications. The architecture relies on a two-layer structure: a first layer composed of sharded blockchains that process transactions in parallel, and a second root blockchain that confirms and finalizes the blocks produced by those shards. To encourage broader participation, QuarkChain allows clusters of inexpensive nodes to operate collectively as a super-full node, reducing the hardware costs typically associated with running high-capacity infrastructure. Security is reinforced by guaranteeing that transactions are protected by a substantial share of the network's hash power, making double-spend attacks difficult to execute. Development of QuarkChain began in 2017 with research into scalability, followed by a whitepaper and early testnet releases in 2018. The QKC token functions within the Ethereum ecosystem and also integrates with the Energi ecosystem, serving utility roles across the network.
