SCT (SuperConductToken, superconducting chain) is a decentralized application platform with an isomorphic multi-chain architecture (1+N multi-chain, that is, a main chain and N alliance chains for parallel computing), serving all business enterprises Transaction circulation, resource integration and optimization. The main chain adopts Pow+pos consensus algorithm, Pow eliminates the monopoly of computing power, Pos generates currency holding income, and optimizes the superconducting economic ecology; alliance chain uses Pbft, Raft, Ldpos consensus algorithm to improve business processing capabilities, multi-service alliance chain parallel computing, support High concurrency, millisecond-level confirmation of transactions in the business chain, dozens of times the concurrency capability of the public chain.
