The blockchain architecture with distributed and decentralized as the main features often face problems such as long transaction confirmation time, low system throughput, and waste of computing resources. These problems are exactly what the traditional centralized architecture can solve. At the same time, in order to improve the distributed consensus efficiency, consensus algorithms such as Proof of stake, delegated proof of stake, proof of space, proof of authority, and PBFT have emerged from Bitcoin's Pow consensus mechanism. These consensus algorithms have their own advantages and Disadvantages. Disadvantages, such as Pos, DPos can improve transaction efficiency, PBFT can improve the fairness of voting, but at the same time POS also bring benefits and voting rights to hold a lot of user tilt issues to a small number of tokens, PBFT brings about a low cost of malicious user attacks and other issues. In order to effectively take advantage of the high security, high reliability of the blockchain, and high efficiency of traditional centralized architectures, and fully utilizing existing consensus mechanisms, this paper presents an innovative hybrid blockchain approach, which mixed the blockchain architecture, Hybrid-chain, consists of the following three type nodes in the architecture: service center nodes responsible for efficient transaction confirmation, dynamic transaction verification nodes participating in transactions, and random verification nodes responsible for transaction fairness verification. On the consensus mechanism, the consensus algorithm selects the corresponding consensus mechanism according to the transaction characteristics. Experiments show that compared with the traditional blockchain architecture, hybrid chain has obvious performance advantages in transaction sending, transaction confirmation and block information storage, which can greatly reduce the transaction sending time by 96%, shorten the confirmation time by 95%, and reduce the number of 79.% Block information storage space, etc.
