According to the method, high couplingof a consensus algorithm and a block chain system verification node is solved, a design idea of a pluggable consensus algorithm is provided, system consensus and intelligent contract decoupling are realized, the consensus algorithm is high in availability and easy to expand, and monitoring operation and maintenance of the consensus node are more convenient and controllable. Meanwhile, the problemthat the communication cost of the original PBFT algorithm is too high in a private chain environment is solved, and the communication complexity is reduced after the RAFT algorithm is used. The average response time of the block chain can be effectively reduced, the utilization rate of a CPU and a memory of a server is reduced, and the resource overhead is saved.

Description

technical field [0001] The present invention relates to the technical field of data interaction, and more specifically, to a blockchain data interaction method and device that can switch consensus algorithms. Background technique [0002] As an innovative technology architecture born with Bitcoin, blockchain technology is essentially an open, transparent, tamper-proof, and traceable distributed ledger technology. In blockchain technology, the consensus mechanism is a core component. The blockchain consensus mechanism describes the process of reaching a consensus on a certain state between multiple nodes in a distributed system. Its goal is to make all The methods and devices used by honest nodes to access containers preserve a consistent view of the blockchain. However, current blockchain products in the industry only support a single deeply embedded consensus algorithm. For example, Hyperledger Fabric only supports the PBFT algorithm, and Ethereum only supports the POW algo...

In blockchain technology, the consensus mechanism is a core component. The blockchain consensus mechanism describes the process of reaching a consensus on a certain state between multiple nodes in a distributed system. Its goal is to make all The methods and devices used by honest nodes to access containers preserve a consistent view of the blockchain. However, current blockchain products in the industry only support a single deeply embedded consensus algorithm. For example, Hyperledger Fabric only supports the PBFT algorithm, and Ethereum only supports the POW algorithm. The single consensus algorithm is difficult to apply to changing business scenarios, and has become a bottleneck restricting technology application and business promotion
