Verification based blockchain common recognition method

Abstract

The invention relates to a verification based blockchain common recognition method. A client sends a request message to a verification initiation node; the verification initiation node organizes a pre-preparation message and broadcasts the message to other verification nodes in the network; the other verification nodes organize signature messages and return the signature messages to the verification initiation node respectively; the verification initiation node counts the signature messages which are received correctly, submission of the present node is executed when the number of the signature messages which are received correctly reaches a given threshold, and a verification message is organized and sent to the other verification nodes; each of the other verification nodes checks digitalsignatures in the message successively, when the number of the digital signature that passing checking reaches a given threshold, submission operation of the present node is executed, and a verification reply message is organized and returned to the verification initiation node; and the verification initiation nodes organizes a response message and back feeds the response message to the client. Compared with a practical Byzantine fault tolerant method, the network communication frequency and communication data bulk are reduced, and the common recognition efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a verification-based block chain consensus method. Background technique [0002] Blockchain is a decentralized distributed database technology with the participation of various nodes, which has the characteristics of complete traceability, decentralization and de-credit. The blockchain does not have a central organization, and the consistency of the information of each node is guaranteed through the consensus mechanism of the blockchain. The blockchain consensus mechanism is based on the Byzantine fault-tolerant distributed consensus algorithm and a communication model for transmitting and synchronizing data according to specific business scenarios. The consensus algorithm is one of the core technologies of the blockchain, and the performance of the algorithm directly affects the effectiveness of the system. [0003] Currently common consensus algorithms include workload p...

Problems solved by technology

[0004] The Practical Byzantine Fault Tolerance Protocol is suitable for the consortium chain environment, but the consensus efficiency of network nodes is not high, especially when the number of network nodes increases, the number of network communications and the amount of communication data increase rapidly, and a targeted consensus algorithm needs to be designed to improve consensus efficiency and reduce network traffic
