Verification-Based Blockchain Consensus Approach

Abstract

The invention relates to a block chain consensus method based on verification. The client sends the request message to the verification initiating node; the verification initiating node organizes pre-prepared messages and broadcasts them to other verification nodes in the network; other verification nodes organize signed messages and returns them to the verification initiating node; the verification initiating node counts the number of signed messages correctly received, reaching When the threshold is given, the submission operation of the node is executed, and the verification message is broadcast to other verification nodes in the network; other verification nodes verify multiple digital signatures in the message in turn, and when the number of digital signatures that pass the verification reaches the given threshold, Execute the submit operation of this node, and organize the verification reply message to be returned to the verification initiating node; the verification initiating node organizes the response message to be fed back to the client. Compared with the practical Byzantine fault-tolerant consensus method, the present invention reduces the number of times of network communication and the amount of communication data, and improves the efficiency of consensus.

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
