Abstract

The invention discloses a block chain multi-party consensus method based on a consistent hash algorithm, and the method comprises the steps: (1) formulating a multi-party consensus protocol, and solving a hash value of a node; (2) generating a block and a broadcast block according to the multi-party consensus protocol, and verifying and voting the generated blocks; (3) finding the position of a virtual node, on the hash ring, of the virtual node corresponding to the node according to the hash value; (4) selecting a main chain, synchronizing and broadcasting the blocks on the selected main chain, and storing the data of the nodes to the found virtual nodes; and (5) writing the synchronized and broadcasted blocks into a block chain. The invention discloses a block chain multi-party consensusmethod. On the basis of the non-rollback principle of the block chain, a consistent hash algorithm is adopted to realize load balancing in the consensus verification process, a Paxos and stock rightauthorization proving algorithm is improved, the consistency and non-tampering performance in the consensus process of the block chain are ensured, and the problem of network faults caused by malicious tampering is reduced.

Description

technical field [0001] The invention belongs to the field of block chain technology and consensus algorithm, and specifically relates to a block chain multi-party consensus method based on a consistent hash algorithm. Background technique [0002] Blockchain technology is a collection of new application models, including distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, smart contract, cross-chain and other technologies, and has the advantages of decentralization, trustlessness, and security. Through the chain composed of countless blocks, the blockchain forms a whole with a secure and transparent link whose performance far exceeds the simple sum of individuals, saving a lot of time and cost. With the development of the times, blockchain technology is becoming more and more important. In the process of applying blockchain to all walks of life in society, and even in the process of using it in different units of the same industr...
