Blockchain consensus method and device

Abstract

The invention relates to a blockchain consensus method. The method comprises the steps that a production node in a blockchain network generates a to-be-confirmed block according to transaction data; the production node broadcasts the to-be-confirmed block to a signature node; the signature node carries out digital signature on the to-be-confirmed block by using a private key based on a primary voting principle, and the primary voting principle is that when the signature node receives a plurality of to-be-confirmed blocks at the same block height, only the received first to-be-confirmed block is digitally signed; the signature node sends the digital signature to the production node; and the production node generates a to-be-valid block according to the digital signature, adds the to-be-valid block to a self-stored block chain, and broadcasts a chain above the to-be-valid block. The blockchain consensus method uses one node and one ticket, meaningless hash is not needed, monopoly type overall control of large computing power and large stock rights is also eradicated, the cold start problem of new nodes is solved, meanwhile, the block production frequency of each node is controlled, and therefore part of nodes are prevented from being cut alone for a long time.

Description

technical field [0001] One or more embodiments of this specification relate to Internet information processing, and in particular to a parliamentary system-based consortium block chain consensus method and device. Background technique [0002] At present, common blockchain consensus algorithms generally have the following types: the proof of work method (proof of work) used by BTC, which uses the computing power of nodes to determine the right to produce new blocks, and at the same time increases the cost of attacks; PPC The proof of stake method used, which measures the right to generate new blocks by the age of the coin; the delegated proof of stake method used by BitShares, which, on the basis of the proof of stake method, will produce equity Delegate to designated agents, thereby reducing the number of nodes producing blocks. [0003] The blockchain is divided into three types according to the degree of openness of the participants, namely, public chain, alliance chain,...

AI Technical Summary

Problems solved by technology

The proof of equity method still relies on the coin issuance process. The production authority of each node is controlled by the existing coin age. New nodes cannot quickly participate in it, and it is easy for malicious nodes to hoard a large number of coin age to attack the long chain.
