Method and system for establishing block consensus in blockchain

Abstract

The invention discloses a method and system for establishing a block consensus in a block chain. In the invention, mining nodes carry out packaging on transaction information in respective transaction pits according to a preset block format; after a plurality of blocks are obtained, overall contents or partial contents of the plurality of blocks are subjected to signature processing to obtain signature messages, and a plurality of blocks and a plurality of signature messages are broadcasted to a block chain network; complete nodes and the mining nodes respectively carry out hash processing on the monitored overall contents or partial contents of the plurality of blocks to obtain a plurality of second hash values, and the plurality of second hash values are compared with a plurality of first hash values to obtain signature information corresponding to each second hash value; and a plurality of pieces of signature information is subjected to numeralization processing, one value is selected from a plurality of values according to a preset selection mechanism, and a block corresponding to the signature information corresponding to the value is assembled to the block chain. A load of the mining nodes is reduced, and meanwhile, checking workload generated when the blocks are assembled to the block chain is also reduced.

Description

technical field [0001] The present invention relates to the field of Internet technology, in particular to a block consensus establishment method and system in a block chain. Background technique [0002] All traditional payment systems rely on a central certification authority, relying on the settlement services provided by the central authority to verify and process all transactions. The blockchain has no central authority, and almost all full nodes have a backup of the public ledger, which can be considered a certified record. [0003] The blockchain is not created by a central organization, it is completed independently by all nodes in the blockchain network. All nodes in the blockchain network, relying on the information transmitted by the unstable network connection between nodes, finally reach the same result and maintain the same public ledger. In other words, consensus is the product of thousands of independent nodes spontaneously forming through asynchronous inte...

Problems solved by technology

[0005] Among them, the verification of the proof-of-work algorithm independently completed by the mining node is referred to as the proof of computing power. This kind of proof of computing power will consume a large amount of computer resources, making the verification workload undertaken by the mining node very large, which seriously increases the workload of the mining node. burden, and the process of independently verifying new blocks by mining nodes and full nodes is relatively complicated. The existing technology lacks a technical solution that simplifies the amount of calculation and quickly assembles blocks into the blockchain
