Embodiment Construction

[0041] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them.

[0042] This application provides a blockchain consensus verification method, including:

[0043] S101. Network communication is established between each node of the block chain, and private data is exchanged through the network communication, and the private data matches the communication node and the communication direction;

[0044] For example, when network communication is established between node A and node B in the blockchain, node A will send private data to node B, and node B will also send private data to node A. However, the private data se...

Abstract

The invention provides a blockchain consensus verification method. The blockchain consensus verification method comprises the following steps: a, exchanging private data between nodes of a blockchainthrough network communication; b, any node in the blockchain performing consensus on the transaction and signing consensus information; c, performing hash calculation on the signature and the consensus information by any node to obtain a hash value H; d, sending the hash value H to other nodes in the blockchain by any node; e, performing hash calculation on the other nodes to obtain a hash value H'; f, the other nodes verifying whether the received hash value H is equal to the hash value H' obtained through calculation or not, and if yes, passing the verification. HASH (hash) operation is adopted to replace an elliptic curve signature and signature verification algorithm, huge computing power consumption caused by the elliptic curve algorithm is avoided, and the blockchain consensus verification efficiency is improved.

Description

technical field [0001] This application relates to the technical field of block chain, in particular, relates to a block chain consensus verification method. Background technique [0002] At present, the common consensus confirmation algorithm of the blockchain adopts the elliptic curve signature and unsignature algorithm, and the producer's signature and consensus need to be sent to the verification producer together. The verification producer needs to unsign the signature, and the elliptic curve signature and unsigning algorithm requires a lot of computing power to be consumed in the consensus verification process. For example: three nodes A, B, and C in the blockchain need to agree on transaction T. [0003] First, node A performs a consensus signature sig-A on transaction T and sends it to nodes B and C; [0004] Nodes B and C unsign the signature sig-A and verify the consensus information; [0005] Node B performs a consensus signature sig-B on transaction T, and sen...
