A New Block Generation Method Based on Threshold Digital Signature Consensus

Abstract

The present invention relates to a new block generation method based on threshold digital signature consensus. Block generation candidates obtain signature key algorithm, public key, private key and verification data. After receiving the transaction data, they are valid and put into the transaction buffer. If the block generation condition is met, sign it, get and broadcast the hash value and signature σ i , the block generation candidate receives the σ transmitted by the rest of the blocks i And later, verify σ i The effective signature for is reserved, and the effective σ i If the number is equal to and consistent with the threshold, the final signature will be synthesized, and a new block will be generated and broadcast. The present invention uses the signature technology based on the threshold number to reach a consensus on the new block among the block generation candidates, to ensure the normal operation of the block chain, to reduce the generation and confirmation time of new blocks, and to avoid generating candidates due to one or several blocks There is no single point of failure. As long as there are still a threshold number of candidates running normally, a new block can be generated, and a consensus on the new block can be reached in one round of communication.

Description

technical field [0001] The present invention relates to the technical field of payment architecture, scheme or protocol, in particular to a consensus new block based on a threshold digital signature that reduces the time for generation and confirmation of a new block and effectively avoids the risks caused by the failure of block generation candidates generate method. Background technique [0002] Blockchain, essentially a decentralized database, is a series of data blocks associated with cryptographic methods. Each data block contains the information of a transaction, which is used to verify the validity of its information (anti-counterfeiting ) and generate the next block. [0003] With the development of blockchain technology, there are more and more applications based on blockchain, but the transaction confirmation speed and throughput in blockchain have been criticized. [0004] In the existing technology, the consensus mechanisms with higher throughput and shorter co...

Problems solved by technology

[0004] In the existing technology, the consensus mechanisms with higher throughput and shorter confirmation speed in blockchain technology mainly include central node mode and committee mode. However, these modes have the disadvantages of single point failure or multiple rounds of communication
