A new block generation method based on threshold digital signature

Abstract

The invention relates to a new block generation method based on the consensus of threshold digital signature, a block generates a candidate obtaining signature key algorithm, public and private keys and authentication data, if the transaction data is received and valid, it is placed into the transaction buffer, if the block generation condition is satisfied, a hash value (img file= 'DDA0001744553120000011. TIF' wi= '31' he= '63' / ) and signature sigma i are obtained and broadcast, after the block generation candidate receives sigma i and (img file= 'DDA0001744553120000012. TIF' wi= '40' he= '63' / ) from the remaining blocks, Valid signatures verifying sigma i as (img file= 'DDA0001744553120000013. TIF' wi= '35' he= '65' / ) are reserved, If the valid sigma i is equal to the threshold number and (img file = 'DDA0001744553120000014. TIF' wi= '37' he= '59' / ) is consistent, the final signature is synthesized, a new block is generated and broadcast. The invention adopts signature technology based on threshold digit, a consensus is reached among the block generation candidates on the new block. The invention ensures the normal operation of the block chain, reduces the generation and confirmation time of new blocks, avoids the risk caused by the failure of a candidate generated by one or several blocks, and has no single point of failure. As long as the candidates with a threshold numberstill operate normally, the new blocks can be generated, and a round of communication can reach the consensus of the new blocks.

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
