Game blockchain consensus method based on bilinear mapping algorithm and set signature algorithm

Abstract

The present invention relates to a game blockchain consensus method based on a bilinear mapping algorithm and a set signature algorithm. The method comprises the steps of: broadcasting transaction data to a whole network through any node, and attaching signature of a sender to the transaction data; after a set node receives m messages without insertion, employing a set signature algorithm and a bilinear mapping algorithm to perform operation of the m messages to obtain a set signature, and sending the set signature in the round of consensus time; receiving set signature information with a given quantity by the any node in the network to reach a consensus and publish a whole block; and deleting the included transaction from the memory after any node receives the whole block, and starting the next round of consensus. The game blockchain consensus method based on the bilinear mapping algorithm and the set signature algorithm can aggregate the signatures of the m original messages into onesignature to reduce the confirmed consumption of the message transmission and allow the space complexity to be reduced to 1 / m of the original space complexity so as to improve the transaction processing efficiency and increase the network capacity.

Problems solved by technology

[0007] At present, the main challenge facing the consensus algorithm on the blockchain is the efficiency of the consensus process, which is affected by the number of transactions, transaction frequency, and transaction processing efficiency requirements. The efficiency of the consensus algorithm is one of the constraints that restrict the application of blockchain technology. Therefore, it is particularly important to optimize the consensus algorithm on the blockchain

At present, the transaction throughput of Bitcoin is 7TPS, and the transaction throughput of Ethereum is 20-30TPS. The transaction confirmation time takes several minutes or even hours. Compared with game applications, the number of game users is large and transactions are frequent. The classic blockchain consensus The algorithm is difficult to meet the application requirements, so it is necessary to design a suitable and efficient consensus algorithm according to the characteristics of the game to improve transaction processing capabilities
