Problems solved by technology

[0004] However, at present, the invalid transactions on the hyperledger are determined in the verification stage. When there are a large number of invalid transactions in the hyperledger, the throughput of the blockchain system will be affected, resulting in a decrease in the performance of the hyperledger.

Abstract

The invention relates to a transaction sorting method and device in a super account book and computer equipment. The method comprises the following steps: constructing a transaction conflict graph corresponding to a transaction set initiated at the same moment in a block chain; wherein each node in the transaction conflict graph represents a transaction; decomposing the transaction conflict graphthrough an algorithm for solving the strongly connected components of the directed graph to obtain a corresponding strongly connected graph set; marking the total frequency of each transaction in thetransaction set according to the strongly connected graph set; removing the node representing the transaction with the maximum total number of times from the transaction conflict graph, and updating the total number of times of occurrence of each transaction until no strong connection graph exists in the transaction conflict graph to obtain a conflict-free transaction graph; and based on the direction of each node in the conflict-free transaction graph, determining an execution sequence of effective transactions in the conflict-free transaction graph through sorting nodes of the super accountbook. Performance of the super account book can be improved.

Description

technical field [0001] The present application relates to the technical field of hyperledgers, in particular to a method, device, computer equipment and storage medium for ordering transactions in hyperledgers. Background technique [0002] Hyperledger Fabric (super ledger) is widely used in the construction of blockchain alliance chains. Its technical characteristics can make the update of data on the chain through the consensus mechanism through the algorithm of consensus and sorting nodes, ensuring the integrity of data in distributed systems. Consistency and security. [0003] In the hyperledger, a transaction needs to go through four stages from being initiated to being finally written into the ledger, which are simulated endorsement, sorting, verification and submission. In the simulation phase, the client generates transaction information, and sends the parameters corresponding to the transaction information to multiple endorsement nodes; in the endorsement phase, af...
