Research and application of hyperledger fabric based on VRF on electronic order

Abstract

Abstract With the rapid development of information digitization, a large number of electronic orders have also brought a series of problems such as data security and trust. In the face of the ever-increasing demand for electronic data storage, the traditional and conventional storage methods have gradually exposed many problems such as extremely high cost, low efficiency, and difficulty in acceptance. It has become an urgent need to ensure the data security and credibility of electronic orders. solved problem. Aiming at how to ensure the authority and security of electronic documents, through the study of the Hyperledger Fabric consensus mechanism, and at the same time, in order to solve the security risks and processing bottlenecks caused by the use of fixed endorsement nodes in the hyperledger structure to handle all exchanges, the use of A non-interactive, verifiable random endorsement scheme. On the basis of the consensus mechanism of endorsement-sorting-verification, by introducing a candidate set of endorsing nodes, using a verifiable random function to randomly select endorsing nodes and endorsing each order, a non-interactive verifiable random selection of endorsing nodes is realized And parallel endorsement process. Analysis and experiments show that the optimized consensus mechanism has higher security and faster transaction processing speed.
