A Trusted Solution to Hyperledger Fabric Reordering Problem

Hyperledger Fabric consortium chain is a more reliable blockchain between members, which is widely used in a variety of applications due to its imtamperability. Fabric++ proposes optimization strategies to improve the efficiency of Hyperledger Fabric, but this leads to a decline in its credibility. In the end, we propose solutions to the fairness, stability, and availability issues of Fabric++ in terms of trust, as well as the possible impact. In our paper, we build a simulation system based on gPRC communication and verify the correctness of our solutions. Further, we implement the solution of FabricUp based on Hyperledger Fabric V2.2 and conduct a series of experiments. The experimental results show that FabricUp effectively solves the credibility problem in Fabric++.
