A P2P Surplus Energy Trade Among Neighbors Based on Hyperledger Fabric Blockchain

Abstract

We propose a Hyperledger Fabric blockchain based P2P surplus energy trade system in which participating prosumers and consumers trade surplus energy with high reliability and scalability. Previous POW (Proof-of-Work)-based blockchain such as public Ethereum may cause low throughput and long latency due to their probabilistic consensus algorithm which does not guarantee real-time. We choose Hyperledger Fabric blockchain because its consensus mechanism may be divided into individual phases (Endorsement, Ordering and Validation), which is eligible for speed up through parallel processing. We illustrate how to build an energy trade system using Hyperledger Fabric with set up of endorsing peers, orderers and validating peers. We also show how to protect the system from possible attackers by set up of CA (certificate authority) and MSP (membership service provider) in IBM Blockchain Platform.
