Latency Analysis for Raft Consensus on Hyperledger Fabric

Abstract

AbstractAs a permissioned blockchain system, Hyperledger Fabric is getting increasing attention from enterprises, however, the current Hyperledger Fabric system is difficult to meet the real-time application requirements of enterprises. This paper focus on the Raft consensus latency that is time consumption of consensus, we provide a theoretical model of the Raft consensus latency. Subsequently, we analyze the effect of consensus latency on the transaction latency and the effect of a block size on consensus latency by extensive experiments. The experimental result shows that the proportion of consensus latency in the entire transaction latency is relatively small, while the block size has more greater effect on the consensus latency.KeywordsBlockchainRaft consensusConsensus latencyTransaction latencyHyperledger fabric
