Performance Analysis on Block Size Valuation of Hyperledger Fabric Blockchain

Blockchain is an innovative technology and a decentralized ledger of immutable digital data. Hyperledger Fabric (HLF) blockchain is a permissioned ledger framework. The Fabric is made up of different parts, including endorsers, committers, validators, orderers and chaincodes. Although HLF is a scalable modular architecture, the configuration parameters of block size valuation in the orderer section impact the performance of a blockchain-based system. The ratio of batch timeout and block size should be balanced to increase the system performance. The block size valuation also affects the committed block height in the blockchain. In this paper, the effect of configuration factors such as batch timeout and block size (batch size) is analyzed to implement the optimizing blockchain-based storage system. Hyperledger Caliper tool is used to measure the transaction throughput and average latency for the system performance. The block height are studied based on the different batch timeout and block sizes for the numbers of concurrent users in an organization.
