Scheme for improving RAFT-based blockchain performance

Abstract

Improving RAFT-based blockchain systems' performance and their relationship with environmental factors is a lack of concern in recent studies and is essential in the production environment. To attain this, it is necessary to analyze the performance, especially the blockchain system's throughput, latency, and robustness. The two most widely used RAFT-based platforms, etcd, and Hyperledger Fabric's evaluation, were conducted to discover the factors influencing the system's performance and promoting methods. The evaluation focused mainly on throughput, latency, and robustness, including evaluating the reading and writing process, changing the number of keys, connections, and clients in etcd, and comparing the process and the two platforms. The only number of clients significantly impacts etcd's performance, and etcd's performance is better than Hyperledger Fabric's. Besides, both two platform shows that reading performs better than writing. So, to improve the system's performance, controlling the number of clients and focusing on the writing process is the key.
