A Prototype System for Blockchain Performance Evaluation.

Due to complex blockchain programs and numerous blockchain nodes, it takes a huge amount of time and economic cost to conduct blockchain experiments. Existing open source projects do not support modifications to the underlying blockchain, and existing blockchain simulators only focus on a single blockchain system and cannot flexibly extend or replace models. Regarding the issues above, this paper proposes a prototype system for blockchain performance evaluation, including real deployment test and simulation test. In real deployment test, a five-layer architecture for building a lightweight and efficient testing system is proposed. And in simulation test, a general scheme for building blockchain simulator is proposed, which can realize the test of throughput, storage allocation and reputation management. Experiments show that the prototype system proposed in this paper can effectively improve the efficiency of blockchain performance evaluation.
