An Overview and Current Status of Blockchain Simulators

Abstract

Since the introduction of Bitcoin, blockchain has attracted tremendous interest from both academia and industry. During the last decade, various large-scale blockchain systems were developed. However, the complexity of large-scale distributed systems makes the performance evaluation process challenging and costly. Here, blockchain simulators give the possibility to repeat complex real-world processes at a low cost. Simulators are easily extensible and can test distributed ledger performance using different settings and parameter variations. This work reviews and summarizes the current status of the state-of-the-art blockchain simulators.
