Abstract: Blockchain technology is currently receiving increasing attention with widely used in many fields such as finance, retail, Internet of Things, and intelligent manufacturing. Although many blockchain applications are still in the early stage, this technique is very promising and has great potential. Blockchain is considered as one of the core technologies to trigger a new round of disruptive changes after Internet. In the future, it is expected to change the development prospects of many industries. However, the current blockchain systems suffer from poor performance which affects large-scale application. In order to better understand the performance of the blockchain systems, in this paper, we analyze four mainstream blockchain systems (Ethereum, Fabric, Sawtooth and Fisco-Bcos), and then perform a performance comparison through open source blockchain benchmarking tools. After that, we propose several optimization methods and discuss the future development of blockchain technique.
