[Objective] This paper examines the key technologies and major issues of high-performance blockchain, and then explores its research trend and future development. [Coverage] We searched “Consensus Algorithm”, “Smart Contract”, and “Blockchain” in Chinese and English with Web of Science, Google Scholar, CNKI and other Internet resources. A total of 39 documents were selected for this review. [Methods] We summarized the evolution of consensus algorithm, as well as the advantages and disadvantages of smart contract applications or platforms. [Results] This study discussed the key issues and methods of the consensus algorithm and smart contracts for high-performance blockchain. [Limitations] We only reviewed the representative consensus algorithms and implementation platforms. [Conclusions] This paper summarizes the technologies of high-performance blockchain and provides ideas for the future research.
