ABSTRACT
Blockchain, as a decentralized platform and distributed ledger database, will promote the centralized system to form a comprehensive ecosystem. A systematic review of blockchain research on information systems during the five-year period from 2016 to 2020 selected 46 papers from 16 leading journals. This paper introduces the technological characteristics and implementation models, highlighting its research status and development. Moreover, this paper illustrates the future research directions for blockchain. The objective of this paper is to discuss the emerging technology of blockchain in its early development stage and to depict the relevant IS issues that are worthy of further investigation.
