Blockchain, as a distributed ledger and decentralized database, has the potential to form a secured system of value exchange. Due to its attractive features, blockchain has drawn a lot of attention. As the pioneer of blockchain, Bitcoin has been implemented for more than a decade, and it reflects high levels of stability and reliability. It is foreseeable that blockchain will be implemented and applied to daily activities among institutions, businesses, and personnel. We conduct a study consisting of operating mechanisms, core technologies, research directions, applications, and drawbacks. This paper links that research to blockchain-based information systems.
