Blockchain is the technology behind cryptocurrency like Bitcoin. However, many other applications also claim to be disrupted by blockchain, including healthcare, insurance, Internet of Things, etc. In this talk, I will present the minimal background of blockchain that helps one to judge whether an application really needs blockchain or not. Furthermore, I will present some research opportunities of blockchain in terms of (i) distributed systems, (ii) security, (iii) database, and (iv) economic. Lastly, I will present one of my new research projects on blockchain.
