As a promising technique to achieve decentralized consensus, blockchain has been successfully applied into digital currency, e.g., bitcoin, for serving as a public ledger for transactions. Its secure design for supporting a distributed computing system with high fault tolerance is attracting wide attention all over the world. Blockchain has a great potential to create new foundations for our socio-economic systems by efficiently establishing trust among people and machines, reducing cost, and increasing utilization of resources. On one hand, blockchain will play an important role for secure decentralization in such emerging fields as Internet of Things, Cyber Physical Systems, edge computing, social networking, crowdsourcing and next generation wireless communications, and even more other fields. On the other hand, its advance should be further evolved in terms of scalability, security, privacy, efficiency, flexibility, availability, real decentralization and high dependability.lars in the following aspects:
