Message from the Blockchain 2020 Program Chairs

Abstract

As a promising technique to achieve decentralized consensus, blockchain has been successfully applied to digital currencies such as 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. 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, privacy, efficiency, flexibility, availability and high dependability. In this manner, blockchain holds great potential to create new foundations for our socio-economic systems by efficiently establishing trust among people and machines, reducing cost, and improving speed and efficiencies of transactions.
