Blockchain and Distributed System.

In recent years, blockchain technology has received more and more attention. Blockchain is a storage technology for public decentralized databases. The emergence of blockchain technology makes it possible to solve the trust problem of distributed system nodes within the wide area network. This article elaborated on the current advantages and disadvantages of blockchain technology and the main problems facing the development of wide-area distributed systems. This paper attempts to combine the ideas of blockchain and distributed system, and gives a complete design scheme of blockchain for building a wide area network distributed system. The designed blockchain not only retains the tamper-proof and traceable characteristics of the existing blockchain technology, but also can overcome the node trust problem of the wide-area distributed system.
