A Scalable and Extensible Blockchain Architecture

Abstract

It has been a long time since Nakamoto Satoshi introduced Bitcoin [1]. However, the underlying technology, blockchain, has been getting more and more attention. It is regarded as one of the most important technology for the fourth industrial revolution, although there exit few the real-world production-level applications due to the hardly tolerant performance of most of the existing blockchain systems. Therefore, how to improve its performance has been identified as one of the most significant research directions in order to use blockchain for practical applications. In this paper, we present a method to build a scalable and extendible blockchain system by multiple chains and sharding techniques.
