Exploring Blockchain Scalability using Sharding Techniques
Scalability has become a significant research topic of blockchains, since it is deemed as a bottleneck preventing blockchain technologies from being largely adopted. Several representative solutions have been proposed to improve the blockchain scalability. Especially, sharding technique is believed as a promising Layer1 solution. Although blockchain sharding can improve the throughput of blockchain systems significantly in theory, there are some typical challenges behind this technique. For example, i) the number of cross-shard transactions in a sharding system is overwhelming, ii) the atomicity of cross-shard transactions is difficult to guarantee, and iii) the workloads across all blockchain shards are severely unbalanced. In this talk, I am going to first introduce the preliminaries of blockchain scalability, then present my recent studies on exploring the scalability towards the sharding-based blockchains.
