Scalability has become a significant research topic of blockchain, 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.
Dr. Huawei Huang is currently an Associate Professor with the School of Software Engineering, Sun Yat-sen University, China. He earned his CSE Ph.D. degree from the University of Aizu (Japan) in Sep., 2016. His current research interests mainly focus on blockchain scalability. He has served as a research fellow of Japan Society for the Promotion of Science (JSPS), a visiting scholar at Hong Kong Polytechnic University, a program-specific Assistant Professor at Kyoto University, Japan. He has published research papers on IEEE/ACM conferences and journals, including INFOCOM, ICDCS, IWQoS, SRDS, IEEE JSAC, TPDS, TMC, TC, TCC, TGCN, and etc. He is a PI or co-PI of several blockchain-related research projects funded by NSFC and CCF. He has served as a leading guest editor for blockchain special issues at IEEE JSAC and IEEE OJ-CS, operation-committee chair for IEEE Symposium on Blockchain at IEEE SERVICES 2021, and TPC chair for blockchain workshops organized at GLOBECOM, ICC, and MetaCom2023.
