Several representative solutions have been p roposed to improve the blockchain scalability. Especially\, sharding techn ique is believed as a promising Layer1 solution. Although blockchain shard ing can improve the throughput of blockchain systems significantly in theo ry\, there are some typical challenges behind this technique. For example\ , i) the number of cross-shard transactions in a sharding system is overwh elming\, ii) the atomicity of cross-shard transactions is difficult to gua rantee\, 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 t he scalability towards the sharding-based blockchains.\n\nSpeaker(s): Dr. Huawei Huang\, \n\nRoom: 3022 \, Bldg: 180\, Unitec Mt Albert Campus\, Auc kalnd\, North Island\, New Zealand\, Virtual: https://events.vtools.ieee.o rg/m/348359 LOCATION:Room: 3022 \, Bldg: 180\, Unitec Mt Albert Campus\, Auckalnd\, Nor th Island\, New Zealand\, Virtual: https://events.vtools.ieee.org/m/348359 ORGANIZER:billliu23112022@gmail.com SEQUENCE:3 SUMMARY:Exploring Blockchain Scalability using Sharding Techniques URL;VALUE=URI:https://events.vtools.ieee.org/m/348359 X-ALT-DESC:Description: <br /><p>Scalability has become a significant resea rch topic of blockchains\, since it is deemed as a bottleneck preventing b lockchain technologies from being largely adopted.
