Toward reducing cross-shard transaction overhead in sharded blockchains
Liuyang Ren, Paul A. S. Ward, Bernard Wong · 2022
Sharding is a promising approach to high-performance blockchains and has been extensively explored in academia recently. However, sharding also introduces cross-shard transactions, which require expensive inter-shard coordination to ensure state consistency. Such transactions significantly limit the performance of sharded blockchains.
