Wider: Scale Out Blockchain With Sharding by Account. (arXiv:2207.01978v1 [cs.DC])

The development of blockchain applications increased the demand for
blockchain performance. Among the attempts of many blockchain scale-out
solutions, sharding can improve performance and reduce the storage requirements
of each node. Sharding enhances the throughput of the entire blockchain. Most
sharding solutions have a fixed number of shards. We propose Wider chain with
sharding by account. The number of shards is increased to unlimited. Meanwhile,
Wider combines the idea of rollup and retains the main chain to confirm the
status …
