A $p/2$ Adversary Power Resistant Blockchain Sharding Approach. (arXiv:2004.04798v7 [cs.DC] UPDATED)
cs.CR updates on arXiv.org arxiv.org
Blockchain Sharding is a blockchain performance enhancement approach. By
splitting a blockchain into several parallel-run committees (shards), it helps
increase transaction throughput, reduce computational resources required, and
increase reward expectation for participants. Recently, several flexible
sharding methods that can tolerate up to $n/2$ Byzantine nodes ($n/2$ security
level) have been proposed. However, these methods suffer from three main
drawbacks. First, in a non-sharding blockchain, nodes can have different weight
(power or stake) to create a consensus, and as such an …
