Kronos: A Robust Sharding Blockchain Consensus with Optimal Communication Overhead

arXiv:2403.03655v1 Announce Type: new
Abstract: Sharding enhances blockchain scalability by dividing the network into shards, each managing specific unspent transaction outputs or accounts. Cross-shard transactions pose a critical challenge to the security and efficiency of sharding blockchains. Current solutions, however, either prioritize security with assumptions and substantial investments, or focus on reducing overhead and overlooking security considerations.
In this paper, we present Kronos, a generic and efficient sharding blockchain consensus ensuring robust security. We introduce a buffer mechanism for atomic …
