A Faster Blockchain Sharding Protocol for Decentralized Ledger
Dongdong Liu, Ming‐Sheng Wang, Taotao Li, Ya Han · 2022
We propose FBSChain, a faster blockchain sharding protocol based on quorum-based BFT algorithm (running as sharding consensus) and use a vertical committee structure to assist in the decoupling of transaction confirmation and block generation. We utilize a set of clients to drive all these related processes. In addition, we deploy an improved common-coin scheme without any private setup to generate the randomness for reconfiguration. The protocol can perform better with less computational and communication costs and improve system scalability without compromising security performance.
