MS-PBFT: A Master-Slave Multichain Consensus Mechanism Based on Pre-Broadcast and Threshold Signatures
Kang, Bohan, Chen, Yunzhi, Zhu, Jianming · Tehnicki vjesnik - Technical Gazette · 2024
This paper addresses scalability limitations in blockchain systems for supporting multi-asset transactions by proposing a master-slave multi-chain architecture.The underlying consensus protocol, called MS-PBFT, utilizes pre-broadcast and threshold signatures to reduce communication overhead.Experimental results demonstrate that MS-PBFT achieves substantially higher transaction throughput and lower latency compared to PBFT consensus, showcasing efficiency gains.This work provides a useful blockchain structure and consensus approach to enable classification of digital assets and concurrent processing across chains.
