PeerBFT: Making Hyperledger Fabric's Ordering Service Withstand Byzantine Faults

Jeonghyeon Ma, Yongrae Jo, Chanik Park
2020 IEEE Access  
Hyperledger Fabric, a permissioned blockchain platform assumes the correct behavior of the ordering service. It also adopts an endorsement policy to deal with malicious behaviors of peers.  ...  The experimental evaluation shows that PeerBFT achieves approximately 90.8% of TPS (Transactions Per Second) of Hyperledger Fabric with Solo ordering service.  ...  However, there is no consideration of malicious behavior of the ordering service of Hyperledger Fabric.  ...
