Performance Diagnosis and Optimization for Hyperledger Fabric
2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS), 2020Hyperledger Fabric is a permissioned blockchain platform which can solve the trustless problems among enterprises. However, the limited transaction throughput prevents the further use of Fabric platform. The performance of Fabric network depends on many factors, such as network parameters, node numbers and hardware limitations.

Increasing concurrency in hyperledger fabric
Proceedings of the 12th ACM International Conference on Systems and Storage, 2019Introduction. The execute-order-validate blockchain architecture, introduced by Hyperledger Fabric (HLF) [1], allows parallel transactions execution and validation, thus raising the need for transaction isolation. Today transaction isolation is attained by locking the entire state database (DB) during simulation of transactions and state update.

Ripping the Fabric: Attacks and Mitigations on Hyperledger Fabric
2019In this paper, we take a closer look at the attack surface of permissioned blockchains by focusing on Hyperledger Fabric and present scenarios where the assumptions of trust could lead to possible attacks on an organization’s ledger. We systematically examine each participant and treating it as a malicious entity look at the attacks possible on the ...
