Performance Evaluation of Hyperledger Fabric
2020 IEEE International Conference on Informatics, IoT, and Enabling Technologies (ICIoT), 2020 Blockchain is a distributed secure ledger that eliminates the need for centralized authority to store data. The centralized approach has several limitations as it is a Single-Point-of-Failure and a third-party might be needed. Blockchain, on the other hand, provides decentralized, secure and trustless framework that eliminates the need for a third ...

Hyperledger Fabric: Evaluating Endorsement Policy Strategies in Supply Chains [PDF]
2020 IEEE International Conference on Decentralized Applications and Infrastructures (DAPPS), 2020 Hyperledger Fabric is a permissioned blockchain solution, in which network participation is controlled by predefined rules. This makes it an attractive platform for enterprise settings. In Fabric, endorsement policies are used to specify the peers that must confirm a transaction before it can be considered as valid and appended to the ledger. This work
