On Private Data Collection of Hyperledger Fabric

2021 IEEE 41st International Conference on Distributed Computing Systems (ICDCS), 2021
Hyperledger Fabric is a popular permissioned Blockchain framework for a consortium of organizations to develop Blockchain based applications and transact within the consortium. Hyperledger Fabric introduces a fine-grained access control mechanism called the private data collection (PDC), which allows private data to be shared by only a subset of ...

Transparent Logging with Hyperledger Fabric

2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC), 2019
Today a massive amount of data is used for machine learning (ML) and artificial intelligence (AI) to derive knowledge about the world and do automated decision making. All this data contains personal and/or sensitive data, and thus privacy is becoming more and more important.

Transactive Energy on Hyperledger Fabric

2019 Sixth International Conference on Internet of Things: Systems, Management and Security (IOTSMS), 2019
As home solar power generation continues to gain popularity, trading excess power within the community is the next logical step. Locally generated power can enrich communities, cut down on transmission losses and provide some measure of energy security. In order to facilitate intra-neighborhood energy transactions, we propose a model that leverages the

Performance Diagnosis and Optimization for Hyperledger Fabric

2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS), 2020
Hyperledger 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, 2019
Introduction. 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

2019
In 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 ...
