Cross hyperledger fabric transactions

Proceedings of the 3rd Workshop on Cryptocurrencies and Blockchains for Distributed Systems, 2020
Hyperledger Fabric is a private block-chain based business logic solution that can safely accomodate transactions between untrusted or partially trusted participants. Moreover its scalable and modular structure makes Hyperledger Fabric capable of complex logical functions to handle transactions between different organizations. Hyperledger Fabric offers

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

Dependency Reduction Techniques for Performance Improvement of Hyperledger Fabric Blockchain

Big Data and Cognitive Computing
We propose dependency reduction techniques for the performance enhancement of the Hyperledger Fabric blockchain. A dependency hazard may result from the parallelism in Hyperledger Fabric, which executes multiple transactions simultaneously in a single ...

Combining ID’s, Attributes, and Policies in Hyperledger Fabric

, 2023
This work aims to provide a more secure access control in Hyperledger Fabric blockchain by combining multiple ID’s, attributes, and policies with the components that regulate access control. The access control system currently used by Hyperledger Fabric is first completely analyzed.

An in-depth investigation of the performance characteristics of Hyperledger Fabric

Computers & Industrial Engineering, 2022
Private permissioned blockchains are deployed in ever greater numbers to facilitate cross-organizational processes in various industries, particularly in supply chain management. One popular example of this trend is Hyperledger Fabric. Compared to public permissionless blockchains, it promises improved performance and provides certain features that ...

Detection of Phantom Reads in Hyperledger Fabric

IEEE Access
In concurrent transactional systems, a phantom read occurs when a transaction retrieves a set of data, and simultaneously, new data is inserted, updated, or removed from that set by one or more other transactions, leading to unexpected data being read ...
