Design and Building a Data Loader and Viewer Engine for Blockchain-enabled Big Data Systems using Hyperledger Fabric

PoC covering the problem of transaction time manipulation (CVE-2024-45244) in the Hyperledger Fabric blockchain.

GrainBee is a robust blockchain-based solution designed to manage and track the distribution of rations efficiently and transparently. Built on Hyperledger Fabric, and CC-Tools this project ensures secure and reliable ration management through a modular architecture that includes a backend implemented in Go.

An attribute-based access controlled chaincode backend for a voting application.

Libraries with general helper functions that are often needed and used in the development of Hyperledger Fabric Chaincode in Go. By using these packages you can keep underlying Chaincode boilerplate code out of your contracts and focus on your business logic.
