Description
The HLF-Connector is a project within the Hyperledger Labs community that provides a way to connect to and interact with Hyperledger Fabric Blockchain Networks from external applications using REST APIs & Kafka based Topics. This connector acts as a gateway between Fabric and non-Fabric applications, allowing external applications to securely read and write data to the Fabric blockchain through both synchronous and asynchronous modes of interaction. HLF-Connector provides a convenient and flexible way to integrate Fabric blockchain networks into external applications, allowing developers to build robust and secure decentralized applications that can interact with the Fabric network.
