"Fabric Chaincode概述——开发支持、运行原理、版本区别"

The fourth session of the IBM Open Source Technology Micro Lecture Hall focused on the practical implementation of Chaincode in the context of Fabric and Hyperledger. The lecture, conducted by expert Li Chao, covered the essential aspects of Fabric Chaincode, including an overview of what Chaincode is, its development support, and operational principles. The session began with an introduction to Fabric Chaincode, explaining its purpose, the languages and SDKs that can be used for development, and its fundamental role in interacting with the Fabric blockchain. The presentation of Fabric 0.6 Chaincode followed, delving into the related concepts, the process of writing and debugging, and providing a deeper insight into the mechanics of Fabric 0.6 Chaincode. Moving on to Fabric 1.0 Chaincode, the lecture elucidated the associated concepts, the development and debugging processes, and emphasized on the unique channel through which Chaincode interacts with the Fabric blockchain. The practical implementation of an interface code, deployment on Fabric blockchain nodes, and the generation of unique transaction sources from the ledger, blocks, and transactions were also discussed. In summary, the session covered the essential aspects of Chaincode in the context of Fabric and Hyperledger, providing a comprehensive understanding of the development, deployment, and interaction processes. Participants gained insights into the languages, SDKs, and operational principles involved in the implementation of Chaincode. The lecture not only provided theoretical knowledge but also practical implementation and debugging guidance, enhancing the participants' capabilities in blockchain development and deployment.
