Introduction
One of the main highlights of Hyperledger Fabric v2 is the concept of decentralized governance for smart contracts. It introduces peer chaincode lifecycle, which focuses on improving chaincode management between multiple organizations. Using the new lifecycle, installation, and upgrading of chaincodes requires approval from multiple organizations before the chaincode can be interacted with.
The latest fabric-sdk-node update also removed the fabric-client library, which was mainly responsible for handling administrative tasks such as chaincode and channel management on the network. These tasks now instead have to be carried out through the peer CLI.
