According to a recent press release, “Hyperledger, an open source collaborative effort created to advance cross-industry blockchain technologies, today announced the general availability of Hyperledger Fabric 2.0. This major release of Hyperledger Fabric, a distributed ledger framework that’s been under development by the Hyperledger community since 2016, delivers a number of features and enhancements needed to increase the efficiency and security of production deployments. Much of the work on Hyperledger Fabric 2.0 focused on new ways to manage the chaincode (or smart contract) lifecycle to maximize flexibility, remove bottlenecks and create more options to distribute governance. Security and data privacy were also big development priorities, so many features and enhancements are geared towards delivering more granular control of private channels and minimizing vulnerabilities.”
The release continues, “Key Hyperledger Fabric 2.0 features include: Decentralized governance for smart contracts — Hyperledger Fabric 2.0 introduces decentralized governance for chaincode, with a new process for installing a chaincode on your peers and starting it on a channel. The new Fabric chaincode lifecycle allows multiple organizations to come to agreement on the parameters of a chaincode, such as the chaincode endorsement policy, before it can be used to interact with the ledger. The new model offers several improvements over the previous lifecycle, including requiring multiple organizations to agree to the parameters of a chaincode, creating a more deliberate chaincode upgrade process and simplifying endorsement policy and private data collection updates.”
