Hyperledger Fabric 2.0 Arrives to Boost Enterprise Blockchain Adoption

Open-Source Platform for Blockchain Adoption, Hyperledger Announced the General Availability of Hyperledger Fabric 2.0

Hyperledger, an open-source collaborative effort created to advance cross-industry blockchain technologies, 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.

At the time of this announcement, said Brian Behlendorf, Executive Director at Hyperledger said,

“Hyperledger Fabric has established itself as a popular and practical distributed ledger framework and has powered much of the transition from conceptualization to commercialization we’ve seen in enterprise blockchain.”

Brian added, “Fabric 2.0 is a new generation framework developed by and for the enterprises that are building distributed ledger capabilities into the core of their businesses. This new release reflects both the development and deployment experience of the Fabric community and confirms the arrival of the production era for enterprise blockchain.”

Key Hyperledger Fabric 2.0 Features

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 an 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

New chaincode application patterns for collaboration and consensus

The same decentralized methods of coming to agreement that underpin the new chaincode lifecycle management can also be used in your own chaincode applications to ensure organizations consent to data transactions before they are committed to the ledger. Organizations can add automated checks to chaincode functions to validate additional information before endorsing a transaction proposal.

Additionally, human decisions can be modeled into a chaincode process that spans multiple transactions. The chaincode may require actors from various organizations to indicate their terms and conditions of agreement in a ledger transaction. Then, a final chaincode proposal can verify that the conditions from all the individual transactors are met, and “settle” the business transaction with finality across all channel members.

External chaincode launcher

The external chaincode launcher feature empowers operators to build and launch chaincode with the technology of their choice. The use of external builders and launchers is not required as the default behavior builds and runs chaincode in the same manner as prior releases using the Docker API.

Private data enhancements

Hyperledger Fabric 2.0 enables new patterns for working with and sharing private data, without the requirement of creating private data collections for all combinations of channel members that may want to transact. Specifically, instead of sharing private data within a collection of multiple members, you may want to share private data across collections at a transaction or state key level with selected channel members. Each private data collection may contain a single organization, or perhaps a single organization along with a regulator or auditor.

State database cache for improved performance on CouchDB

When using external CouchDB state database, read delays during endorsement and validation phases have historically been a performance bottleneck. With Hyperledger Fabric 2.0, a new peer cache replaces many of these expensive lookups with fast local cache reads.

Alpine-based docker images

Starting with 2.0, Hyperledger Fabric Docker images will use Alpine Linux, a security-oriented, lightweight Linux distribution. This means that Docker images are now much smaller, providing faster download and startup times, as well as taking up less disk space on host systems. Alpine Linux is designed from the ground up with security in mind, and the minimalist nature of the Alpine distribution greatly reduces the risk of security vulnerabilities.

Hyperledger Fabric is already widely deployed in PoCs and production networks of all sizes and scales. To ensure smooth transition to this new version, there is a range of documentation specifically for Upgrading to the latest release.
