Hyperledger

These Hyperledger projects have successfully exited the incubation phase (see the Project Lifecycle document for more details about Graduated Projects).  All of these projects are open, so feel free to get involved with anything that looks interesting.  You can also add all Project calls to your calendar to find out about upcoming meetings.

	Hyperledger Aries provides a shared, reusable, interoperable tool kit designed for initiatives and solutions focused on creating, transmitting and storing verifiable digital credentials. It is infrastructure for blockchain-rooted, peer-to-peer interactions. This project consumes the cryptographic support provided by Hyperledger Ursa, to provide secure secret management and decentralized key management functionality.
	Hyperledger Besu is an Ethereum client designed to be enterprise-friendly for both public and private permissioned network use cases. It can also be ran on test networks such as Rinkeby, Ropsten, and Görli. Hyperledger Besu includes several consensus algorithms including PoW, and PoA (IBFT, IBFT 2.0, Etherhash, and Clique). Its comprehensive permissioning schemes are designed specifically for use in a consortium environment.
	Hyperledger Fabric is intended as a foundation for developing applications or solutions with a modular architecture. Hyperledger Fabric allows components, such as consensus and membership services, to be plug-and-play. Its modular and versatile design satisfies a broad range of industry use cases. It offers a unique approach to consensus that enables performance at scale while preserving privacy.
	Hyperledger Indy provides tools, libraries, and reusable components for providing digital identities rooted on blockchains or other distributed ledgers so that they are interoperable across administrative domains, applications, and any other silo. Indy is interoperable with other blockchains or can be used standalone powering the decentralization of identity.
	Hyperledger Iroha is designed to be simple and easy to incorporate into infrastructural or IoT projects requiring distributed ledger technology. Hyperledger Iroha features a simple construction, modular, domain-driven C++ design, emphasis on client application development and a new, crash fault tolerant consensus algorithm, called YAC.
	Hyperledger Sawtooth offers a flexible and modular architecture separates the core system from the application domain, so smart contracts can specify the business rules for applications without needing to know the underlying design of the core system. Hyperledger Sawtooth supports a variety of consensus algorithms, including Practical Byzantine Fault Tolerance (PBFT) and Proof of Elapsed Time (PoET).

Special Interest Groups (SIGs) are industry specific groups of community members working together to help drive adoption of Hyperledger.  All of these groups are open, so feel free to get involved with anything that looks interesting.  You can also add all Special Interest Group calls to your calendar to find out about upcoming meetings. Learn more about Special Interest Groups.

Hyperledger is a global community and people contribute from all over the world. In some places community members have organized regional activities for those who share a common geography and/or language. Check out the information below to see how to connect with an existing regional community or learn how to create a new regional chapter.

Working Groups are focused on building community around different challenges faced by the Hyperledger community.  All of these groups are open, so feel free to get involved with anything that looks interesting.  You can also add all Working Group calls to your calendar to find out about upcoming meetings.  Learn more about Working Groups.

These Hyperledger projects are in the incubation phase (see the Project Lifecycle document for more details about Incubation Projects).  All of these projects are open, so feel free to get involved with anything that looks interesting.  You can also add all Project calls to your calendar to find out about upcoming meetings.

Note: Hyperledger Avalon, Hyperledger Burrow, Hyperledger Composer, Hyperledger Explorer and Hyperledger Quilt have been moved to End of Life but the code for the projects is still available.

Hyperledger Labs provides a space (i.e., GitHub repos) where work can easily be started without the creation of a project.  Labs are a good place to experiment and to start to build a community around an idea.  Several Hyperledger projects initially started out as a lab.  Anyone is welcome to start a new lab and you're also welcome to get involved in any of the existing labs.  The following labs have also set up regular community calls where you can dial-in to learn more, ask questions and collaborate with others.
