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, with an extractable EVM implementation. It can also be run on test networks such as Sepolia and Görli. Hyperledger Besu includes several consensus algorithms including Proof of Stake, Proof of Work, and Proof of Authority (IBFT 2.0, QBFT, 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
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.
Task Forces are short-term groups created by the Technical Oversight Committee to focus on specific deliverables. All Task Forces are open to anyone who is interested in getting involved, so feel free to check out the following groups and join the discussions on Discord and in Task Force calls. Learn more about Task Forces.

Hyperledger AnonCreds – short for “Anonymous Credentials”- is the most commonly used Verifiable Credential (VC) format in the world. Ledger agnostic and with a formal open specification, AnonCreds is a VC format that adds important privacy-protecting ZKP (zero-knowledge proof) capabilities to the core VC assurances.
|BEV is an accelerator/tool that helps developers rapidly set up and deploy secure, scalable and production-ready DLT network(s) that also allows new organizations to be easily on-boarded on the network. Bevel accelerates DLT network deployment and lets developers focus on building blockchain applications without having to waste precious time standing up the environment or worrying whether the network will scale and meet production requirements. Bevel facilitates a safe and secure way of deploying and operating different DLT platforms.|
|Hyperledger Cacti is a blockchain integration tool designed to allow users to securely integrate different blockchains.|
|Hyperledger Caliper is a blockchain benchmark tool, it allows users to measure the performance of a blockchain implementation with a set of predefined use cases. Hyperledger Caliper will produce reports containing a number of performance indicators to serve as a reference when using the following blockchain solutions: Hyperledger Besu, Hyperledger Burrow, Ethereum, Hyperledger Fabric, FISCO BCOS, Hyperledger Iroha, and Hyperledger Sawtooth.|
|Hyperledger Cello aims to serve as the operational dashboard for Blockchain, which reduces the effort required for creating, managing and using blockchains. Besides, it can also be used to facilitate creating Blockchain as a Service. Cello provides an operational console for managing blockchain’s efficiently and running on top of various infrastructures, e.g., baremetal, virtual machine, and various container platforms.|
|Hyperledger Firefly is a multiparty system for enterprise data flows, powered by blockchain. It solves all of the layers of complexity that sit between the low level blockchain and high level business processes and user interfaces. FireFly enables developers to build blockchain apps for enterprise radically faster by allowing them to focus on business logic instead of infrastructure.|
|Hyperledger Solang is a Solidity compiler written in rust which uses llvm as the compiler backend. Solang can compile Solidity for Solana and Substrate.|
|Hyperledger Transact aims to reduce the development effort in writing distributed ledger software by providing a standard interface for executing smart contracts that is separate from the distributed ledger implementation. Hyperledger Transact takes an extensible approach to implementing new smart contract languages called “smart contract engines,” that implement a virtual machine or interpreter that processes smart contract|
Note: Hyperledger Avalon, Hyperledger Burrow, Hyperledger Composer, Hyperledger Explorer, Hyperledger Grid, Hyperledger Quilt and Hyperledger Ursa have been moved to End of Life but the status and Hyperledger Transact has been moved to Dormant status. 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.
