Welcome to the LF Decentralized Trust wiki. There is information here about all of the activities that are happening in the community and you are welcome to get involved with anything that looks interesting. We just ask that you follow our Code of Conduct when participating in a call, in a discussion online or in an in-person community event.
If you have any questions about the wiki or the community, send us an email at community-architects@lfdecentralizedtrust.org.
Note: If you're looking for historical information about the Hyperledger community, you are welcome to check out the Hyperledger wiki.
These 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 allows trusted online peer-to-peer interactions based on decentralized identities and verifiable credentials. Aries includes a protocol definition, tools, and reference implementations. The Aries protocol supports identities rooted in a variety of distributed ledgers or blockchains. This approach to identity is often called Self Soverign Identity (SSI).
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 Cacti is a blockchain integration tool designed to allow users to securely integrate different blockchains.
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 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 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.
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.
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.
Hyperledger Bevel 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 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.
Credebl is an open-source Decentralized Identity & Verifiable Credentials Management Platform that is used to build the Decentralized National Digital ID for Royal Government of Bhutan & Papua New Guinea, and Sovio.id Platform by AYANWORKS.
Hiero is the open source DLT codebase used to build the Hedera network; including the hashgraph consensus algorithm and all core services, tooling and libraries. Hiero supports the development of a wide range of decentralized applications and core platform features tailored for the Hedera network, including wallets, exchanges, explorers, bridges, SDKs, private ledgers, and advanced cryptographic solutions.
Hyperledger Identus Identus provides components to develop decentralized identity solutions that adhere to widely recognized self-sovereign identity (SSI) standards. It offers complete DID and verifiable credential functionality and simplifies the complexities of adopting a decentralized identity solution into existing and new workflows.
Lockness aims to establish a new open source ecosystem focused on key management and digital signature protocols, including technologies like Multi-Party Computation (MPC), Threshold Signature Schemes (TSS), Hardware Security Modules (HSM) and other state-of-the-art protocols in public key cryptography and cryptographic modules.
Hyperledger Solang is a Solidity compiler written in rust which uses llvm as the compiler backend. Solang can compile Solidity for Solana and Substrate.
Web3j is a highly modular, reactive, type safe Java and Android library for working with Smart Contracts and integrating with clients (nodes) on the Ethereum network.
Trust Over IP provides a robust, common standard and complete architecture for Internet-scale digital trust.
Note: Hyperledger Avalon, Hyperledger Burrow, Hyperledger Composer, Hyperledger Explorer, Hyperledger Grid, Hyperledger Quilt, Hyperledger Sawtooth, Hyperledger Transact and Hyperledger Ursa have been moved to Archived status. The code for the projects is still available.
LFDT 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 projects initially started out as a lab and then later become official community projects. Anyone is welcome to start a new lab and you're also welcome to contribute to an existing lab.
Note that there are also a number of labs that are in the Hyperledger Labs repositories and have not yet migrated to LFDT Labs.
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.
