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 or for information about community activity that hasn't been migrated to the LFDT wiki yet, you are welcome to check out the
Hyperledger wiki
Graduated Projects
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.
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.
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 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.
Incubation Projects
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.
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.
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.
Minokawa
is a domain-specific language purpose-built for zero-knowledge execution that is focused on making smart contract development accessible, secure and practical.
Paladin
is a platform for building programmable privacy preserving tokens on EVM, with integrated client and wallet. Support for several privacy frameworks including ZKP tokens, issuer-backed tokens, and private smart contracts.
Hyperledger Solang
is a Solidity compiler written in rust which uses llvm as the compiler backend. Solang can compile Solidity for Solana and Substrate.
Smoot
is a modular, vendor-agnostic interoperability framework designed to enable seamless communication and execution across diverse blockchain networks.
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.
Joint Development Foundation Projects
Trust Over IP
provides a robust, common standard and complete architecture for Internet-scale digital trust.
Archived Projects
Note:
Hyperledger Aries
Hyperledger Avalon
Hyperledger Burrow
Hyperledger Composer
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.
Labs
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. There are also some former projects that have been moved to labs:
Hyperledger Bevel
Hyperledger Caliper
Hyperledger Cello
Hyperledger Explorer
Task Forces
Task Forces are short-term groups created by the [Technical Advisory Council 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.
