Welcome to Hyperledger Indy, a decentralized identity project of the Linux Foundation Decentralized Trust.

Hyperledger Indy provides tools, libraries, and reusable components for decentralized identity. It helps developers build privacy-preserving identity systems using decentralized identifiers, verifiable credentials, zero-knowledge proofs, and distributed ledger technology.

You can find more information on the Hyperledger Indy project page.

Hyperledger Indy is an open-source implementation of distributed ledger technology built specifically for decentralized identity.

Indy provides infrastructure for digital identities rooted in distributed ledgers, allowing identities to be interoperable across applications, organizations, administrative domains, and other silos.

Indy is designed to support privacy-preserving identity workflows where users can prove claims about themselves without revealing unnecessary personal information.

Hyperledger Indy is composed of several integrated parts:

• Ledger Infrastructure — A distributed ledger designed for decentralized identity metadata such as DIDs, schemas, credential definitions, and revocation registries.
• Node and Consensus Components — Software for running Indy ledger nodes and maintaining agreement across the network.
• Client and Resolver Libraries — Libraries for reading from and writing to Indy ledgers, resolving DIDs, and interacting with identity-related ledger data.
• DID and Credential Specifications — Specifications and supporting implementations for decentralized identifiers, verifiable credentials, and privacy-preserving credential exchange.

Together, these components let developers and organizations build decentralized identity networks and applications with ledger-backed trust, interoperability, and privacy-preserving credential workflows.

Hyperledger Indy allows developers and organizations to:

• Build decentralized identity networks
• Issue and verify verifiable credentials
• Use decentralized identifiers for identity interactions
• Support privacy-preserving credential presentations
• Use zero-knowledge proofs for selective disclosure
• Manage schemas, credential definitions, and revocation registries
• Build identity systems that work across organizations and applications
• Support self-sovereign identity and user-controlled data sharing

Example use cases include:

• Digital identity wallets
• Verifiable credential ecosystems
• Public identity utility ledgers
• Decentralized trust registries
• Education and workforce credentials
• Healthcare and government identity workflows
• KYC and compliance workflows
• Cross-organization identity interoperability

Hyperledger Indy welcomes developers, operators, researchers, identity architects, organizations, and privacy advocates interested in decentralized identity and verifiable credential infrastructure.

Good ways to get started:

1. Review the indy repository.
2. Explore the Indy documentation index.
3. Join community discussions on LFDT Discord. Channel: #indy
4. Attend community meetings. Indy community calls are open to everyone. These meetings are a good place to ask questions, discuss roadmap priorities, and learn how to contribute.

Past meeting recordings and presentations can be accessed through:

• LFX Individual Dashboard
• LFDT Meeting Calendar
• Hyperledger Indy YouTube playlist

For larger changes, please open an issue first so the community can discuss the design before implementation.

Hyperledger Indy is a graduated LFDT project. Indy continues to serve as a foundation for decentralized identity systems, verifiable credential networks, DID infrastructure, and privacy-preserving credential workflows.
