Hyperledger Indy
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 in active development across the following areas:
Distributed Ledger
Client Tools
Note: We are in the process of moving our Client Tools work to Hyperledger Aries. We recommend engaging with both communities for the time being if you interested in building applications on top of an Indy network.
- The Indy SDK has been deprecated in favor of the Indy and Aries shared libraries. Please refer to the Deprecation Notice for information on the replacement libraries.
indy-agent (superseded by project aries)
Shared Components
Key Characteristics
Distributed ledger purpose-built for decentralized identity
Correlation-resistant by design
DIDs (Decentralized Identifiers) that are globally unique and resolvable (via a ledger) without requiring any centralized resolution authority
Pairwise Identifiers create secure, 1:1 relationships between any two entities
Verifiable Credentials in an interoperable format for exchange of digital identity attributes and relationships, currently in the standardization pipeline at the W3C
Zero Knowledge Proofs which prove that some or all of the data in a set of Claims is true without revealing any additional information, including the identity of the Prover
Documentation
An index of Indy documentation can be found here.
The documentation of the nitty gritty of the underpinnings of the code is located in the “docs” folder of each repo.
Note: Indy Documentation is in the process of migrating to: indy.readthedocs.io

Meetings
Identity WG Implementors Call
This is the call to discuss how to leverage Indy within your identity solution. More information is on the page Identity WG Implementors Call
Indy Contributors Call
People who want to contribute to Indy should join this call. This does not replace our asynchronous collaboration, but should help us keep everyone up-to-date and moving together.
Calls happen every other week: Europe afternoon / US morning: Monday at 8AM Los Angeles, 11AM New York, 4PM London, 18H Moscow
Location: https://zoom.us/j/244779296
Discussion items: upcoming releases, current PRs, work that will generate future PRs, architecture changes that will impact downstream teams, project standards, best practices, design, etc.
Agendas: Indy Contributors Meeting
You can work with us between calls on the #indy-contributors channel on Rocket Chat.
