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:
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.
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
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
