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 interoperable with other blockchains or can be used standalone powering the decentralization of identity.
Evernym’s products are built on the open core of Hyperledger Indy. This community-governed codebase is available for anyone to study, use, and modify. The best place to start is with the getting started guide in the SDK Git repository.
The Indy community is very friendly, and developers can often get help from volunteers via chat or the mailing list. The documentation index for project Indy is a valuable developer resource as well.
Hyperledger Aries
Hyperledger Aries provides a shared, reusable, interoperable tool kit designed for initiatives and solutions focused on creating, transmitting and storing verifiable digital credentials. It is infrastructure for blockchain-rooted, peer-to-peer interactions. This project consumes the cryptographic support provided by Hyperledger Ursa, to provide secure secret management and decentralized key management functionality.
Hyperledger Ursa
Hyperledger Ursa is a shared cryptographic library, it enables implementations to avoid duplicating other cryptographic work and hopefully increase security in the process. The library is an opt-in repository (for Hyperledger and non Hyperledger projects) to place and use crypto. Hyperledger Ursa consists of sub-projects, which are cohesive implementations of cryptographic code or interfaces to cryptographic code.
