> This codebase embodies all the functionality to run nodes (validators and/or observers) that provide a self-sovereign identity ecosystem on top of a distributed ledger. It is the core project for Indy; over time, all other indy-* projects may collapse into this one, except for indy-sdk.
* [hyperledger/indy-sdk](https://github.com/hyperledger/indy-sdk)
> This is the official SDK for Hyperledger Indy, which provides a distributed-ledger-based foundation for self-sovereign identity. Indy provides a software ecosystem for private, secure, and powerful identity, and the Indy SDK enables clients for it. The major artifact of the SDK is a C-callable library; there are also convenience wrappers for various programming languages and Indy CLI tool.

> Credential issuers, holders, and verifiers are peers on an SSI network. Any person or organization can play any or all of the roles, creating a decentralized system for the exchange of trustworthy, digital credentials.
>
> - Credential issuers determine what credentials to issue, what the credential means, and how theyll validate the information they put in the credential.
> - Credential holders determine what credentials they need and which theyll employ in workflows to prove things about themselves.
> - Credential verifiers determine what credentials to accept, and which issuers to trust.

> They can do this because exchanging verifiable digital credentials is at the heart of SSI. This ends the need for massive data silos, honeypots, and unsecured data repositories housed at countless corporations and organizations. Instead, anyone can hold secure and verifiable information about themselves
