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.

>Our zero-knowledge proofs are part of the [Idemix protocol](http://domino.research.ibm.com/library/cyberdig.nsf/papers/EEB54FF3B91C1D648525759B004FBBB1/%24File/rz3730_revised.pdf), where they are used to prove the possession of [Camenisch-Lysyanskaya credentials](https://eprint.iacr.org/2001/019.pdf). We also use zero-knowledge proofs in the revocation protocol, which is based on [cryptographic accumulators](https://eprint.iacr.org/2008/539.pdf). —*[What Zero Knowledge Poof Algorithm is used in Sovrin?](https://forum.sovrin.org/t/what-zero-knowledge-proof-algorithm-is-used-in-sovrin/71/2)*
>Identity Mixer is not directly (re)implemented by Sovrin, but its cryptographic foundations are very similar, and Sovrin’s implementation includes most of its extended features (predicates, multi-credential, revocation, advanced issuance…). One of the researchers who helped to create Identity Mixer is on Sovrin’s Technical Governance Board and has offered insight to keep the implementations aligned on goals and methods.
