>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.

  >Note that the main risk may not be that a Cloud Provider or some of its key staff goes rogue, but that a rogue nation gives a secret order to subtly sabotage the system to a Cloud Provider that has its headquarters in that nation. Sufficient jurisdictional diversity is hence needed for both Stewards and its supporting Cloud Providers, to assure that such a sabotage attempt does not go undetected.
