Awesome Sovrin and Hyperledger Indy Resources

Protocol, Governance, and Immediately Surrounding Ecosystem

This document was born from /awesome-decentralized-id and contains much of the same material.
However, this one is focused specifically on, and has additional material for Evernym, Sovrin, and Hyperledger Indy.

Since the information is all inter-related, there is some overlapp, and some jumping back and might still be required. Still, I think its good to have this page separate for information directly related to indy.

Sovrin Stewards^

The Sovrin ledger is operated by Stewards, trusted organizations within the ecosystem who have agreed to abide by the requirements in the Sovrin Trust Framework and are responsible for operation the nodes that maintain the Sovrin distributed ledger.

Stewards also, as a group, accept or reject any changes to the ledger-specific portions of the Sovrin open source code by virtue of that role. They thus provide a counterbalance to the Sovrin architects who maintain the Indy code base.

• Zero-Knowledge Proofs Starter Pack (Not ID related)
• Zero-Knowledge Proofs: Privacy-Preserving Digital Identity with Clare Nelson

Our zero-knowledge proofs are part of the Idemix protocol, where they are used to prove the possession of Camenisch-Lysyanskaya credentials. We also use zero-knowledge proofs in the revocation protocol, which is based on cryptographic accumulators. —What Zero Knowledge Poof Algorithm is used in Sovrin?

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. —How is IDEMix Implemented?

Evernym-Sovrin-Indy Adoption^

• Hyperledger Ursa "includes the Hyperledger Indy-Crypto code base that is the building block for anonymous credentials, the verifiable credentials protocol, in indy-sdk used by the Sovrin Network. [...] We are hopeful the shared library will help other platforms better incorporate and use ZKP-based credentials and leverage Sovrin for their identity component." (From Nathan George on Sovrin Telegram)[ϟ]
• Verified Organization Network [G] [>]
  • "an initiative by the government of British Columbia to create a trusted network of organizational data. It allows organizations to claim credentials that are part of their own digital identity, using a component called TheOrgBook[G] that lists entities with their associated public verifiable claims.

Further NPO cohorts are already planned for 2019.

Self Sovereign Identity^

Internet Identity Workshop is where the quest for concious, user-centric, identity began. Rebooting Web-of-Trust Workshops sprung from the IIW, focused on creating standards for decentralized identifiers, along with decentralized key managment\PKI. The United Nations 'Sustainable Development Goals' among which is for all the world to have access to a digital identity by 2020. The UN SDGs, blockchain, and the GDPR converged bringing much energy into the identity ecosystem. Additional history and background information may be found at awesome-decentralized-id.

Christopher Allen[T][G] details the overarching history of internet idenitity standards in his seminal work:
