This page contains a growing collection of resources related to Evernym, the Sovrin Foundation, and Hyperledger Indy. It was born from [/awesome-decentralized-id](../README.md) and relates some of the same material. However, this list is focused on everything directly related to Hyperedger Indy.
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 DPKI. Among the United Nations 'Sustainable Development Goals' is for all the world to have access to a digital identity by 2030. Around 2016, the SDGs, blockchain, and the GDPR converged bringing much energy to the decentralized identity ecosystem.

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](https://sovrin.org/library/sovrin-governance-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.

>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.
