--- date: 2018-12-13 layout: single title: "Hyperledger Indy Resources" description: "A growing collection of educational resources related to Hyperledger Indy, the Sovrin Foundation, and Evernym." excerpt: > 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. header: image: "https://decentralized-id.com/images/evernym-indy-sovrin.png" caption: "[OdysseyHackathon-21st Century Digital Citizenship Presentation](https://www.slideshare.net/OdysseyHackathon/21st-century-digital-citizenship-presentation)" permalink: /hyperledger/indy/ canonical_url: 'https://decentralized-id.com/hyperledger/indy/' redirect_from: - indy-sovrin/ - indy-sovrin - id-initiatives/indy-ecosystem - id-initiatives/indy-ecosystem/ - Indy-Sovrin/ - Indy-Sovrin - indy-ecosystem - hyperledger/indy sidebar: title: DIDecentralized nav: "sovnav" last_modified_at: 2019-07-10 tags: ["Evernym","Indy","Von"] categories: ["Sovrin Foundation","Hyperledger Foundation"] --- **Protocol, Governance, Education, Ecosystem** ![](https://i.imgur.com/6O3gTXX.png) This page contains a growing collection of educational resources related to Hyperledger Indy, the Sovrin Foundation, and Evernym.
