- Hyperledger Indy - Distributed Ledger and Utility Library - Twitter - Chat - Forum - Wiki - Documentation
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.
- hyperledger/indy-node
This codebase embodies all the functionality to run nodes (validators and/or observers) that provide a self-sovereign identity ecosystem on top of a distributed ledger. It is the core project for Indy; over time, all other indy-* projects may collapse into this one, except for indy-sdk.
- hyperledger/indy-sdk
This is the official SDK for Hyperledger Indy, which provides a distributed-ledger-based foundation for self-sovereign identity. Indy provides a software ecosystem for private, secure, and powerful identity, and the Indy SDK enables clients for it. The major artifact of the SDK is a C-callable library; there are also convenience wrappers for various programming languages and Indy CLI tool.
About
- Strengthening Hyperledger Indy and Self-Sovereign Identity 2019-07-08
Forrester’s recent “Top Recommendations for Your Security Program, 2019,” testifies to this, describing SSI as a “win” for customers and businesses, and urged chief information security officers (CISO) to “Empower your customers to control their own identities via self-sovereign identity.”
They can do this because exchanging verifiable digital credentials is at the heart of SSI. This ends the need for massive data silos, honeypots, and unsecured data repositories housed at countless corporations and organizations. Instead, anyone can hold secure and verifiable information about themselves
- An overview of Self-Sovereign Identity: the use case at the core of Hyperledger Indy 2019-05-01
Credential issuers, holders, and verifiers are peers on an SSI network. Any person or organization can play any or all of the roles, creating a decentralized system for the exchange of trustworthy, digital credentials.
- Credential issuers determine what credentials to issue, what the credential means, and how they’ll validate the information they put in the credential.
- Credential holders determine what credentials they need and which they’ll employ in workflows to prove things about themselves.
- Credential verifiers determine what credentials to accept, and which issuers to trust.

- Implementing Privacy by Design in Hyperledger Indy 2018-09 Infoq
Hyperledger Indy has been built using a privacy first approach. As the world shifts to more regulation, including GDPR and ePrivacy requirements, Indy can minimize the amount of details a user shares when having their data validated by a third-party system.
- Privacy by Design in Hyperledger Indy 2018-09-12 Hyperledger Foundation
Hyperledger Indy’s approach to privacy includes elliptic curve cryptography, pairwise DIDs, semi-trusted agents, agent-to-agent communication using techniques such as libsodium’s sealed box and authenticated encryption, zero-knowledge proofs, a separation between credentials and proofs, privacy-preserving credential revocation features, an affinity for data and key storage at the edge, and a carefully constructed wallet interface that manages personal secrets with industry best practices. In addition, privacy-preserving agent (device) revocation has been demonstrated as a proof of concept.

- The Rise of Self-Sovereign Identity - Hyperledger Indy 2018-07-03 WSO2
You can store your identities in a location where you can edit or delete them. After giving the location of your identities, the Indy platform lists your location with a globally identifiable name. When someone wants to read your identity data, the Indy platform points out the location of your identities. Let’s look into the details of how it works.
- Hyperledger Welcomes Project Indy 2017-05-02 {ANN)
Indy is all about giving identity owners independent control of their personal data and relationships. Indy is built so that the owner of the identity is structurally part of transactions made about that identity. Pairwise identifiers not only prevent correlation, but they stop third parties from transacting without the identity owner taking part since the identity owner is the only place pairwise identifiers can be correlated.
Development
- Hyperledger completes development of DID:Indy Method and advances toward a network of networks 2022-05-02 Linux Foundation, Howland & Bluhm
With the groundwork complete, networks and agent frameworks now need to incorporate the Indy:DID Method. This community adoption will increase the viability of the Indy and Aries project stack and position it to be the globally dominant way to issue and share verifiable credentials in a multi-ledger world.

The current maintainers stop active contribution to the further development of the Hyperledger Labs project Business Partner Agent, as well as the related project Business Partner Agent Helm Chart. To give existing users of the Business Partner Agent enough lead time, we are willing to continue maintaining the project for now. For more information see the Hyperledger Discord channel.

- A Framework for Designing Cryptographic Key Management Systems 2023-06-12
This Framework for Designing Cryptographic Key Management Systems (CKMS1) is a description of the topics to be considered and the documentation requirements (henceforth referred to as requirements) to be addressed when designing a CKMS. The CKMS designer satisfies the requirements by selecting the policies, procedures, components (hardware, software, and firmware), and devices (groups of components) to be incorporated into the CKMS, and then specifying how these items are employed to meet the requirements of this Framework

- Technical Design and Development of a Self-Sovereign Identity Management Platform for Patient-Centric Healthcare Using Blockchain Technology 2022-04-22 Blockchain Healthcare Today
To manage patient’s self-sovereign identity, we leveraged the Hyperledger Indy blockchain framework to store patient’s decentralized identifiers (DIDs) and the schemas or format for each credential type. In contrast, the credentials containing patient data are stored “off-ledger” in each person’s wallet and accessible via a computer or smartphone. We used Hyperledger Aries as a middleware layer (API) to connect Hyperledger Indy with the front-end, which was developed using a JavaScript framework, ReactJS (Web Application) and React Native (iOS Application).

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.
