  • Introduction to Hyperledger Sovereign Identity Blockchain Solutions: Indy, Aries & Ursa 2020-09-03 (LFS172)
  • Hyperledger Aries is the Present and the Future of Internet-Scale Trusted Verifiable Credential Ecosystems 2022-09-13 Indicio

    While no technology runs perfectly on every device, a signal strength of Aries, AnonCreds, and Indy is that they work on the vast majority of current devices and systems, including $35 smart phones and low powered IOT/embedded devices. They represent the most inclusive way into this technology, which is an important factor in their popularity.

    The TSC commended the Aries project during the meeting for the project’s highly diverse contributors. Achieving a high number of organizations contributing to a project at Hyperledger is often a challenge. Congratulations are due to those participating in and supporting the Aries Project.

  • Hyperledger Aries to Enable Blockchain-Agnostic, Self-Sovereign Identity 2019-07-16 Ravikant Agrawal

    In two years since the introduction of Hyperledger Indy in 2017 […] To clarify and keep track of new and existing peer-to-peer interaction code for secrets management, verifiable information exchange, and secure messaging across different blockchains and other distributed ledger technologies, Hyperledger Aries was set in motion.

  • Hyperledger Aries: Open Source Interoperable Identity Solution – Nathan George – Webinar 30 2019-06-18 SSI Meetup

    Aries will be the industry’s first implementation of interoperable open source wallets for digital credentials that use the DKMS (Decentralized Key Management System) architecture that Evernym pioneered under a contract with the U.S. Department of Homeland Security.

  • Hyperledger Aries: The Next Major Step Towards Interoperable SSI 2019-05-30 Evernym

    Aries was born out of the work on identity agents and identity wallets that began in the Hyperledger Indy project. As a company focused entirely on decentralized identity, Evernym was one of the original founders of the Sovrin Network and contributed the first code to the open source project Hyperledger Indy.

    In addition to being able to support more ledger technologies than just Indy, Aries can work with multiple ledgers at the same time. This allows Agents to use each ledger according to the unique power offered by each, instead of requiring anchoring to only one ledger. In the future, Agents will be able to integrate not only with the recently announced Ion DID method, but also Ethereum, Hyperledger Sawtooth, Bitcoin, Hyperledger Fabric, and others.

  • Announcing Hyperledger Aries, infrastructure supporting interoperable identity solutions! 2019-05-14 Hyperledger Foundation

    Hyperledger Aries, the newest Hyperledger project (the13th!), is a shared infrastructure of tools that enables the exchange of blockchain-based data, supports peer-to-peer messaging in various scenarios, and facilitates interoperable interaction between different blockchains and other distributed ledger technologies (DLTs).

    There are three projects under the Hyperledger umbrella related to digital identity. Hyperledger Indy, Aries, and Ursa. […] describe their purpose and how they’re related to each other.

  • Learnings from Aries, Indy and Various Verifiable Credential Implementations 2022-08-13 Northern Block
    1. The various elements are evolving with the community to address specific use cases, and interdependencies between them are being eliminated to allow for ultimate flexibility and interoperability, where required.
    2. Convergence seems to be happening across various elements of the ecosystem. Standards such as OIDC and mDL are all now in dialogue with W3C, AnonCreds, Aries, etc. Mobile is a predominant technology, just like the way laptops were once upon a time. To reduce consumer friction and drive adoption, convergence of all these different technologies is required inside a mobile environment
  • Aries Agent Test Harness Enhancement Project 2022-07-27 IDLab

    To enable interoperability in the Aries VC ecosystem, a number of standards are defined in the form of Request for Comments (RFC). These RFCs are grouped into Aries Interop Profiles (AIP). These profiles, in turn, define which group of RFCs an agent has to conform to, in order to be labelled AIP compliant.

  • Indicio Wins British Columbia Code With Us Challenge to Upgrade Hyperledger Indy 2022-01-18 Indicio

    Most of Hyperledger Indy’s development occurred prior to the completion of the standard DID Specification by the W3C and, as a result, identifiers written to one network are currently not resolvable on other networks. A new did:indy DID Method will fix that and make it easier for decentralized identity products and services to interoperate across different Indy networks.

  • SITA uses blockchain, decentralized identity for pilot license verification 2021-11-16 Ledgerinsights

    Using the self-sovereign identity solution Hyperledger Aries, almost everything works peer to peer between the license issuer and the pilot and between the pilot and the verifier.

  • Indicio.Tech releases Aries Mediator Agent 2020-12-31

    The Indicio Mediator Agent is the company’s latest contribution to Aries Cloud Agent Python (ACA-Py) and the Aries Toolbox. Following RFC 0211: Mediator Coordination, Indicio built on the work of the open-source community to make mediation interoperable and vendor agnostic. This expands the opportunities for mobile wallet implementations. […] Indicio.tech is committed to becoming a resource-hub for decentralized identity, providing enterprise-grade open source tools to its clients and to the community. This includes the Private Networks build service, the Indicio TestNet, and a variety of customizable training programs.

    • A mobile app that Alice uses to manage credentials and to connect to others is an agent for Alice.
    • A cloud-based service that Alice uses to expose a stable endpoint where other agents can talk to her is an agent for Alice.
    • A server run by Faber College, allowing it to issue credentials to its students, is an agent for Faber.

    Having a tight definition of an agent may not matter in all cases. However, it is important when we are trying to understand interoperability goals. We want agents to be able to interact with one another. Does that mean they must interact with every piece of software that is even marginally agent-like? Probably not.
