DIDs

W3C Press Release - Decentralized Identifiers (DIDs) v1.0 becomes a W3C Recommendation worth reading to see who contributed comments (and notice who didn’t)

For individuals in particular, DIDs can put them back in control of their personal data and consent, and also enable more respectful bi-directional trust relationships where forgery is prevented, privacy is honored, and usability is enhanced.

DID Auth

  • SSI Interaction Patterns

    While the DID Authn pattern is simple, it is not as flexible as we need in some situations. For more complicated scenarios, we can use verifiable credentials. The first scenario we’ll consider is where the same organization is issuing and verifying the credential.

  • The Time for Self-Sovereign Identity is Now Kim Hamilton Duffy, Learning Machine (Now Hyland Credentials) Oldie but Goodie by Kim Hamilton Duffy from when she worked at Learning Machines

    Technically, Verifiable Claims are claims made about a “subject” (identified by a digital identifier such as a DID) that are rendered tamper proof through digital signatures. The authenticity of digital signatures may, in turn, be established through issuer identifiers, which may also be expressed as DIDs.

  • The Verifiable Credential’s Model

    At the core of every self-sovereign identity (SSI) use case is what we call the verifiable credentials model. This simple yet effective model helps conceptualize how verifiable credentials are exchanged between people and organizations.

  • According to W3: "Verifiable credentials represent statements made by an issuer in a tamper-evident and privacy-respecting manner."

  • DID, in short for Decentralized Identifier, is basically a unique string of random numbers and letters fennykyun
