    Walt.id is a library developped to handle decentralized identity within european reglations: https://github.com/walt-id/waltid-ssikit

    This could be a starting point for this debate

    Walt.id is a library developped to handle decentralized identity within european reglations: https://github.com/walt-id/waltid-ssikit

    This could be a strating point for this debate

    A page to introduce SSI (Self-sovereign identity) and decentralized identity : SSI Essentials: Everything you need to know about Decentralized Identity

    identity architectures history

    An explanation about DIDs (Decentralized Identity) and VCs (Verifiable Credentials) : What are Decentralized Identifiers (DIDs) & Verifiable Credentials (VCs)?

    The structure of a DID is:

    • DID Scheme: All DIDs begin with “did:”
    • DID method: This field specifies how to deal with this DID. When reading this part of the DID, computers understand where to go fetch the DID. It could be on a blockchain (EBSI) or on a DNS (web)
    • DID Method-specific identifier: Refers to the DID’s unique identifier within the method


    An user can request to associate one or several Verifiable Credentials to a DID. An Issuer will issue VC for this specific DID

    dids flow

    There are 3 components in a VC:

    1. Credential Metadata: Properties or attributes of the credential
    2. Claims: A statements about a subject (individual, legal entity, or thing).
    3. Proofs: cryptographic signatures tied to private keys that prove the user sharing the VC is the subject of the information

There are 3 components in a VC:

  2. Claims: A statements about a subject (individual, legal entity, or thing).
  3. Proofs: cryptographic signatures tied to private keys that prove the user sharing the VC is the subject of the information
