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](https://trinsic.id/trinsic-basics-the-verifiable-credentials-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](https://www.w3.org/TR/vc-data-model/) 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](https://twitter.com/fennykyun/status/1564249472053514240) fennykyun > tldr\ > :: DID is just an URI\ > :: VC is a cryptographically verifiable credential using DID\ > :: SSI is a self-sovereign and privacy-preserving identity > :: Non-human (Machines, Bots, Goods, anything) also able to have DID, VC, and SSIs * [Understanding Verifiable Credentials](https://www.credivera.com/blog/understanding-verifiable-credentials) Credivera > The value of verifiable credentials and the critical role they will play to our future digital identities is undeniable.
