Overview
A verifiable credential is a cryptographically signed claim about an individual that can be verified without contacting the issuer. It enables portable, tamper-proof attestations. It is a building block of decentralized identity.
How It Works
An issuer signs a credential describing a claim, such as a degree or membership. The holder presents it, and a verifier checks the signature and validity without needing the issuer online. The holder controls disclosure.
Why It Matters
Verifiable credentials enable trustless verification and reduce data silos. They support education, employment, and access use cases. They are central to Self-Sovereign Identity.
