JSON (JWT)

JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object.

This information can be verified and trusted because it is digitally signed.

JWTs are widely used in legacy identity infrastructure, underlying the frameworks used by OAuth 2.0 and OpenID Connect. As such, there is a plethora of software libraries and toolkits for developers to build upon using JWT, making their adoption far more seamless than other Verifiable Credential formats.
