Selective Disclosure JWT. A token format that lets a holder reveal only chosen claims from a credential, used for privacy-preserving verifiable credentials and EU digital identity.

SD-JWT won the format argument for European digital identity because it is a JWT: existing libraries, existing tooling, and a mental model developers already have, with salted per-claim hashes providing selective disclosure. The trade-off against BBS is that a verifier can see how many claims were withheld, and presentations are linkable unless the wallet takes extra steps.
