Credential Status
A mechanism that lets a verifier check whether a credential has been revoked without contacting the original issuer's API.
Credential status, in the W3C Verifiable Credentials sense, is a pointer from inside the signed credential to an external resource that declares whether the credential is currently valid. The most common implementation is the W3C Bitstring Status List (previously StatusList2021): a compressed bit-array credential, itself signed, in which each credential's index encodes revoked/not-revoked.
Why this matters: revocation has to be discoverable by any verifier, not just the issuer's customers. If revocation only works via the issuer's private API, a third-party wallet or independent verifier can't detect revoked credentials — a security failure mode.
Bitstring Status List is on the LearnCoin roadmap but not yet shipped. Today, revocation is available via the LearnCoin /v1/credentials/verify endpoint and the public verification page — both reliable, but both require LearnCoin's infrastructure. The standards deep-dive and the transparency block on the /standards page flag this gap; the LearnCoin website does not claim Bitstring Status List conformance.
