Bitstring Status List is a working document from the W3C to support a privacy-preserving, space-efficient, and high-performance mechanism for publishing status information such as suspension or revocation of JSON and JSON-LD Verifiable Credentials.
Using DID-Linked Resources, we have been able to natively support Bitstring Status List on cheqd directly.
Bitstring Status List utilises to represent whether a Verifiable Credential has been suspended/revoked or not. A bitstring can be thought of as a long list of 1s and 0s, where, if the binary value of the position in the list is 1 (one), the is revoked, if it is 0 (zero) it is not revoked.

The issuer keeps a bitstring list of all Verifiable Credentials it has issued. The Status List is usually published by the issuer in the format of its own Verifiable Credential. This Verifiable Credential is generally hosted publicly on a centralised server or domain to enable third-party read-access.
Below are a list of alternatives for creating cheqd Status Lists.
Each issued Credential correlates with a position and index on the bitstring, so that a verifier will be able to correlate the value within the Credential against the public bitstring to ascertain whether the Credential has been revoked or not, using a as well as a .
cheqd stores each Status List and subsequent entries on-ledger as versions. This has notable benefits, including the provenance, legitimacy and security of the Status List. For a full list of benefits, see .
