Create a Verifiable Credential Status List v2021 on-ledger

Credential Status Lists are on-ledger objects which can be used to mathematically derive whether an issued Credential has been revoked, suspended or is still valid.

Get started

Understanding Status List v2021

The Status List 2021 Specification utilises bitstrings 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 verifiable credential is revoked, if it is 0 (zero) it is not revoked.

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able to correlate the value within the Credential against the public bitstring to ascertain whether the Credential has been revoked or not, using a validate algorithm as well as a bitstring expansion algorithm.

Where is the StatusList usually published?

The issuer keeps a bitstring list of all Verifiable Credentials it has issued. The StatusList 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.

Where does cheqd store the Status List?

cheqd stores each Status List and subsequent entries on-ledger as DID-Linked Resource versions. This has notable benefits, including the provenance, legitimacy and security of the Status List. For a full list of benefits, see the context for creating DID-Linked Resources.


Below are a list of alternatives for creating cheqd Status Lists.
