Issue Credential with Encrypted Status List
Issue Verifiable Credential with Encrypted Status List 2021 and index
There is a specific transaction type for issuing Verifiable Credentials that reference encrypted Status List Resources.
Follow the tutorial here to create an encrypted Status List 2021 Resource on cheqd.
Each encrypted Status List is a bitstring, where each bit represents a Credential which is either revoked or unrevoked (or suspended or unsuspended).
Users should maintain and manage a list of which Credentials match with which specific bitstring indices to be able to revoke or suspend Credentials in the future, and to avoid collisions.
When issuing a Credential, you have the choice of whether to manually specify an index for the Credential within the bitstring, or randomly generate an index number anywhere in the bitstring, or within a given range.
As mentioned above, when constructing the payload for your Credential, including the encrypted Resource, you have a choice of how you would like to specify the index.
The following parameters may be included:
Parameter | Value | Optional |
|---|---|---|
"statusPurpose" | "revocation" or "suspension" | No |
"statusListName" | string | No |
"statusListVersion" | string | Yes |
"statusListRangeStart" | number | Yes |
"statusListRangeEnd" | number | Yes |
"statusListVersion" | number, or set of numbers | Yes |
Below are a set of examples of how these parameters may be included in Credential payload files for different purposes:

Ensure that the
"statusPurpose" and "statusListName" is the same as the existing Status List on-ledger, created in Step 1. Once you have constructed your payload file, and have saved it as a JSON file, use the transaction below to issue the Verifiable Credential.
veramo execute -m cheqdIssueRevocableCredentialWithStatusList2021 --argsFile path/to/payload.json
If the transaction is successful, you will get returned a formatted Verifiable Credential, including a populated
"credentialStatus" section. Result : {
