Issue Verifiable Credential with Encrypted Status List 2021 Resource

There is a specific transaction type for issuing Verifiable Credentials that reference encrypted Status List Resources.

Step 1: Create an encrypted Status List on-ledger

Follow the tutorial here to create an encrypted Status List 2021 Resource on cheqd.

Step 2: Choose index number for Credential

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.

Step 2: Construct Credential Payload with Status List

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:
Example Request Format: Random Bitstring index

},
"type": [
"VerifiableCredential"
],
"@context": [
"https://www.w3.org/2018/credentials/v1",
"https://veramo.io/contexts/profile/v1"
]
}
},
"statusOptions": {
"statusPurpose": "revocation",
"statusListName": "status-list-2021-encrypted"
}
}
​
Example Request Format: Specified Bitstring index
{
"issuanceOptions": {
"credential": {
"credentialSubject": {

],
"@context": [

"https://veramo.io/contexts/profile/v1"
]
}
},
"statusOptions": {
"statusPurpose": "revocation",
"statusListName": "status-list-2021-encrypted",
"statusListIndex": 1456
}
}
​
Example Request Format: Bitstring index within a given range
{
"issuanceOptions": {
"credential": {
"credentialSubject": {
"name": "tweeddalex",
"id": "did:key:z6MkvG4dpKVpYwYqnwcjRdw8VZ3km4Sisgxm1igaPCFzskxe"
},
"issuer": {

]
}
},
"statusOptions": {
"statusPurpose": "revocation",
"statusListName": "status-list-2021-encrypted",
"statusListRangeStart": 2000,
"statusListRangeEnd": 3000
}
}
​
Example Request Format: Bitstring including omitted bits
{
"issuanceOptions": {
"credential": {
"credentialSubject": {
"name": "tweeddalex",
"id": "did:key:z6MkvG4dpKVpYwYqnwcjRdw8VZ3km4Sisgxm1igaPCFzskxe"
},
"issuer": {
"id": "did:cheqd:testnet:322761ea-587d-454a-a955-745200301b99"
},
"type": [
"VerifiableCredential"
],
"@context": [

]
}
},
"statusOptions": {
"statusPurpose": "revocation",
"statusListName": "status-list-2021-encrypted",
"statusListRangeStart": 10,
"statusListRangeEnd": 3000,
"indexNotIn": 13, 1807, 2434
}
}
​
Ensure that the "statusPurpose" and "statusListName" is the same as the existing Status List on-ledger, created in Step 1.

Step 3: Execute the transaction

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

Response format

If the transaction is successful, you will get returned a formatted Verifiable Credential, including a populated "credentialStatus" section.
