prepareExtrinsicToRevoke(statementUri, authorizationUri): Promise<SubmittableExtrinsic>

Dispatches a statement revocation transaction to the CORD blockchain.

Parameters

• statementUri: `stmt:cord:${string}`

The URI of the statement to be revoked.

Remarks

This function is responsible for revoking an existing statement on the blockchain. It constructs and submits a transaction to revoke the statement identified by the given URI. The transaction is authorized by the creator and signed by the provided author account.

Throws

• Thrown when there is an error during the dispatch process, such as issues with constructing the transaction, signing, or submission to the blockchain.

Example

const statementUri = 'stmt:cord:example_uri';
const creatorUri = 'did:cord:creator_uri';
const authorAccount = // ... initialization ...
const authorizationUri = 'auth:cord:example_uri';
const signCallback = // ... implementation ...

dispatchRevokeToChain(statementUri, creatorUri, authorAccount, authorizationUri, signCallback)
  .then(() => {
    console.log('Statement successfully revoked.');
  })
  .catch(error => {
    console.error('Error dispatching statement revocation to chain:', error);
  });
