Revoking multiple documents
If you open the previously wrapped documents side by side, you will notice:
- they have a different
targetHash: it uniquely identifies any document
- they have the same
merkleRoot: it uniquely identifies any group of wrapped documents.
When you revoke a document you can use any of those hash, but the result will be different depending on the one used:
- when using the
targetHash, only the document will be revoked.
- when using the
merkleRoot, all the documents wrapped together (in the same batch) will be revoked.
If you run again the command above, by using the
merkleRoot of the documents, then will all be revoked.
