On a more serious note: any notarization effort with the Ordinal protocol can only certify the existence of certain documents in a given moment and certify the possession of that document. It cannot assess the validity of such a document or the existence of any other version of it. (I am thinking of using the possession of a certain sat as a digital representation of the possession of something in the real world, such as a car or a house).
There is no reason to use Ordinals attack to do something like that. In Ordinals you will have to first create a new Taproot address created from the script containing the "document" then send some coins to that address (1st tx). Then you'll have to spend those coins so that you reveal the script and the document inside it on the blockchain in another transaction (2nd tx).
You could already do that using OP_RETURN as it has been done before. All it takes is one transaction with an OP_RETURN output containing the information related to the documents proving possession of the thing in real world.
If I am not wrong there are limits of data in each OP_RETURN with the need of splitting the data in multiple transactions.
Ordinals I think overcome this limitation in a more viable way.
Or you could just timestamp the hash of the document, but this implies you have to safely store the original document elsewhere (maybe on
YouTube?)
