You overhear a conversation:

"Hey Udee, wouldn't it be funny if we used the big 4 megger txid as a private key!

"Haha, yeah and the txid starts with '03' as well"

"Ohh you know what would also be good Erik, is if we made an additional encumbrance where preimage of the raw transaction is needed!"

"Well, that might be a bit much, but we could use it as a pre-preimage, or in other words, use the hash of the transaction"

"Good idea Rine Dale!"

"Let me manually write down what the descriptor could be."

You then see a cat write down the descriptor on the whiteboard
