Doesnt that require two transactions if you want the funds back?
Couldn't you just put the hash in witness data to save funds and make it part of any txn?
Had an idea for simple timestamps without OP_RETURN, just sending satoshis around:

This method counts probably as pure monetary use and not 'spam' 🫣
well but it‘s still unusable funds and „worthless“ tx in a monetary sense. how is this any different than putting a hash into op_return?
Op_return is for child molesters only 😶🌫️

why is it worthless and how is it unusable?
it pays fees to miners. this is identical to their main service: collecting fees to order things.
the person making the timestamp has the private key and can recover some of their funds (again, less the miner fee, as is proper).
ah sorry i thought the „hash“ adress is an arbitrary burner adress but i see now it‘s deterministic? that‘s pretty cool!
i built a consumer friendly tool for the same purpose using op_return: proofseal.org
point is to use as few "extra features" as possible.
