Update: instead of checking the ownership of the specific satoshi, we will check that there exists a valid transaction of a specific format, where:

• the first input comes from a Taproot address
• the first input refers to a previously unspent Taproot transaction
• the previous output has the expected data in the witness field
• the output has the expected address as a receiver
• the pkscript contains the tweaked public key of the expected receiver
• both transaction have been included in the canonical chain
