Of course there is proof. The buyer and seller can cryptographically sign any message attached to the to and from addresses. Easy.
Careful — Don’t fall for the bullshit that shitcoin teams peddle to convince people to part with their sats. (Yes, eth is a shitcoin)
can that message be not encrypted? so that everyone can verify that the house actually belongs to the owner of the wallet that sent the transaction?
Not defending or protesting any protocol. Just discussing different technologies and their different possible uses.
Yeah. A cryptographic proof is something that everyone can verify. That’s why the bitcoin motto is “don’t trust, verify”
Cryptographic proof is not encryption.
