&gt; Your bitcoin payment is only as safe as your ability to reliably bind a bitcoin address to an intended recipient. If you get it wrong, there&#x27;s no recourse.<p>Maybe im being totally naive.. but how about a second blockchain called the &quot;rollback&quot; blockchain.. Suppose you put a &quot;timer&quot; in the bitcoin blockchain for a period lets say 48 hrs..<p>So when the timer expires, the first blockchain(the coin blockchain), would check for a &quot;rollback transaction&quot; in the second one.. if its not there, the transaction on the first blockchain would be confirmed, and the funds would go to te right account, in a completely automated way, with all the trust garantee that the blockchain tech can give.<p>Is this a stupid idea? (i just gave a quick tought about this)<p>OBS: of course, say goodbye to instant payment.. but with double check security sugar on top of it.
