Comment Comment by aussieguy1234 Perhaps crypto should have a transaction delay with a user held reverse key for transactions above a certain user defined amount.If a transaction is above that amount, you get alerts by email, SMS, push notification...If it's expected you let it go though. If not, you take out the key, then reverse it.Of course legit recipients would wait until the delay period is over before considering the transaction to be complete.No worries if an attacker steals the key. Why would they reverse their own transaction? parent aussieguy1234 1 day ago
