Say you have a private key & public key pair xy. If I find a collision such that a new private key z that has same public key y I CAN sign transactions as you. By signing the a transaction (involving your bitcoins) w/ key z they would be validated by the network just as they would if signed by x. Both would appear equally valid. Only your last paragraph is wrong. If you modify the answer I will remove downvote. | |
