In the smart property scenario presented, where Alice sells her car to Bob via an atomic transaction:
| Requires modifications to Bitcoin because there is no way for two different people who don't trust each other to securely sign the same transaction | Wrong |
| Alice and Bob must be physically near the car for the transfer of control to take effect | Wrong |
| Bob must make sure that Alice deletes her private key so that she does not retain the ability to activate the car | Wrong |
| The protocol doesn't prove to Bob, before the sale, that the transaction output that Alice wants to sell him actually corresponds to the car he wants to buy | Correct |
