Alice sells the private key of her Ethereum wallet to Bob. Bob pays through UTRUST. Alice is notified that the money is in escrow and sends the private key to Bob. Bob claims the key does not work. Alice opens a dispute.
Tell me how the UTRUST Mediator resolves this transaction.
I think this situation is impossible. No one buys private key of Ethereum wallet from others. Because the key cannot be changed. How can they use this wallet if the old owner still has private key?
Proving the point that whoever is saying escrow will ensure safe transactions is underestimating the complexity of transactions. That is why I am surprised that the UTRUST whitepaper contains so few details about their distinguishing features, the escrow and arbitration mechanism. It is not only about the code and tech, UTRUST need to teach their mediators protocols to solve difficult situations. And the most difficult of them all, the unsolvable situation.
