Optimistic Asynchronous Multi-Party Contract Signing

  title={Optimistic Asynchronous Multi-Party Contract Signing},
  author={Thomas J. Watson},
A contract is a non-repudiable agreement on a given contract text, i.e., it can be used to prove unanimous agreement between its signatories to any veri er. A contract signing protocol is used to fairly compute a contract so that, even if n 1 of the n signatories misbehave, either all or none of them obtain a contract. Optimistic contract signing protocols use a third party to ensure fairness, but in such a way that the third party is not actively involved in case all parties are honest. Since… CONTINUE READING
