Model Checking Correctness Properties of Electronic Contracts (2003)

Author(s): Solaiman E, Molina-Jimenez C, Shrivastava S

    Abstract: Converting a conventional contract into an electronic equivalent is not trivial. The difficulties are caused by the ambiguities that the original human-oriented text is likely to contain. In order to detect and remove these ambiguities the contract needs to be described in a mathematically precise notation before the description can be subjected to rigorous analysis. This paper identifies and discusses a list of correctness requirements that a typical executable business contract should satisfy. Next the paper shows how relevant parts of standard conventional contracts can be described by means of Finite State Machines (FSMs). Such a description can then be subjected to model checking. The paper demonstrates this using Promela language and the Spin validator.
