A method is disclosed for verifying a correctness of a result of an electronic activity on a communications network and having one or more cryptographic related processes for verifying the correctness, where the activity is among a plurality of parties and the activity results in an exchange of a monetary asset. The method includes receiving first information for securing first data from being changed, where the first data (i) is used in performing the activity by the parties, and (ii) identifies one or more values for applying one or more predetermined machine encoded constraints related to performing the activity. During, and prior to a termination, of the activity, the method further includes, for a first of the parties, obtaining second information for a data collection including the first data, the second information not being available to any of the parties for affecting the activity prior to an event terminating the activity. The method verifies the correctness of the result of the activity using the one or more of the cryptographic related processes for independently verifying the result correctness.
