Abstract: A system and method are provided for modeling and interpreting a modeled digital asset and its evolution with respect to the rights of a plurality of parties, the method comprising: executing an await function instance no more than once using one of at least one choice defined therein for disposition of the digital asset with respect to the rights of at least one of the plurality of parties, said await function instance incorporated upon the consent of the affected parties to fulfil a configured function instance associated with the at least one choice; executing an agree function instance that requires the consent of at least one of the plurality of parties to execute; and storing the results of the executed function instances in an append-only ledger.

Abstract: A system and method for selectively transmitting cryptographically signed information to a limited number of parties of an agreement using one or more processors. For each party affected by a decision of a first party, the processors generate a token according to a function of both (i) a cryptographic key of the given party and (ii) a cryptographic key of a second party, and transmit to respective private data stores of each party (a) the first party's decision, (b) the generated token, and (c) an identity of the second party. The decision of the first party and the generated tokens are transmitted to the private data stores of only the parties that are affected by the decision of the first party.

Abstract: Some embodiments are directed to a system that includes multiple fire sensors and equipment, and mobile devices of the users of the system. These fire sensors and equipment are configured in a network so as to allow communication with a processor. A processor in the system interrogates the status of the fire sensors and fire safety elements on a continuous basis. Upon a change in system status, the processor interprets the change and classifies according to operation state or probability of a fire or other imminent threat. The data, processing and storage provide the means by which occupants and potential occupants can better navigate a building during the occurrence of a fire.
