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: A computer system comprising: a global synchronization log that stores public data associated with private data wherein the private data is stored in one or more private data stores separate from the global synchronization log; and one or more nodes operable in a mode as a writer node that has access to write the public data associated with private data to the global synchronization log. A reader node may verify the public data on the global synchronization log with private data stored in one or more private data stores.

Abstract: A computer system (100) comprising: a global synchronization log (112) that stores public data associated with private data wherein the private data is stored in one or more private data stores (132, 134) separate from the global synchronization log (112, 114); and one or more nodes (102) operable in a mode as a writer node (102) that has access to write the public data associated with private data to the global synchronization log (112). A reader node (120) may verify the public data on the global synchronization log (112, 114) with private data stored in one or more private data stores (132, 134).

Abstract: A system and method are provided for executing multilateral transactional bookkeeping workflows between a plurality of participants, including receiving previously agreed and formalized rules, receiving an authorized decision, evolving an agreement based on the authorized decision and the rules, notifying participants in the agreement of the evolved agreement, and storing the evolved agreement with evidence of notification in a shared append-only ledger.
