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 (100) for distributed shared execution of one or more shared processes, comprising: first program code for the one or more shared processes that comprises one or more shared code segments (142, 144, 146) shared between a first authorizing node (102) and a second authorizing node (104), wherein the one or more shared code segments (142, 144, 146) are executable by one or more executing nodes (102, 104, 106); a distributed ledger (152, 154, 156) that provides a record of valid code segments of the program code; and second program code comprising instructions that, when executed by the first and/or second authorizing nodes, validates that an anticipated execution result of the one or more shared code segments (142, 144, 146) satisfies shared authorization conditions and, if satisfied, authorizes the execution of the one or more shared code segments by the one or more executing nodes.

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 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 method of scheduling and validating a multiple-participant process, the method including: submitting, by a submitting node associated with a participant in the multiple-participant process, a proposed transaction by sending a cryptographically-protected message to one or more recipient nodes, wherein the cryptographically-protected message includes at least an unencrypted submessage readable by an external node and a cryptographically-protected submessage to preserve privacy from at least the external node; determining, by the external node, an order of the proposed transaction relative to other transactions; by way of at least some of the recipient nodes, validating the cryptographically-protected message; receiving a confirmation of validity of the cryptographically-protected message from at least some of the recipient nodes; finalizing the proposed transaction, as a confirmed transaction, based on receiving one or more confirmations from at least some of the recipient nodes that satisfy a confirmation co

Abstract: A database system (1) and method (100) comprising a database system memory (3) and at least a first database server (9). The database system memory (3) stores a database of data records (7) and shared program instructions (51) between first and second database users (21, 31). The shared program instructions (51) define a privacy model (13) comprising privacy restrictions (14, 23, 33) for the first and second database users (21, 31), respectively, and specify an authorization model (19) comprising a first set of authorizations (25?, 35?) that permit the first database user (21) to manipulate a first subset (27) of the data records consistent with the first user's privacy restrictions (23?, 33?) and a second set of authorizations (25?, 35?) that permit the second user (31) to manipulate a second subset (37) of the data records consistent with the second user's privacy restrictions (23?, 33?).
