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.
