Abstract: Various embodiments of a system and method for capturing changes in trade information that impact trade authorization and for updating a chain state on a distributed chain database that is used to authorize trades are disclosed herein. In some embodiments, the system comprises: a trade controller configured to obtain a current state from a local database; a rules engine configured to be invoked by the trade controller to apply a ruleset to data extracted from the local database to generate an updated state; an operation auto detector configured to generate a plan to update a chain state on the distributed chain database based at least in part on the updated state; and an execution engine configured to execute the plan and to generate an updated chain state that is used to authorize trades.

Abstract: Various embodiments of a technique to securely process and transfer a token in a distributed chain database are described herein. The technique includes receiving a valid call to a transfer function to execute a transfer, intercepting the transfer function call and routing a check function to an authorization service that is executed on a chain database, and determining in the authorization service whether the transfer is authorized. The authorization service includes a state that is controlled by a process that is executed off the chain database and returns a value that indicates whether the transfer can proceed. The system then determines whether to validate or invalidate the transfer in response to the returned value.
