System and method for blockchain-based network transitioned by a legal contract

A system for a data-driven contract comprising:

• for each programmable clause of a set of programmable clauses stored on a non-transitory computer-readable storage medium,
• a template request defining data necessary to execute the programmable clause;
• and
• a template response defining data output by the programmable clause responsive to the template request;
• a blockchain distributed ledger network operated according to an application model that maps to a template model;
• an execution engine that executes contract data elements according to changes in the blockchain distributed ledger network;
• wherein the execution engine is configured to, in response to an update to a contract state of the data-driven contract, record an update to the blockchain distributed ledger network;
• and
• wherein in response to an update in the blockchain distributed ledger network that is contract-associated,
• the blockchain distributed ledger network is configured to initiate execution of at least one programmable clause of the data-driven contract, based on the template request of the at least one programmable clause;
• the blockchain distributed ledger network initiates execution of the at least one programmable clause of the data-driven contract at the execution engine using an external input;
• and
• based on the execution of the at least one programmable clause, the execution engine records a second update to the blockchain distributed ledger network, based on the template response of the at least one programmable clause.
