1. A method for inter-linking dependent processes across multiple parties using smart contracts, comprising:
a back end for a lending financial institution receiving a first communication comprising an identification of a vehicle being purchased with a loan and an identification of an insurer that insures the vehicle;
the back end for the lending financial institution generating a smart contract that directs the back end to restrict access to the vehicle in response to the vehicle not being covered by insurance;
the back end for the lending financial institution writing the smart contract to a ledger as a first block in a linked transaction chain;
the back end for the lending financial institution receiving, from the ledger, notice that the vehicle is no longer insured in a second block in the linked transaction chain written by the insurer; and
the back end for the lending financial institution automatically executing the smart contract, wherein automatically executing the smart contract causes a communication with the vehicle that disables the vehicle.
