Claim 10:
11. A blockchain-based system for enforcing a smart contract on a network comprising one or more cryptographically-signed blocks, the system comprising:
a software application, the application operating on a mobile computer device or on a computer device, which is in communication with multiple securities lenders and securities borrowers, the application is configured to receive:
a securities financing report including:
a lender identifier associated with a unique lender,
a borrower identifier associated with a unique borrower,
an security identification number associated with a unique security, traded on an exchange, being lent by the unique lender to the unique borrower, and
a collateral identifier associated with an amount of cash or collateral securities provided by the unique borrower to the unique lender,
wherein the borrower identifier, the lender identifier, the security identification number and the collateral identifier define a unique transaction,

a minimum collateral value threshold previously uploaded by an employee or agent of the unique lender; and
a list of blockchains previously associated with previously identified security identification numbers; and

a processor in communication through the wired and/or wireless communication network with the software application, the processer is configured to:
compare the security identification number received by the software application with the security identification number on prior blockchains to identify a matching blockchain, and
generate and transmit to the matching blockchain an update hash containing an updated timestamp, an updated lender identifier, and updated borrower identifier and an updated collateral identifier;

wherein, the processor is further configured to monitor the value of the collateral identified by the last collateral identifier on the matching blockchain and when the value falls below the minimum collateral value threshold, within a range of tolerance, the processor is configured to issue an order recalling the securities associated with the security identification number to all borrower identifiers identified on the matching blockchain and instructing the exchange to prohibit any transfers of the securities to parties other than the first lender identifier identified on the matching blockchain.
