1. A method performed by a digital computing apparatus, the digital computing apparatus being a smart contract validator, the method comprising:
receiving, from a quantum-safe (QS) validator via a communications network, a request to register a current transaction on a blockchain, the request comprising an indication of a payer, an indication of a payee, an indication of an item to be transferred, and an indication of a QS signature of the QS validator;
verifying the QS signature of the QS validator;
receiving, from the QS validator via the communications network, a new commitment value, the new commitment value being generated using a commitment mechanism on an unrevealed secret, the unrevealed secret being a committed secret associated with the current transaction and stored in the QS validator;
receiving, from the quantum-safe (QS) validator via the communications network, a revealed secret;
performing the commitment mechanism on the revealed secret to obtain a result;
validating the request by comparing the result to an old commitment value, the old commitment value being associated with a most recent previous transaction processed by the QS validator;
upon validation of the request, creating a transaction record based on the request, signing the transaction record, and submitting the transaction record for inclusion in the blockchain, wherein the transaction record comprises indicia of the payer, the payee, and the item to be transferred, and wherein the transaction record further comprises the new commitment value.
