Systems and methods for item-level adjudication

A system for omni-channel item-level promotional offer adjudication, the system comprising:

• a distributed ledger comprising:
• a plurality of nodes;
• a transaction log comprising a list of coupon codes and an indication of whether each of the coupon codes has already been redeemed;
• and
• a consensus algorithm configured to synchronize the transaction log to ensure that all copies of the transaction log are identical across the plurality of nodes;
• a first retail system comprising a first payment module and at least one of:
• a first POS system;
• and
• a first cloud-computing system;
• a second retail system comprising a second payment module and at least one of:
• a second POS system;
• and
• a second cloud-computing system;
• and
• an adjudication module that enables each of the first retail system and the second retail system to access the distributed ledger, the adjudication module comprising at least one of:
• an integrated container comprising application code;
• and
• an API configured to allow the retail system to interface with the adjudication module,
• wherein the adjudication module interfaces with each of the first retail system and the second retail system, and wherein the adjudication module is configured to:
• receive and store item-level information relating to one or more inventory items for which use of a one-time-use coupon code is authorized;
• receive a purchase request comprising a payment amount and information concerning an item for purchase;
• receive a one-time-use coupon code;
• and
• read the transaction log of the distributed ledger to check whether the one-time-use coupon code has already been redeemed,
• wherein if the one-time-use coupon code has not already been redeemed, and if the information concerning the item for purchase matches the item-level information for which use of the one-time-use coupon code is authorized, the adjudication module applies the one-time-use coupon code to the purchase request to apply a discount to the payment amount, but if the one-time-use coupon code has already been redeemed, or if the information concerning the item for purchase does not match the item-level information for which use of the one-time-use coupon code is authorized, the adjudication module does not apply the one-time-use coupon code to the purchase request.

• a retail system comprising a payment module;
• and
• an adjudication module that enables the retail system to access the distributed ledger,
• wherein the adjudication module is configured to execute a security protocol comprising:
• generating a KAES;
• generating an asymmetric key pair comprising a skECC and a pkECC;
• encrypting a payment using the KAES;
• signing a code using the skECC;
• distributing the pkECC to the retail system;
• and
• distributing the code to the retail system.
