Abstract
Systems and methods are disclosed for manipulating and accessing a blockchain containing coupon authentication information for coupon processing services to process a coupon maintained by a network of nodes including a first node and a second node. A method may include generating, by the first node, a first coupon transaction that includes a smart coupon contract and broadcasting the first coupon transaction to the second node communicatively coupled to the network. The second node is configured to apply a set of consensus rules to validate the smart coupon contract included in the first coupon transaction prior to adding the first coupon transaction onto the blockchain, causing any one of the network of nodes to execute the smart coupon contract against input data after the first coupon transaction is validated and added onto the blockchain.
