Abstract: Computer-implemented methods and systems are provided for a procurement system. Consistent with disclosed embodiments, the procurement system may include at least one processor and at least one non-transitory memory containing instructions that, when executed by the at least one processor, cause the procurement system to perform operations. The operations may include creating, in a blockchain, a contract corresponding to a procurement request including a first procurement parameter, the contract including contract code enforcing procurement obligations. The operations may include receiving, from at least one user system, at least one additional procurement request including at least one second procurement parameter and indicating the contract. The operations may also include generating a contract execution result by executing the contract code using the first procurement parameter and the at least one second procurement parameter; and updating the blockchain based on the contract execution result.
