Abstract
A system and method for blockchain-based document processing includes a processor, network interface, print engine, scan engine, and a memory storing a blockchain ledger. The blockchain ledger includes time stamped blocks, each block including currency data associated with a digital currency value. The processor generates a block corresponding to a received instruction, a preexisting currency value associated with the received instruction and contract data corresponding to a smart contract associated with the received instruction. The processor updates the blockchain ledger with a generated block and shares an updated blockchain ledger with other networked data devices via the network interface. The processor also receives verification of the updated blockchain ledger from the other networked data devices. The processor executes the smart contract upon receipt of verification.
