Abstract: A system for validating the integrity of blockchain transactions prior to such transactions being added to the electronic blockchain using, in part, an automated, protocol-based methodology is disclosed. Use of such a system circumvents current costly consensus mechanisms for validating transactions prior to inclusion onto the underlying electronic blockchain. In a preferred embodiment, the disclosed system may be implemented within blockchain environments where the transacting parties “trust” each other where trust may be evidenced in different ways. In such an example, the system provides an automated, protocol-based validation of transactions that have been approved by the transacting parties, such that record of the validated transaction may be appended to a blockchain.

Abstract: A system for tracking and recording the chain-of-custody for assets within a supply chain that creates a non-repudiatable electronic log of each custody transfer at each transfer point from initial creation, to final transfer or disposal. In one embodiment, the system uses encryption technology to register assets that are to be transferred and whose chain of custody is to be ensured. Through use of encryption key pairs and blockchain encryption technology, an electronic document is created in an encrypted transaction log updated at each change of custody point. At each such change of custody point, the new custodians who receive the product are provided with the information generated by the originator. By way of one example, because the system tracks all inputs and outputs to the system at each change of custody point, any alteration in product quantities are immediately identified, and a chain-of-custody integrity problem is identified.
