Abstract: A system and method for tracking the provenance of an item, service, and/or payment is provided. The system includes a transaction processing system for generating and recording a provenance transaction that includes information to track the provenance of an item, service, transformation, and/or payment; a blockchain interface for facilitating communication with a blockchain, the blockchain interface configured to store the provenance transaction on the blockchain and to retrieve the provenance transaction from the blockchain; and a search and provenance graph system for generating a directed graph to represent the provenance of an item, service, and/or payment using the provenance transaction stored on the blockchain.

Abstract: Blockchain applications can generate public/private key pairs without knowing the true identity of the owner of the private key. Many applications, such as in healthcare or corporate banking, require known identities for legal or regulatory reasons. Therefore a mapping between PKI certificate credentials maintained by certificate authorities and blockchain credentials is needed as one means of transferring real-world identity to blockchain applications. A method and system are provided to associate a PKI certificate to one or more accounts in a cryptographic wallet and extend the due diligence of a third-party certificate authority for identity management on blockchains.
