Abstract: A cryptographic representation of value is adapted to goods in production and products at various stages through a supply chain as represented by their stock keeping units or SKU's that refer to a unique identifier or code for the particular stock keeping unit. Embodiments of the invention disclose the generation of a universal unique, yet deterministic, key-pair for all SKUs, shipping cartons, and items, i.e. for every single SKU, shipping carton and item on the globe.

Abstract: A cryptographic representation of value is adapted to goods in production and products at various stages through a supply chain as represented by their stock keeping units or SKU's that refer to a unique identifier or code for the particular stock keeping unit. Embodiments of the invention disclose the generation of a universal unique, yet deterministic, key-pair for all SKUs, shipping cartons, and items, i.e. for every single SKU, shipping carton and item on the globe.

Abstract: Various embodiments include a method of tracking a chain of custody of an item in a supply chain. A computer system implements a computer interface with a distributed consensus network comprised of computing devices configured to verify one or more waiting transaction records for addition into one or more blocks in a block chain representing a cryptographically verifiable ledger. The order of the block chain is cryptographically protected against tampering by the computing devices. The computer system can track provenance of the item by identifying an existing record in the block chain. The existing record can place a first quantity of a first stock keeping unit (SKU) at a first address. The computer system can then unitize the item by publishing a new record to the block chain. The new record indicates the existing record as a source record and associates a new SKU with a destination address.

Abstract: Some embodiments include a system for tracking end-to-end provenance of labeled goods despite re-unitization, repackaging, or transformation of the goods. The system can mint cryptographic codes including a first cryptographic code and a second cryptographic code. Each cryptographic code can include a private key to serve as a label and a public key that serves to identify a cryptographic address in a distributed consensus network. The system can track a source item by publishing a first cryptographically verifiable record that associates an original SKU and an original quantity with a first cryptographic address associated with the first cryptographic code. The system can re-unitize the source item by publishing, to the distributed consensus network, a second cryptographically verifiable record that indicates the first cryptographically verifiable record as a source and associates a new SKU and a new quantity with a second cryptographic address associated with the second cryptographic code.
