Claim:
1. A computer-implemented method comprising: implementing a computer interface with a distributed consensus network comprised of computing devices configured to verify one or more waiting logistic records for addition into one or more logistic record blocks in a block chain representing a cryptographically verifiable ledger, wherein the order of the block chain is cryptographically protected against tampering by the computing devices; tracking provenance of an item in a supply chain by at least identifying a sequence of inter-referencing cryptographically verifiable records having linking pairs of cryptographic addresses in the block chain, wherein the cryptographically verifiable records includes a first cryptographically verifiable record in a first block along the block chain, wherein the first cryptographically verifiable record places a first quantity of a first stock keeping unit (SKU) at a first cryptographic address; minting a cryptographic code comprising a private key associated with a label and a public key that identifies an unassigned cryptographic address in the cryptographically verifiable ledger, wherein ownership of the unassigned cryptographic address is verifiable via a cryptographic signature of the private key; distributing the private key to be embedded into a physical label for the item; and unitizing the item by publishing a second cryptographically verifiable record to a second block along the block chain, wherein the second cryptographically verifiable record indicates the first cryptographically verifiable record as a source record and associates a new SKU with a second cryptographic address, wherein a plurality of transfer records, including the first cryptographically verifiable record and the second cryptographically verifiable record, in the cryptographically verifiable ledger indicates a chain of custody of the item, wherein the second cryptographic address corresponds to the cryptographic code; wherein a difference of SKU type between the first SKU in the supply chain of the item to the new SKU in the supply chain of the item denotes a repackaging or transformation of a group of goods including the item in between a transfer of custody.
