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.

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; andunitizing 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. 2. The computer-implemented method of claim 1, further comprising: verifying provenance of the new SKU by following the sequence of inter-referencing cryptographically verifiable records in the block chain to the second cryptographically verifiable record. 3. The computer-implemented method of claim 1, further comprising maintaining an electronic database that maps identities of entities to one or more entity-specific cryptographic addresses addressable in the cryptographically verifiable ledger. 4. The computer-implemented method of claim 1, wherein the first SKU represents at least a portion of the item, a package containing a form of the item, a previous form of the item, or any combination thereof. 5. The computer-implemented method of claim 3, wherein the first cryptographic address is associated with a first entity in the electronic database and the second cryptographic address is associated with a second entity in the electronic database. 6. The computer-implemented method of claim 3, wherein the first cryptographic address and the second cryptographic address are both associated with a first entity in the electronic database. 7. The computer-implemented method of claim 3, wherein an entity identifier in the electronic database is associated with multiple cryptographic addresses in the block chain. 8. 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 identifying an existing record in the block chain, wherein the existing record places a first quantity of an original stock keeping unit (SKU) at an existing 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; andunitizing the item by publishing a unitization record to the block chain, wherein the unitization record indicates the existing record as a source record and associates a new SKU and a new quantity at a destination address in the cryptographically verifiable ledger, wherein transaction records, including the existing record and the unitization record, in the block chain updates a chain of custody of at least an item between one or more linking pairs of cryptographic addresses;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. 9. The computer-implemented method of claim 8, further comprising: receiving a request to unitize, wherein the request to unitize designates the new quantity of the new SKU at the destination address; andauthenticating the request to unitize by verifying that the request to unitize includes a cryptographic signature corresponding to the new address, wherein said unitizing the item is in response to authenticating the request to unitize. 10. The computer-implemented method of claim 9, wherein the request to unitize designates multiple existing cryptographic addresses, including the existing address, corresponding to multiple old SKUs from which the new SKU is unitized from. 11. The computer-implemented method of claim 9, further comprising authenticating the request to unitize the item by verifying that the request to unitize includes a cryptographic signature corresponding to the destination address, and wherein the unitization record is published responsive to authenticating the request to unitize. 12. The computer-implemented method of claim 8, wherein each block in the block chain contains one or more transaction records and each block, except for a block at the beginning of the block chain, contains a hash value generated by processing content in a previous block via a hash function. 13. The computer-implemented method of claim 8, wherein a unit of the new SKU includes at least a subdivision of a unit of the original SKU or at least multiple units of the original SKU. 14. The computer-implemented method of claim 8, further comprising computing a directed acyclic graph from one or more cryptographically verifiable records, including the unitization record and the existing record, of the block chain to generate an audit trail for the chain of custody of the item. 15.
