Methods and apparatus for performing agricultural transactions
View Patent ↗Systems, apparatus, and methods for transacting, recording, validating and/or verifying agricultural products and its proceeds. The 2018 Farm Act rescinded industrial hemp from Schedule I of the Controlled Substances Act (CSA). Although industrial hemp has a variety of uses, the Government's biggest concern is the ingestion of tetrahydrocannabinol (THC) and cannabidiol (CBD). Commercial regulation typically balances a variety of factors: e.g., consumer protection, regulatory overhead, market competition, tax revenue, public policy, etc. In contrast, law enforcement has a singular purpose, and may go to extraordinary lengths to stop criminal activity. Various embodiments described herein provide a blockchain ledger-based supply chain that allows many commercial and regulatory entities to independently cooperate. Every transaction is permanently and transparently recorded within a chain-of-custody; the chain-of-custody enables a traceability; transitive linkages enable regulatory compliance. A variety of new applications are enabled by the blockchain ledger-based supply chain.
1. A method for chain-of-custody management, comprising:
generating a code for a consignment;
associating the code to a package via a distributed ledger;
locking the package with a ledger lock during a delivery;
in response to receiving a first record for the code from a first bailor, verifying the first record; and
updating the distributed ledger with the first record when successfully verified.
2. The method of claim 1 , further comprising locking the package with a first bailor specific lock while in possession of the first bailor during a first portion of the delivery.
3. The method of claim 1 , further comprising:
in response to receiving a second record for the code from a second bailor, verifying the second record;
updating the distributed ledger with the second record when successfully verified; and
locking the package with a second bailor specific lock while in possession of the second bailor during a second portion of the delivery.
4. The method of claim 3 , where the second record releases the first bailor of a constructive custody.
5. The method of claim 3 , where the first bailor and the second bailor both have constructive custody during a common portion of the delivery.
6. The method of claim 1 , where verifying the first record comprises ensuring that a chain-of-custody protocol was followed.
7. The method of claim 6 , where the chain-of-custody protocol comprises checking a source, a destination-on-file location, or a delivery route of the first bailor based on a real-time geospatial proximity.
8. The method of claim 7 , where checking the source comprises checking a unique lot identifier that is associated with a geospatially identified crop location.
9. The method of claim 1 , further comprising validating the first record and updating the distributed ledger with the first record when successfully validated.
10. The method of claim 9 , where validating the first record comprises measuring a characteristic of the package to validate objective conformance.
11. The method of claim 10 , where measuring the characteristic comprises weighing the package.
12. The method of claim 10 , where measuring the characteristic comprises testing for a varietal, breed, genus, genetic lineage, or genomics.
13. The method of claim 10 , where measuring the characteristic comprises checking a record of temperatures, humidity, vibration, radiation, or climate.
14. A server apparatus, comprising:
a network interface;
a processor; and
a non-transitory computer-readable medium comprising instructions that when executed by the processor, causes the server apparatus to execute a distributed ledger application that participates in a consensus mechanism to:
assign a code to a consignment;
associate the code to a package;
lock the package with a ledger lock during a delivery;
verify a first record provided by a first bailor; and
update a chain-of-custody for the package with the first record when successfully verified.
15. The server apparatus of claim 14 , where the non-transitory computer-readable medium further comprises a first copy of a distributed ledger data structure and where the network interface is configured to communicate with a plurality of other servers that each maintain a corresponding copy of the distributed ledger data structure.
16. The server apparatus of claim 15 , where the chain-of-custody for the package is updated such that the first bailor assumes a first virtual custody of the package.
17. The server apparatus of claim 16 , where the chain-of-custody for the package includes at least a second bailor that remains in a concurrent virtual custody of the package.
18. The server apparatus of claim 16 , where the plurality of other servers comprises a second server that maintains a second copy of the distributed ledger data structure, and where the second server is controlled by the first bailor.
19. The server apparatus of claim 16 , where the plurality of other servers comprises a forensic accounting entity that maintains a second copy of the distributed ledger data structure and where the network interface is further configured to notify the forensic accounting entity when a second record is unsuccessfully verified.
20. A system, comprising:
a plurality of servers that each maintain a copy of a distributed ledger data structure; and
where the plurality of servers are configured to execute a distributed ledger application that participates in a consensus mechanism to:
generate a code for a consignment;
associate the code to a package via a distributed ledger;
lock the package with a ledger lock during a delivery;
in response to receiving a first record for the code from a first bailor, verify the first record; and
update the distributed ledger with the first record when successfully verified.
