Distributed Ledger Technology For Freight System
A system may receive a tracking update created by a tracking device. The tracking update comprising geographic location information indicative of a current geographic location of the tracking device. The system may identify, in a blockchain, a smart contract including executable logic configured to calculate a tracking metric. The system may determine, using the executable logic, the tracking metric in response to receipt of the tracking update. The system may append a datablock to the blockchain. The datablock may include the tracking metric and the geographic location information. The system may synchronize the blockchain with a plurality of blockchains stored in blockchain databases.

- 1. A method, comprising:
receiving, by a server node in communication with a blockchain database, a vehicle tracking update created by a vehicle tracking device, the vehicle tracking update comprising geographic location information indicative of a geographic location of the vehicle tracking device; identifying, in a blockchain stored in a database, a smart contract including destination identifier and executable logic configured to determine a tracking metric; determining the tracking metric in response to receipt of the vehicle tracking update by calculating, using the executable logic, the tracking metric based on a comparison of the geographic location information of the vehicle tracking update and previous geographic location information included in a previous datablock of the blockchain; appending a datablock to the blockchain, the datablock including the tracking metric and the geographic location information; determining a shipment associated with the vehicle tracking device has reached a destination corresponding to the destination identifier by detecting, using the executable logic and the vehicle tracking update, that at of at least one of the following conditions are satisfied:
the vehicle tracking device has remained stationary for a predetermined amount of time included in the smart contract, or
the vehicle tracking device is positioned in a geographic area, the geographic area identified by the smart contract; and
synchronizing the blockchain with a plurality of blockchains stored in blockchain databases remote to the server node.
- 8. A system, comprising:
a processor, the processor configured to: receive a tracking update created by a tracking device, the tracking update comprising geographic location information indicative of a geographic location of the tracking device; determine, using executable logic of a smart contract stored in a blockchain, the tracking metric in response to receipt of the tracking update; append a datablock to the blockchain, the datablock including the tracking metric; and synchronize the blockchain with a plurality of blockchains stored in respective blockchain databases configured at respective server nodes.
- 15. A non-transitory computer readable storage medium comprising computer executable instructions, the computer executable instructions executable by a processor, the computer executable instructions comprising:
instructions executable to receive a tracking update created by a tracking device, the tracking update comprising geographic location information indicative of a geographic location of the tracking device; instructions executable to determine, using a smart contract stored in a blockchain, the tracking metric in response to receipt of the tracking update; instructions executable to append a datablock to the blockchain, the datablock including the tracking metric; and instructions executable to synchronize the blockchain with a plurality of blockchains stored in blockchain databases.
