Learning about the blockchain cargo tracking system

Glossary

Term DefinitionBlockchain is a distributed database that uses cryptography to ensure data security and immutability. Smart Contract is a piece of code stored on the blockchain that is automatically executed when the preset conditions are met. Tracking Device is a device that can record and transmit cargo location information, such as a GPS tracker. Tracking Update is a data packet sent by a tracking device that contains cargo location information. Geolocation Information is data that describes the geographic location of cargo, such as longitude and latitude coordinates. Destination Identifier is a code or identifier used to uniquely identify the final destination of cargo. Tracking Metric is a metric used to measure the cargo transportation process, such as travel distance, transportation time, dwell time, etc. Data Block is the basic unit of the blockchain, containing transaction information and encrypted hash values. Origin Data Block is the first data block in the blockchain, containing initial information. Executable Logic is the code logic defined in the smart contract to perform specific operations. Logistics Control Stack Software system that manages and coordinates the cargo transportation process. Carrier A company or individual responsible for transporting cargo. Shipper A company or individual who entrusts a carrier to transport cargo. Transportation Contract Parameters Parameters that define the terms and conditions of a transportation contract, such as transportation routes, times, prices, etc. Tracking Table A data table used to record and update cargo tracking indicators. Report A document that contains a summary of cargo transportation information, such as transportation routes, times, costs, etc. Synchronization The process of ensuring data consistency between different blockchain nodes.

Short answer questions

Blockchain is a decentralized distributed ledger technology that can record and track data securely and transparently. In the cargo tracking system, blockchain can ensure that data is secure and cannot be tampered with, improve information transparency, and reduce disputes and fraud.

Smart contracts are self-executing contracts stored on the blockchain, which can automatically execute operations such as payment and transfer of cargo ownership according to preset conditions. In the cargo tracking system, smart contracts can automatically execute contract terms, improve efficiency, and reduce labor costs.

Tracking devices interact with the blockchain system by regularly sending tracking updates containing the geographic location information of the cargo. This information will be recorded on the blockchain to form a complete cargo transportation track.

Tracking indicators are quantitative data used to measure various indicators in the cargo transportation process, such as travel distance, transportation time, dwell time, cargo temperature, humidity, etc.

Each data block contains the encrypted hash value of the previous data block, linking all data blocks in chronological order to form an unalterable blockchain.

The origin data block is the first data block in the blockchain and contains initial information, such as smart contract content, participant information, etc.

The logistics control stack is the core of the blockchain cargo tracking system, responsible for receiving and processing data sent by tracking devices, executing smart contracts, generating reports, etc.

"Handover" refers to the process of transferring goods from one carrier to another during transportation, or from a carrier to the final consignee. Each handover will be recorded on the blockchain to ensure the integrity of cargo tracking.

The blockchain system needs to be synchronized to ensure data consistency of all nodes and prevent data conflicts and tampering.

The blockchain cargo tracking system can generate various types of reports, such as cargo location reports, transportation time reports, cost reports, abnormal event reports, etc., to provide data support for supply chain management.
