Short Answer Key:

PAAV stands for Pathway-Article Assisted Vehicle. Unlike traditional vehicles, PAAVs utilize a vision system and onboard computing to interpret pathway information embedded in articles like road signs and markings.

A blockchain provides a secure, tamper-proof system for storing authentication and pathway information associated with each article. This helps PAAVs validate the authenticity of the information they receive.

"Authentication information" verifies the legitimacy of a pathway article (e.g., unique identifier), while "pathway information" provides instructions or details about the pathway itself (e.g., speed limit, curve ahead).

The "code," often a 2D barcode like a QR code, acts as a machine-readable link to the blockchain. It contains authentication information about the article, potentially including a unique ID, location, and type.

The PAAV scans the code on the article and compares the embedded authentication information with the information stored on the blockchain. A match confirms authenticity.

Actions may include ignoring the counterfeit article's instructions, maintaining current operation based on other sensors, displaying a warning to the occupant, or transmitting an alert to relevant authorities.

Storing pathway information on a blockchain allows for redundancy and reduces reliance on individual PAAV sensors. This can improve accuracy, especially in challenging conditions, and potentially lower manufacturing costs.

The "article registration API" enables the registration of new pathway articles onto the blockchain, while the "write properties API" allows authorized entities to add or modify information associated with those articles.

Vehicles within the consensus network can host a copy of the blockchain. This allows them to directly authenticate articles or act as a data source for other PAAVs seeking authentication.

Mobile construction devices allow for on-site creation and modification of pathway articles. This is particularly useful for temporary situations like construction zones, road closures, or dynamic environments like warehouses.
