Decentralized Vehicle-to-Everything (D-V2X)

Decentralized vehicle-to-everything (D-V2X) is a label for proposals that combine vehicle-to-everything communication, in which cars exchange information with other vehicles, traffic lights, roadside units, charging stations and networks, with blockchain-based record-keeping and payments. Conventional V2X systems are run by carmakers, telecom operators or road authorities; D-V2X designs aim to let vehicles hold their own digital identity, share data with consent and settle small payments for tolls, parking, charging or data automatically, without one company controlling the platform. The idea overlaps with the Internet of Things and with DePIN projects that reward drivers for sharing vehicle data. As of November 2026 it remains largely at the research and pilot stage, with open questions about speed, safety certification and data privacy. Also see microtransactions.
