Decentralized Vehicle-to-Everything (D-V2X)

Hard

D-V2X operates on a peer-to-peer network where nodes maintain copies of a decentralized ledger, ensuring data integrity and trust among participants in the network.

What Is Vehicle-to-Everything (V2X)?

Most people imagine their cars as one machine, but as we have developed better technologies these have been integrated into vehicles to improve our experiences on the road - mainly by having cars communicate with each other and improve safety and efficiency on the roads. This is called Vehicle-to-everything (V2X).

Vehicle-to-everything (V2X) is part of the broader Internet of Things (IoT) ecosystem. It can be split among specific communication partners such as vehicles (V2V), pedestrians (V2P), infrastructure (V2I), and networks (V2N). 
Current V2X technologies are WLAN-based or cellular-based. However, V2X technology faces barriers to wider adoption due to a lack of interoperability between centralized vehicular systems, trust and security vulnerabilities, and expensive infrastructure. 

What Is Decentralized Vehicle-to-Everything (D-V2X)?

Decentralized V2X (D-V2X) is the incorporation of blockchain technology into the V2X stack. 

D-V2X operates on a peer-to-peer network where nodes maintain copies of a decentralized ledger, ensuring data integrity and trust among participants in the network.  

As such, the decentralization of V2X addresses some key roadblocks. Specifically, building this technology onchain can ensure a single location for secure data exchange, a tamper-proof repository, and a scalable foundation. 

Better Security

By bringing this data onchain, multiple parties can interact with it, removing the varied structures and designs currently found with each car manufacturer or company implementing V2X.

While providing a unified home base for this data, it also removes the risk of a single point of failure.  While a centralized system can be shut down by those running it, the peer-to-peer model of D-V2X means that if one node is shut down or attacked the V2X network continues without disruption. This is key in the case of a public transport system which could bring a city to a standstill if it were compromised.  

Trust and Scalability

With the assistance of smart contracts, enforcing rules related to how the data is supplied, secured, and automated. It also ensures that only verified users can participate in the D-V2X ecosystem. 

Not having intermediaries or relying on a centralized entity makes the platforms more scalable. There are serious upper limits to a server for user data that are not present with scalable blockchain solutions as more nodes can be added to carry and support the heavier burden.

Since the goal of V2X implementation is to have all vehicles able to talk to each other, there is a significant need for systems that can handle a city or a country’s worth of users, devices, and data.

Privacy

Data privacy is still in its infancy, with many people still freely supplying data to companies to be used and shared without much protection. However, there is an increase in awareness, and a system like V2X will need to rely on credibly securing user data. 

While the blockchain is known for its transparency, implementing other cryptographic solutions like zero-knowledge proofs can ensure users' data is still usable and useful without compromising their privacy.

Zero-knowledge (zk) technology allows for verification of a user or, in this case, their vehicle, without having to release the actual data publicly.

V2X and other similar physical infrastructure networks are the perfect use case for this technology because of the need to ensure user data is only shared when necessary and with their permission. 

The inclusion of this technology in D-V2X also can allow for customization of data sharing with users opting in to share only what they are happy with contributing. 

Ownership 

Alongside being able to contribute data with ensured privacy, the decentralization of V2X networks can enhance community participation. 

With D-V2X there is the possibility of rewarding users with tokens that convert them from a simple supplier to a stakeholder in the network. This can increase participation and greatly improve communication across transport network participants including drivers, manufacturers, and governments. 

The Goal of D-V2X

Overall the goal of D-V2X technology is to take the data-sharing and interconnectedness of V2X and make it more viable, trustworthy, and ultimately permissionless. 

With the improvements brought by decentralization, implementation of D-V2X could mean seeing smart transport systems optimizing traffic, improving transport systems, and having people benefit from their own vehicle’s data. The knock-on effects include lowering accident rates, making smarter cities, and a more cooperative data-sharing world. 

With the removal of a centralized point of failure and a single communication platform, there are increased opportunities for the development and implementation of V2X.
