The convergence of blockchain-inspired technologies and the automotive industry took a bold step forward at CEBIT '18, where IOTA and Volkswagen unveiled a groundbreaking proof-of-concept (PoC) for connected and autonomous vehicles. This collaboration demonstrated how IOTA’s unique distributed ledger technology—Tangle—can enable secure, feeless data transmission and software updates in next-generation smart cars.
As the world moves toward intelligent transportation systems, the need for scalable, secure, and efficient data exchange between vehicles, manufacturers, and infrastructure is more critical than ever. The IOTA and Volkswagen PoC offers a compelling vision of this future, leveraging cutting-edge technology to address real-world challenges in vehicle connectivity and digital trust.
A New Era of Connected Car Technology
On June 11 at CEBIT '18 in Germany, Volkswagen and IOTA presented a live demonstration of their joint concept: using IOTA’s Tangle architecture to wirelessly deliver over-the-air (OTA) software updates to connected vehicles. Unlike traditional blockchain systems that rely on blocks and mining, Tangle operates on a Directed Acyclic Graph (DAG) structure. This allows transactions to be processed in parallel across multiple chains within the network, eliminating bottlenecks and enabling high scalability.

This design makes Tangle especially well-suited for Internet of Things (IoT) environments—such as fleets of smart vehicles—where thousands of micro-transactions occur every second. With no transaction fees and low computational overhead, Tangle supports seamless communication between devices, paving the way for autonomous systems that can securely share data, authenticate updates, and even make machine-to-machine payments.
Securing the Future of Smart Mobility
Volkswagen’s vision extends beyond simple software updates. The company aims to build a secure, decentralized ecosystem for intelligent mobility, where vehicles can autonomously interact with charging stations, toll systems, parking facilities, and other cars—all without human intervention.
In this envisioned smart car economy, Tangle serves as the backbone for trusted data distribution. For example:
- A self-driving car could automatically pay for electricity at a charging station using microtransactions.
- Vehicles could securely exchange real-time traffic or hazard data with nearby cars.
- Manufacturers could push critical safety updates instantly and verify their installation across global fleets.
Industry projections suggest that by 2025, more than 250 million connected vehicles will be on the road worldwide. Each of these vehicles will generate vast amounts of data and require frequent remote updates—making scalable, tamper-proof infrastructure essential. The IOTA-Volkswagen PoC directly addresses these demands, offering a decentralized solution that ensures both security and efficiency.
Expanding into Mobility-as-a-Service (MaaS)
Beyond vehicle-to-manufacturer communication, IOTA is also being explored for integration into broader Mobility-as-a-Service (MaaS) platforms. These systems aim to unify various forms of transport—ride-sharing, public transit, bike rentals, and private vehicles—into a single digital ecosystem.
With IOTA’s distributed ledger, developers can create applications that handle:
- Multi-modal journey planning
- Automated reservations
- Seamless payments across different service providers
This interoperability is crucial for building user-centric mobility solutions that reduce congestion, lower emissions, and improve urban livability.
Johann Jungwirth, former Chief Digital Officer at Volkswagen, underscored the strategic importance of this collaboration when he joined the IOTA Foundation’s Supervisory Board in January. He stated that IOTA’s platform enables connected devices to exchange value in the form of micropayments, calling it “ideal for the future of IoT.”
The absence of transaction fees is a key differentiator. In environments where machines conduct thousands of tiny transactions daily—such as paying per kilowatt-hour or per kilometer driven—a fee-based model would be economically unviable. IOTA’s feeless architecture removes this barrier, making it a strong candidate for widespread adoption in machine economies.
Industry-Wide Collaboration Through MOBI
The momentum behind IOTA doesn’t stop with Volkswagen. Earlier this year, IOTA joined forces with major players including BMW, General Motors, Ford, Renault, Bosch, Hyperledger, and IBM to launch the Mobility Open Blockchain Initiative (MOBI)—a global consortium dedicated to advancing blockchain and distributed ledger technologies in the transportation sector.
MOBI’s mission is to create open standards that accelerate the development of smart mobility solutions. By fostering collaboration across automakers, tech firms, startups, and governments, the initiative seeks to avoid fragmentation and ensure interoperability across future transportation networks.
IOTA’s participation highlights its growing influence in shaping the technological foundations of tomorrow’s mobility landscape.

Frequently Asked Questions (FAQ)
Q: What is Tangle, and how does it differ from blockchain?
A: Tangle is a distributed ledger technology based on a Directed Acyclic Graph (DAG), not blocks or chains. It eliminates miners and transaction fees by requiring each new transaction to validate two previous ones. This makes it highly scalable and ideal for IoT applications like connected cars.
Q: Why is feeless transaction capability important for connected vehicles?
A: Connected and autonomous vehicles will perform countless micro-interactions—like paying for parking or charging. Charging even a small fee per transaction would make these interactions impractical. IOTA’s feeless model enables frictionless machine-to-machine economies.
Q: Can IOTA be used beyond automotive applications?
A: Absolutely. While automotive use cases are prominent, IOTA’s technology applies broadly across IoT domains—including smart cities, energy grids, supply chains, and industrial automation—anywhere secure device communication and microtransactions are needed.
Q: Is Volkswagen planning to adopt IOTA commercially?
A: While no official commercial rollout has been announced yet, the successful PoC indicates strong interest. Volkswagen continues to explore integration paths within its digital strategy and MaaS initiatives.
Q: What role does MOBI play in advancing blockchain in transportation?
A: MOBI brings together leading automakers and tech companies to develop open standards for blockchain use in mobility. Its goal is to ensure compatibility across platforms and accelerate innovation in areas like autonomous driving, shared mobility, and vehicle identity management.
Q: How does IOTA ensure data security in vehicle communications?
A: IOTA uses cryptographic signatures to authenticate all transactions and data transfers. Its decentralized nature prevents single points of failure, while the immutable ledger ensures tamper-proof records of software updates and vehicle activity.
The partnership between IOTA and Volkswagen at CEBIT '18 marks a pivotal moment in the evolution of smart transportation. By combining automotive engineering excellence with innovative distributed ledger technology, they are laying the foundation for a safer, more efficient, and fully connected mobility future.
