Autonomous vehicles (AVs) are an emerging technology that is being explored in a number of industries.

Blockchain can be used to facilitate the operation of AVs by providing a decentralized, secure, and transparent platform for exchanging data and transactions.

For example, a blockchain-based system could allow AVs to communicate with each other and share data on traffic conditions, road hazards, and other relevant information.

Additionally, smart contracts could be used to automate payments for services such as tolls, parking, and ride-sharing.

Finally, blockchain could be used to create a tamper-proof record of AV operations and maintenance, ensuring the safety.
