Would likely require a form of NFT that's a little different and probably more complex than the current forn. Something about having the car key also be a cryptographic key, and transfers of the NFT invalidating keys or requiring rotation.

What is it with NFTs and solving theoretical problems in extremely complex ways. Car thefts at at 1/3 of what they were in the 90s, and the existing mechanisms for buying/selling cars work just fine. Why do we need to introduce car DRM with brittle, distributed access control systems? You're more likely to get your tires or cat stolen - no NFT is going to prevent that.

You could shape the NFT in the form of a metal rod with notches on it. When placed inside a slot and turned, the car could validate that the right pattern of notches exist on the NFT and turn on. If you want to sell the car, simply hand off the physical NFT to the new owner.

  Well crypto allows for trustless digital transfers. Like selling a house halfway across the world, without having to fly over to hand off the keys.

    So the person halfway around the world can immediately start enjoying their house?

      I assume it would be something like, the door lock is tied to the current owner as defined by the blockchain. No need for intermediaries, and no physical key.

        So we're back to the original question: without an Internet connection, this blockchain-controlled door won't open, even if you're the legitimate owner. Or if it does open without Internet, then you can buy the house NFT, but the seller disabled the Internet connection in the house so the door doesn't know about the transaction. Now you're locked out even though you theoretically own the house on the blockchain. Turns out the blockchain doesn't solve ownership of physical objects. You still need intermediaries like the police and courts to decide who owns the house.

        Or perhaps it's looking towards a future where internet access is more reliable, as it has been getting for the past few decades

        Do you really want to be locked out of your house or car if the Internet is down? We've had the electrical power grid for over a century, but power cuts and brownouts are still a thing. Designing vital systems to assume 100% reliability of shared systems is dangerous.
        kareemsabri 4y ago
        I agree. It's not only that it's dangerous (let's say the internet always worked, someone could still ship a bug to the protocol, or too many nodes could fail, or it could get hacked), it's just not even better. Technologists often seem to not start with problems. What is the problem being solved by a blockchain based lock? What pain point exists that would no longer exist? Having to carry keys? Keys are already decentralized and fully controlled by me. I can copy it and distribute it freely. Putting an intermediary (a blockchain) between myself and access to my house just seems silly.

    Yes. But real estate law does not.
