Many of the trends and ideas that shape America come to California first, so it’s worth noting that the state has introduced a big tech upgrade at its Department of Motor Vehicles. As Fortune was first to report, the agency is in the final stages of replicating its title database on the Tezos blockchain and expects to launch consumer-facing applications tied to the blockchain within three months.

In practice, this means California drivers will soon be able to hold their car titles as NFTs in their digital wallets and the DMV will be streamlining the cumbersome process of title transfers. Based on comments from the agency’s chief digital officer and from the software firm overseeing the project, the initiative sounds serious—and potentially transformative.

If millions of Californians start relying on blockchain to track ownership of their cars, other states will soon follow suit, and the crypto industry will finally be able to point to a major real-life use case for the technology. If this transpires, it’s not hard to see other agencies and institutions—think land title offices and university transcript departments—likewise adopting blockchain.

Most significant of all, California’s DMV project could lead to a breakthrough in the field of digital identity. For a decade now, crypto boosters have hailed blockchain as a way to stop relying on data-gobbling companies like Google and Facebook to log in to websites—and instead rely on the privacy protections offered by blockchain to enjoy a “sovereign” identity on the web. Until now, the “sovereign identity” dream has been pie-in-the-sky since, at the end of the day, it is the state and not some crypto startup that has ultimate authority on confirming you are who you claim to be. If California decides to expand the DMV blockchain program, it could mean that it will be possible to rely on tools like zero knowledge proofs to prove things like your age or identity without disclosing a raft of other personal details.

Yes, there’s no guarantee this will come to pass and the California DMV project could fizzle, especially as states have previously announced blockchain projects that amounted to little. Vermont, for instance, announced it would put land titles on the blockchain in 2018 and this has so far appeared to make little difference to the lives of homeowners there or anywhere else.

Still, this time feels different. Blockchain technology has evolved and California has a history of introducing major innovations for its massive population that spread to the rest of the world. If it pulls this off, many of us could be carrying NFTs of our driver’s licenses in 5 years.
