Technology rarely advances for reasons that benefit the majority. It advances to make a few people rich, kill people very efficiently, or to increase profit margins on porn sales (see item 1, I guess).
If you think about the really good applications of things like crypto, NFTs, blockchain, etc., you quickly realize that they are things that aren't marketable or profitable for the entities that would need to implement them. If all the banks and credit companies bought into something like blockchain or NFTs, then transaction fraud and identity theft would disappear overnight... but what would THEY get out of it? The only way it's ever going to happen is with coordinated government mandates, and nobody running for office has the faintest idea of what crypto tech is other than "dumb way for the nouveau riche to waste their money"
How does crypto stop identity theft or transaction fraud? Crypto does nothing for credit, which is basically what identity theft is, and if you're missing how widely there's transaction fraud on crypto you haven't been paying attention.
It's not the cryptocurrency itself that prevents fraud, it's the surrounding technologies such as blockchains and NFTs.
Using NFT to own the address to a PNG is hilariously stupid and worthless, but what it's actually great for is receipts. If I buy a donut and get an NFT proving that I now own the donut (along with metadata about where and when I purchased the donut) and months later I am on trial for murder, I can prove to the court with absolute mathematical certainty that I couldn't have killed anyone at that time because I was eating a donut halfway across town.
Using blockchain similarly is great for proving your transaction history. Maybe I somehow faked that NFT about the donut? Well, I couldn't have, because it was months ago and blockchain history is cryptographically impossible to spoof.
These are obviously contrived examples, but when applied at scale it becomes an extremely powerful way to verify truth. Yes, I did in fact buy those tickets, here's my NFT, now let me on the plane. No, I did not spend $3000 on knock-off accessories, here is my blockchain. The odds of someone being able to fake these is extremely low.
But, again, this will never come into practice, at least not in the near future. As @beefcat pointed out, implementing these systems would be expensive for the established financial institutions, and would present new challenges for them to create new processes for handling. An awful lot of work to create something that is stronger and safer when there is little motivation for them to do so.
@dreadgoat@kbin.social @beefcat@beehaw.org there's a whole insurance industry for covering legal fees regarding improperly titled real estate and it generated over $20 BILLION dollars in premiums in 2022!
If the title to a house were an #NFT, you could verify it's validity in seconds!
I don't see why a distributed blockchain is actually necessary to solve this problem though. Basic public-key cryptography is enough to sign and validate documents like real estate titles, without all the overhead incurred by NFTs. Our problem is that we aren't even making effective use of technology we've already had for decades to solve this.
