Moxie's first impressions of Web3

What a great post by Moxie Marlinspike.

Instead of storing the data on-chain, NFTs instead contain a URL that points to the data. What surprised me about the standards was that there’s no hash commitment for the data located at the URL. Looking at many of the NFTs on popular marketplaces being sold for tens, hundreds, or millions of dollars, that URL often just points to some VPS running Apache somewhere. Anyone with access to that machine, anyone who buys that domain name in the future, or anyone who compromises that machine can change the image, title, description, etc for the NFT to whatever they’d like at any time (regardless of whether or not they “own” the token). There’s nothing in the NFT spec that tells you what the image “should” be, or even allows you to confirm whether something is the “correct” image.

I'll happily live out my life in web1, thank you. You kids have fun, though!
