As far as I can tell, "Web3" is a meaningless, nebulous buzzword used by the crypto community to pump their assets. You will have to tell us what you think it means.<p>Decentralized, cryptographically-verified data exchange on the web has existed for decades. If you want to learn about applications for it, read about BitTorrent, HTTP over TLS (which you used to access this website), LetsEncrypt, Mastodon, and IRC.<p>The part of Twitter discussing "Web3" and crypto is, at best, a deep well of gullible people who don't know anything about the existing web. At worst, it's a bottomless ocean of fake accounts, shills, and VC nonsense. I would be very surprised if you could learn anything useful there.
