> OpenSea is probably the biggest thing, it's the largest NFT marketplace and it uses web3 extensively. Is this website hosted or somehow powered by web3? Does it store its data in a blockchain or a traditional MySQL/postgres/etc db? Are its user accounts nothing but wallet addresses and entirely managed and controlled by the wallet owners? Is the computation, access control etc done using smart contracts and resilient to dropping their servers? These are honest questions I really don't know the answer to, but based on other posts in this thread this would all be required to qualify as a proper web3 example.

Powered for sure, but I don't know if absolutely everything is stored via web3, like their html or whatever. I know the NFTs and metadata are[1]. Purchases, transfers, bids, offers, etc. are handled using smart contracts. User accounts are just wallet addresses, yes. I don't know how it manages access control, but besides what I assume is some sort of admin access it doesn't really need it. If OpenSea doesn't qualify as web3, I don't know what would.
