I've used IPFS[1] to store and host files completely separate from cryptocurrency. IPFS is a major backbone of Web3 tech, and is responsible for enabling much of the current NFT craze because IPFS is free. The same company that made and maintains IPFS also created Filecoin, and the fact that the two are completely separate projects to the point where I can and have used IPFS for free without having any knowledge of or owning any Filecoin speaks volumes. Judging from some view of the Web3[2] stack, I can create a decentralized application that exists entirely through p2p storage without ever actually having to incorporate a blockchain or cryptocurrency, and this can still be considered Web3 technology.
