- Farcaster [https://farcaster.xyz/] is another one, that takes a more hybrid approach of using Ethereum for trustless identity, but stores social stuff in a "sufficiently decentralized" way.
- Radicle [https://radicle.xyz/] is a decentralized Github basically, that (optionally) uses Ethereum to store the Git HEAD of a "project" essentially.
- Arweave [https://www.arweave.org/] stores files permanently using a cool "endowment" mechanism. Currently, the network has secured its storage for like 1000 years in theory.

- ENS [https://ens.domains/] is a universal username system.
- Unlock Protocol [https://unlock-protocol.com/] uses NFTs for tradeable subscriptions, event tickets, etc.
