As the FAQ says, the base protocol doesn't use tokens. Meaning, there are no critical features tied to any blockchain.
The crypto features we implemented in our clients are not required by the protocol. The protocol works perfectly fine without them. We implemented them in our clients because they are nice, and they are:
- readable names using crypto names, instead of having to see long alphanumeric IPNS public keys as addresses
- NFT profile pics tied to a user's plebbit account, because we whitelist the specific NFT collections to prevent NSFW profile pics
- tipping, which is an upcoming feature, to provide a fully decentralized alternative to Reddit awards/gold (plebbit users will actually make money, so will the community owners and admins since they'll be able to tax tips in their community; and there's no corporation/global admin that gets a cut)
https://seedit.app is a fully decentralized client for the Plebbit protocol, using a old.reddit UI.
You can also try a demo of a much faster version of Seedit, it works via public RPC: https://plebbit.mooo.com/seedit/#/hot (warning: you're using someone else's full node to browse fully P2P, so if you create a community it's in their node, it's not yours). This version showcases how you can create a community even on mobile device, running a full node remotely. But we have to build user auth for this, it's in our roadmap.
