Plebbit is a selfhosted, opensource, nonprofit social media protocol, this project was created due to wanting to give control of communication and data back to the people.
Plebbit only hosts text. Images from google and other sites can be linked/embedded in posts. This fixes the issue of hosting any nefarious content.
ENS domain are used to name communities.
Plebbit currently offers different UIs. Old reddit and new reddit, 4chanw, andhave a Blog. Plebbit intend to have an app, internet archive, wiki and twitter and Lemmy. Choice is important. The backend/communities are shared across clients.
There are other alternatives to DNS that don't require you to boil the oceans, e.g. GNUnet has their own thing.
This isn't decentralising the whitelist/default subs, it's shareholder-ising. It's also just recreating the notion of admins in ActivityPub, or replay controllers in notstr. You still have a set of privileged users able to make decisions for others, albeit less privileged than AP admins.
I'm not saying nor do I believe crypto is the future, but this project seems to use Etherium and Solana, both of which are proof of stake and will not be using huge amounts of power.
Etherium actually transitioned to proof-of-stake? Last I heard it was something they were planning to but it was being delayed for years. Good for them for actually doing it, I still don't trust the technology and refuse to use anything that integrates it, but at least it's not so actively destructive.
