A community dedicated to fediverse news and discussion.
Fediverse is a portmanteau of "federation" and "universe".
Getting started on Fediverse;
I think people often forget federation is not a new thing, it's a first design for internet communication services. Email, which is predating the Internet, is also federated network and most popular widely adopted of them all modes of Internet communication. It also had spam issues and there where many solutions for that case.
The one I liked the most was hashcash, since it requires not trust. It's the first proof-of-work system and it was an inspiration to blockchains.
I don't know what the answer is, but I hope it is something more environmentally friendly than burning cash on electricity. I wonder if there could be some way to prove time spent but not CPU.
