Anyone can technically start their own journal as well. The only thing that has to happen is for the journal to gain the trust of the scientific community over time (which, again, is mostly decentralized). Anyone can build a university. All it has to do is to build trust.
No coin or website will make that more decentralized.
> This specification describes SciFed, a standard for federation of scientific activities and content using ActivityPub. It is intended to be used in the context of the Activity Vocabulary and provides a vocabulary for activity types needed in the context of scientific exchanges.
It is from 2019, and probably from the OLKi project: https://framagit.org/synalp/olki/olki
Don't know if it is still active, but the idea to use the Fediverse for Open Science interop is appealing.
There're several incentives to make your research as obscure and unreproducible as possible. First, you want to keep most of the details private to your lab. Why would you help other labs? So that they can make a discovery before you? No way!
Next, suppose it was easy to re-run your whole data analysis pipeline outside your lab. So there's someone you don't even know who tries it, and finds and tiny bug in your code that invalidates your results. Now you have to publish a correction, or even retract. You don't want that happening ever. So you publish some undocumented and unrunnable code so that nobody would even bother reproducing.
