I've always wondered if some sort of decentralized, community-led system would be better than the current peer review process.

That is, someone can submit their paper and it's publicly available for all to read, then people with expertise in fields relevant to that paper could review and rate its quality.

Now that I think about it it's conceptually similar to Twitter's community notes, where anyone with enough reputation can write a note and if others rate it as helpful it's shown to everyone. Though unlike Twitter there would obviously need to be some kind of vetting process so that it's not just random people submitting and rating papers.
