> I have a partial solution: researchers “publish” papers to arXiv or similar, then “submit” them to the journal, which conducts peer review. The “journal” is a list of links to papers that it has accepted or verified.
This made me curious about how arxiv operates. It seems that you require endorsement to become a registered author, and the submissions are moderated[1][2].
This already seems sufficient to keep out spam and clearly junk science. What is the value add of official(?) journals?
