Gregory's Server@Torfinn @EposVox Researchers don't go to these publishers because they can't put their PDFs on a website. They go to these publishers because their publications are considered prestigious, and publishing at prestigious journals is effectively required to advance your career.
The peer review processes are also independent from the publishers, they are organized and done by other researchers.
The problem is social not technological.

If universities stopped caring about the prestige of publication when making hiring/promotion decisions, researchers could cut the publishers out of the equation tomorrow. No block chain necessary, they already have the organizations and tools they need.
