However, I would like to easily see a non-political db where you can easily track the paper graph to figure out which papers are based on discredited research and/or researchers taking money from special interest groups.
* or if not "free", a very small marginal cost, in terms of say data aggregation and programming effort
which is all to say, like so many of the things people want to use a block chain for, the hard part is the politics and the real-world nuance, not the immutable ledger. the immutable ledger is not trivial. but compared to the other stuff, it's not all that hard (and is certainly more solved, at this point).
I hope this publication gets an implementation soon.
Similar issues occur for review articles, which are about analyzing data already present rather than analyzing new data. Moreover, this would also hurt actual replications. It kind of seems like being the last to replicate something would be without compensation.
In all seriousness, I have always thought that Blockchain could pose a good solution for the issue of peer-reviewing scientific papers. It provides a descentralized infrastructure with "tokens" that can be transferred to provide "prestige" to papers and authors.
