@sktrdie Thanks for the links! Ok it seems at the moment Bitcoin uses some kind of a cumulative difficulty. P.S. Joining a network is implemented in the same way usually for both PoW/PoS currencies.

  By the way, if you're aware of any peer-reviewed papers out there that explain how PoS works, I'd be interested in reading them. Academia has been quite shy on the subject.

    Unfortunately, I dont' know any peer-reviewed proof of PoS (im)-possibility, threat model etc. Time is needed here probably, we got good formal framework of PoW only in 2014, 5 years after Nakamotos' WP(I mean Backbone's paper https://eprint.iacr.org/2014/765.pdf https://eprint.iacr.org/2014/765.pdf).
