@kushti I think you might have misunderstood how the consensus protocol works in Bitcoin. It's not the longest chain, but the one with the most work put into it that is accepted.

@sktrdie Can you please send me link to a spec / source piece proving that?

@kushti sure: http://bitcoin.stackexchange.com/questions/936/how-does-a-client-decide-which-is-the-longest-block-chain-if-there-is-a-fork http://bitcoin.stackexchange.com/questions/936/how-does-a-cl... http://bitcoin.stackexchange.com/questions/29742/strongest-vs-longest-chain-and-orphaned-blocks http://bitcoin.stackexchange.com/questions/29742/strongest-v... Pieter Wuille is a core developer afaik: "The actual rule always favors the chains which required the most "work"."

  @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).
