The marketing behind Cardano and Ouroboros is that it is the first “peer reviewed”, “provably secure” proof of stake consensus algorithm. Upon reading their paper it becomes clear to those familiar with BitShares 1.0, Graphene, Steem, and EOS that Ouroboros is a copy of Delegated Proof of Stake (DPoS) with a few counter-productive modifications.
Yeah, that really stuck in my craw while reading the whitepaper, and I immediately called bullshit!
Thanks for writing this @dan.
