Hey. I'm not sure if this is true but apparently Ethereum might use something called DPOS (1). I haven't read the paper yet (2) but according to (1) vitalik agrees that proof of work is dead.
I believe this needs serious analysis in case they are right and onto something.
SlipperySlope and anyone else who has an interest in PoS:
What are you opinions on this DPoS? Is this the holy grail that people have been waiting for? I thought Vitalik was a PoW hardliner. So I was a bit surprised to read this.
