RE: Reponse to Vitalik's Written Remarks
Your review of Casper is 2yrs old and is from when Ethereum has just launched... That is just too stale to be taken seriously in this space, especially given how much Casper has moved around since then. Worth refreshing or not citing.
In my Review of Casper, Ethereum's proposed Proof of Stake Algorithm I throughly debunk the algorithm.
And if you thoroughly debunk it, you (and other critics) have to consider why so many devs take Casper seriously enough to work on Ethereum as a platform for their projects. Otherwise it's like Greg Maxwell claiming to have proven that Bitcoin he proved Bitcoin was impossible...
