Excluding an approach for transparency, there is nothing "new"
I guess transparency is one of the fundamental things, players look before deciding where to deposit their money. You are right this is not innovation or something but considering the range of provably fair games at Stake it is still miles ahead of any other online casino.
With transparent casinos you have a slim chance of winning, with rigged ones it is zero.
Well said. Sometime there is 'bait and switch' also in rigged slots

(at least that is the widespread belief).
