What pools will those be?  I've gone through the Discord and it's never said.  Someone even asked what other pools besides supernova and it was not answered.  I've heard through the rumor mill that supernova was promised to be the only pool at launch.  If that's the case, be upfront and let everyone know you support a centralized network, otherwise release the code so other pools can join in at launch.

50% is still too high for the dev fund (call it what you will, it's funding development).

A promised single pool launch (100% of the hash on a single pool...no bueno) and 50% of the rewards to "fund" the dev team seems like a disaster coin waiting to happen.  Miners need a reason to mine and 25% of the reward, with the current prices, isn't very motivating.  There's many very successful projects that run just fine without a 50% dev fee.  There's also many that fail with a much higher dev fee.  A high dev fund doesn't substitute for a properly ran project.
