Ok, I was wrong, about 1%, so what? 12% is still a lot of when people don't want to give 1-2.5% for dev fee for miners or 1% for mining pool.
And as we count we see = 100% mining - 12% dev coin/nodes/dao - 2-2.5% dev fee miner - 1% pool = 84.5-85% of your mined coins.
And then taxes after sale the currency, so when we can only have about 70-72% of our mined coins... Everybody wants to be in the middle of our (miners) coins. 3.5% there, 5% out there, but miners mainly give you the strength of your network, I feel like taxation, so I will always choose the solution without taxation, or without fees. Just give me the address for donation - I will donate for your work, and not that you will have my earned coins. Zen is nothing more than another reincarnation of ZCash, just a little more powdered to look more 'open', with lower fees than ZCash. Nodes will always be in some part of centralized - it's not an obvious central solution, but it's similar to check pointing - it's based on more centralized solution.
