10% of the block reward goes directly to the Dash general treasury. This equals $10,000+ per day. Another 45% goes to large holders of Dash called masternodes who provide a mixing service representing about 2% of the total transactions on the network.
45% goes to the masternodes and another 10% to the general treasury, of which distribution is voted on by the masternodes, so totaling 55%. How is this not centralization?
