Unfortunately there are still few miners in pools. The pool on the site is almost inactive.
As far as I understand the reward for the block currently paid by pool is 1.125 TCR.
This is only 1% of the block 112.5 TCR. The remaining 99% goes to devs?
No, for devs always is 10%, for PoW now is 1% in January 2020 will be changed to 5% up to 20%, MN are from 15% to 25% and Science wallet and Crypto Interest wallet.
Science wallet is for commercialization of new science technology in the future, we don't use this coins, as you can see on explorer, and crypto-interest is for mobile apps to make dividenet for freezing coins, something similar to PoS, but this is not PoS.
