Minted CCD to finalizers The share of new CCD paid for finalizing blocks.: None
Fees to validators The share of transaction fees paid to the validators that made the blocks.: 45%
Fees to the GAS account The share of transaction fees kept in the GAS account, which pays validators a little for each block over time.: 45%
