If you are curious to know how root stakers (validators stakers) will earn after dTAO launch, then this the answer:

Root stakers earn by receiving a portion of alpha emissions from all subnets, which is automatically converted back into $TAO through the root subnet (NetUID 0).

Breakdown of Earnings:
1.$TAO Weight Contribution
•A fraction (0.18 or 18%) of the $TAO staked on root is counted as stake in each subnet.
•This increases their share of subnet rewards.
2.Subnet Token Dividends → $TAO
•Subnets emit ALPHA tokens to validators and stakers.
•The root share of ALPHA emissions is automatically sold for $TAO using the subnet pool.
3.Root Stakers Get $TAO Back
•The converted $TAO is distributed back to root stakers in proportion to their stake.

Effect:
•Root stakers benefit from all subnet emissions.
•Their earnings increase if subnet token prices rise, and they face sell pressure when prices drop.
