Not based on compute so much as who holds the coins. If you have 32 eth (I think that's the number) you can act as one of the few "validators" that run the blockchain. In exchange, you are rewarded, but for your "staked" eth quantity rather than compute power. Thus there is no real incentive to overpower your node beyond just a server and cpu. There is incentive to "stake" more coins (which are then frozen).
Eth staking pools already exist for the 99% with less than 32 eth. They are potential points for scams of course, but so were mining pools really.
That's the basics, as I understand them.
