Currently power decides 3 important things : rewards / consensus participation / voting rights
So we can say that there are at least 3 important axis of decentralization.
From experience and history, it is not very practical to try economic(rewards) decentralization in crypto-ecosystem. But, it does not mean we have to give up consensus decentralization.
Therefore, I suggest to use different metric when we calculate consensus. For example, we use log(power) for consensus summation. If we adjust this feature, we will have much better decentralization on the axis of blockchain consensus. It improves liveness, censorship risk, manipulation risk, etc.
If big validators get the same rewards and same voting power for governance, why they want to get more “consensus power”? I think there is no economic incentive on this. Therefore big validators will not bother themselves splitting their validators to gain more consensus power.
Please share thoughts and better ideas!
Below is the expected result of consensus power distribution changes when we use log(power) for consensus power share percentage.
