TL:DR (at $7/ATOM and 10% max inflation, 5% commission, 67% bonded, and ~$600/mo to run a validator per chain):
Validators 1-89: Profitable or break-even if this went through running 2 consumer chains
Validators 90-115 would break-even or run at a slight loss since they cant soft opt-out with 2 consumer chains currently active
Validators 116-160: Can soft opt-out and are profitable running just the Hub
Validators 161-180: Unprofitable today and would be slightly more unprofitable if this went through
I am in favor of this. The Cosmos Hub is overpaying for security relative to its peers and it is ALSO distributing this security budget poorly where top validators are making out handsomely while some validators in the lowest quartile of the active set are running at a loss at current ATOM prices (but not all).
With the recent increase in minimum commission to 5% and a drop down to 10% max inflation at 67% bonded, all validators with >150k ATOM delegated to them (160 out of the 180 validators in the active set) would STILL be running at a profit at current ATOM prices if they have opted out of running the consumer chains (any validator with less than 288k ATOM delegated, aka bottom 5% of VP, can opt out).
The validators right on the border of the soft-opt out (in the top 95% VP) that cannot opt-out of running consumer chains are the ones in the worst position, but would STILL be break-even with running 1 consumer chain but would be currently running at a loss of ~$7k/yr. We are in peak bear market conditions, and in my opinion, guaranteed profitability should not be expected by everyone (stakers, validators, etc).
This is also assuming validators don’t own any ATOM personally (which is likely not the case).
The right path is to lower inflation AND introduce a Vote Power tax that aligns validators and also can generate a baseline of earnings for all validators. Please see my post here that outlines how this VP Tax would work, if implemented.
In conclusion:
- Hub is overpaying for security
- Hub is distributing this inflation poorly due to poor distribution of staker
- Overwhelming majority of validators would still be PROFITABLE or BREAK-EVEN with this decrease in max inflation when you consider the soft opt-out and the new min commission
- Lower inflation and implement VP Tax
