Yoroi shows data from adapools.org
The Blocks shown is actually Blocks in current Epoch I believe (hover over the question mark for more details). So that would be 0… I agree that it’s a shame that’s the only thing that shows.
The cost as ADA4Good already mentions is a calculated metric. I too don’t know exactly how that’s calculated (I’m sure it’s explained somewhere on adapools.org or you can contact them for further details) but I do know it attempts to calculate actual costs seen for delegates… This is in line with what ADA4Good said previously… When you consider actual cost, you have to also consider how the 340 fixed fees affect delegates.
It’s a shame the fixed fees have to be that way because all I can see is that this hurts small pools and is a check-and-egg problem. You need more stake to have the effect of the 340 minimum fee distribute nicely where it’s negligible, but you can’t get stake because people generally don’t want to lose rewards because of the 340 min fee.
A possibly better design to that min fee in my opinion would be to introduce it incrementally. So here’s an example:
At an estimated 1 block per epoch - 10% of fixed fee (so technically pool only gets 34 instead of 340 fixed fee)
At an estimated 2 blocks per epoch - 20% of fixed fee
At 10 blocks+ per epoch - Full fee in effect.
This sort of design in my opinion significantly helps small pool operators since their costs end up being comparable to larger pools.
Another thing that would’ve helped a bit I guess is the effect of a0 on rewards. That helps curb the MYPOOL1, MYPOOL2, MYPOOL3… MYPOOL16 sc scenario we’re in today.
Hope this helps.
