There is this CIP:
- CIP-0050? by @Michael.Liesenfelt, which fairly well articulates the problems caused by the minPoolCost amongst other things.
There has also been innumerable discussions on this forum including this one by @Colin_Edwards who was working for IOG as a “quant”.
There is also this awesome analysis paper by @MahmoudNimer (adalink.io) which analyses the effect of the reward sharing formula construction: https://github.com/cardano-foundation/CIPs/files/9389814/Stakepool.Pledge.Influence.in.Stake.Rewards.Distribution.pdf
That analysis paper is quite interesting because it really breaks the formula down and leaves you wondering why the reward sharing formula was constructed as it is today.
But with all that said, I still can’t get past the fact that the 340 Ada number was simply plucked from the air at a time when the USD price of Ada was much lower, and now the community has voted to halve it.
