Good morning :)
This referenda seeks to increase the minimum commission from 3.0% to 8.5% and keeps all other staking configurations unchanged. It is being proposed to foster a sustainable environment for all validators in light of reduced on chain returns as well as present market conditions.
Appreciating that there was no forward discussion I anticipate there will be emphatic responses. To aid with your decision making I've also included some supporting data for your consideration.
Effects on validator earnings
A validator operating at 3% commission can stand to earn (485.2/1000)* 4 * 30 * 0.03 = 1.75 KSM/month, this equates to ~70 USD/mth.
The proposed configuration allows validators to earn (485.2/1000)* 4 * 30 * 0.085 = 4.94 KSM/mth which equates to ~ 200 USD/mth
Effects on nominators
Assuming a total stake of 6600 KSM, at 3% commission a nominator earns ~10.42% APY whereas at 8.5% commission a nominator* would earn ~9.83% APY, a 0.59% difference.
Validator commission distribution
Three hundred and eight (308) potential validators would be affected by the change to varying degrees.
