Delegation Analysis for Epoch 220

In this week’s delegation analysis video, we included a new plot of the lifetime ROS for every pool versus the total stake and explain what it means. Please check it out here!

Epoch 220 (27 September to 2 October 2020) network parameters:

k d Total stake Registered pools
150 0.640 15.86B ₳ 1091

The stake snapshot for epoch 220 occurred on 9/22/2020. The total staked ADA increased by 0.65% since the last epoch, up to 49.96%. We saw a sharp decrease in the number of active pools this epoch - down 75 pools to 1091. The minimum stake required in order to expect to make a block decreased slightly to 2.04M ₳, leaving 69% of pools below this threshold. The number of pools falling into the 0-slot bin decreased by 76 pools this epoch.


757 / 1109 pools fall into the 0-slot bin


This plot omits the pools in the 0-slot bin


Here is the plot of lifetime ROS vs pool size. Please see our video above for a discussion of the meaning behind it.

For more information about the concepts and math behind this and past analyses (e.g. the meaning of k and d), as well as the full table that this chart was generated from, see our full post here.
