The updated model can be found here
As we did before, we consider basic 4 scenarios for current and future state of BC:
#Scenario 1: max risk offline (single big operator, 100% validators offline for 7 days)
#Scenario 2: min risk slashings (300 validators slashed)
#Scenario 3: medium risk slashings (single big operator, 30% validators slashed, 100% validators offline for 7 days)
#Scenario 4: max risk slashings (single big operator, 100% validators slashed)
The updated model includes Bellatrix spec that provides harsher penalties.
In the first three scenarios, the impact varies from 177 to 5,132 ETH and they can be covered with the proposed 5500 stETH.
The last scenario (tail one) requires alternative options that in my opinion should be related with proactive risk management like validator diversity management, risk and response planning, etc. rather than insurance.
