Darknode operator must lose profit for 2 epochs even if the darknode is serving the network for a year or more.
Assuming the monthly income is fixed at $1,000 per epoch:
If 100k REN locked for 6 epochs the total profit will be $4000 instead of $6,000 (-33.33%)
If 100k REN locked for 12 epochs the total profit will be $10,000 instead of $12,000 (-16.66%)
If 100k REN locked for 24 epochs the total profit will be $22,000 instead of $24,000 (-8.33%)
Not considering the increases in the network income in the long term.
What is the reason to enforce REN holder to pay penalty after serving the network for while?
How this could incentivize more DN registrations?
As long as the bonded REN is locked, the profit should be counted (my opinion).
