Some interesting Twitter threads regarding the minPoolCost discussion:

We have, in fact, discussed that paper a while back here in the forum:
No, it does not discuss or even prove a minimal pool cost, minimal fixed fee to be necessary. It just assumes that pools do declare an honest pool cost, fixed fee. And goes on to prove something else: That a saturation is necessary.

Interesting take from the “We have to prevent race to the bottom.” angle. Probably true that most delegators are not very rational and do not at all behave like the game theory models want them to.

And a thread arguing that it is actually a feature that small pools are not attractive to prevent attackers from starting thousands of attractive small pools.
