You’re correct there is no guarantee of if/when Mento will sell. My main point here being that, according to the passed governance proposal, CELO is not in their target collateral, meaning if/when collateral becomes tight due to additional issuance or adverse foreign exchange movements, CELO seems first on the chopping board unless I’m mis-reading this approved governance proposal.
Also, the epoch rewards doc you quoted earlier was superseded by the “Great Celo Halvening” proposal; have you factored it into your arguments?
Yes, I’ve considered the Great Celo Halvening before my comments above.
Nevertheless, I still believe post L2 transition, we simply don’t need 100+ validators. I can imagine something like 50-60 with max validators per group going slightly down to 4 to still promote having at least 20-30 independent groups, which seems sufficient to me. It doesn’t have to be 55, but I believe a reduction in the number of validators to 50-60 would not materially undermine the network security.
