MFW I see someone advocating for a soft fork to create federations run by miners instead of just creating their own federation without a soft fork. 
Discussion
We trust miners for layer 1 transactions already. It’s only logical to trust them for layer 2 transactions.
Proof of work over custodianship any day for me.
Couple of things:
1. I trust economic incentives, not miners. The inherent uncertainty around changing those economic incentives is in large part the root of my dislike for this proposal.
2. Drivechains are still custodianship, just from an indefinite and dispersed group. You haven’t solved the peg out issue by tossing it to miners and please don’t pretend you have. Also if I’m going to have to trust a custodian I’d rather know specifically who they are rather than just “the miners”.
I recognize the need for scaling solutions, but this one ain’t it.
Whole point of blind merge mining is that it’s trusting economic incentives. Bitcoin Miners care about maximising profits and the longevity of the bitcoin network more than any other entity in the bitcoin community. If they don’t they get out competes by more efficient miners.
