"double-dare"... heh, sounds like the playground all over again.

I think what you are saying is "put up or shut up" or, show your investment in BIP148 by capital investment in hashing. I kind of agree... what good is BIP148 without some significant hashpower behind it?

In the same spirit, can we ask something of the big blockers who think Core code is so bad? Why do most big blocker projects first fork Core code then? Why not put up or shut up, and write your own superior implementation from scratch?

(For the record I am pro-SegWit and also in favor of a modest base block size increase... with more to come later, not a huge jump to 8MB or 20MB out of the gate. I want both on-chain and off-chain scaling. I'm just disgusted with how nasty this whole debate has become on both sides.)
