Re: BIP 110 post mortem. Miners don't control Bitcoin, and pools don't control miners. Pools are payout coordinators for thousands of individual operators who can repoint hashrate elsewhere in ten minutes. A pool signaling against its miners' interests just loses the hashrate. Miners exchange hashrate for block rewards, then sell BTC to pay energy bills in fiat. If there's minimal economic support behind a fork, the rewards can't be monetized and mining it is burning money. Hashrate follows the buyside, because that's how they stay in business. That's what "economic nodes" means.(Dylan LeClair)
