But is that a plausible scenario? Certainly *if* the concensus rules required a 99% supermajority of miners for the hard fork to go ahead, then there would be absoltely no rational reason for merchants and users to refuse to upgrade, even if they don't support the changes introduces by the hard fork. Their only choice, if the fork succeeds, is between the active chain and the one that is effectively stalled - and, of course, they can make that choice ahead of time. roy
