Given that the threshold is lower than is normal for hard-forks, noise on the measurement could cause an activation even if less than 75% of miners agree. It also means that the vote has to be sustained for longer and inherently gives a longer notice period. Two weeks seems low for an upgrade warning. I guess there would be an alert on the network. Do old nodes detect an upgrade by version numbers? If that was headers only, then they could detect that large blocks have activated. Have you considered a "fail" condition? For example, if 750 of the last 1000 blocks set bits 4 and 14, then it counts as a rejection by 75% of the miners. Alternatively, if the rule doesn't activate by 11th Jan 2017, then it is disabled. -------------- next part -------------- An HTML attachment was scrubbed...
