And your first block signalling segwit support
Indeed it is. Unfortunately segwit voting doesn't seem to go much higher than 30% so I guess it may take a while until we see segwit activated.
Aye. At this stage watching percentage voting yes is pointless as it is purely going to depend on number of large pools supporting it rather than absolute percentage. If, and, as soon as, another pool supports segwit the percentage will jump up and stabilise with their hashrate percentage. So it's been static for almost a month since the same sizeable pools have been featuring in the yes vote.
