I am a little bit confused about the threshold. Is it 80% or 95%? In some threads here, I have seen users mentioning 95% as the necessary consensus needed to activate Segwit2x. And here, you are talking about 80% hashrate. So which one is correct?
The original Segwit (not Segwit2x) specification needs 95% of the blocks signalling for it to be activated.
Segwit2x includes basically two changes: one is that the threshold is lowered to 80%, and the other one is that in 6 months, a hardfork to increase the block size to 2 MB is scheduled.
But what I was talking about here isn't even that lower threshold. In the New York Agreement (the agreement that led to Segwit2x) the participant miners were said to have 80% of the Bitcoin hashrate. That's what I want to know - if this number is real (and really all pools signal for it), we will see it this Monday or Tuesday.
