Damn, I was on mobile and didn't see the previous history. It's my understanding that the target is 75% before bitcoin unlimited will try and "take over".
/r/btc is excited about it. Apparently there's a civil war between /r/bitcoin and /r/btc and the broader bitcoin community.
The issue is bitcoin fees have skyrocketed at an almost exponential pace and transaction times are way up.
Right now a "normal" fee from last year results in a ~24hr wait time
The core group has a "solution", and the Unlimited group claims to have a better one (as well as a list of grievances such as the core group being irresponsibly slow to react, also that their solution doesn't scale and is a stopgap etc etc).
I'm no expert though, if anyone could chime in with more info I'm all ears.
Do they need a supermajority, like 75% or 90%, before something interesting happens?
