Is core planning on integrating Segwit2x?
No.
If no, what exactly is core planning in regards to a BIP148 chain split or a Segwit2x hard fork, if anything?
Nothing. Many of the Core developers believe that both BIP 148 and Segwit2x will fail. In the event of a chain split, there will be an alert posted on bitcoin.org (there's going to be one anyways because of the possibility of a chain split) with instructions on how to make your node follow the chain you want it to follow. It's very easy to do by using the
invalidateblock RPC command.
Thank you.
I am running Luke's BIP148 and mining at Slushpool/UASF since it was available because it seemed that nothing would break the deadlock and the BIP141 activation threshold was ridiculously set to 95%. I realize I'm in the minority on this, but I hope there's enough of guys like me willing to do something to get Segwit activated one way or another.
Large miners claim they will be running 2x and activating SegWit by July 25, which will moot the point of BIP148. This is 100% fine by me.
I will return to running the original core after Segwit is guaranteed locked in. Hopefully the forking hash to 2x will be minimal and we won't end up with CoreCoin and BitmainCoin.
