So much for KNC's
very brave choice to be the first defector from Bitcoin Core.
What a shame, I would have been so happy to buy their products with my XTcoins.
As of right now, BIP 100 is also defecting from Bitcoin Core.
There's 3 options:
1) No change (bitcoin core as it stands today)
2) Bitcoin With BIP100 Hardfork (doesn't have an implementation in ANY client)
3) Bitcoin With BIP101 Hardfork (has an implementation in Bitcoin XT client)
Unless BIP100 actually get implemented into Bitcoin core, it's the same situation as BIP101 with XT. XT as of today is literally just Core+BIP101. The client has other features, but the only protocol level change is BIP101 enforcement once certain criteria are met.
XT is more than just Core+BIP101 - it's other client changes and not tested at the level core is when implementing changes.
I've personally not checked where it is at with handling > 32MB blocks either - since that is also a hard fork to the protocol.
What 'would' have happened is Core 'would' have gone BIP101 or BIP100 - since of course if they ignore both they, the pools themselves would 'resolve' the issue.
However, since BIP100 already has ~60% of the blocks and with a Bitmain change would be over 80% of the blocks, Core has no choice but to go BIP100 or cause more issues than Gavin.
FYI it was a Bitmain person who suggested adding /BIP100/ to me ... so we did
The voting we are doing is to say we don't want XT or BIP101 and that Core should get around to doing what jgarzik suggested for core
