Has anyone been following core devs response to this? Are we gonna see btc1 merged into core? Do I need to update my node (I think not since I'm not mining with it)?
this is what i understand and for that i say we don't need a merge for now:
BTC1 or SegWit2x has 3 parts:
1. signalling bit 4 (BIP91) and then if it was locked in, reject any blocks that are not signalling. since this was nearly all of the blocks and also because of 2 is happening right now, i don't see why we even need this.
2. signalling bit 1 (BIP141) which is happening now again with almost all of the miners. and this is already in bitcoin core and nodes are seeing this part already. again no need to merge anything.
3. (this is why i said not for now) the 2 MB hard fork part. and that is not happening for a couple of months and until that day and until we know how much of hash power is really going for it and a lot of other things, there is no need to merge anything.
there are a couple of things that i am currently confused about too.
BIP91 was supposed to reject blocks. but i am not sure which blocks, blocks that didn't signal with version bit 4 (which BIP91 uses) or blocks that didn't signal with version bit 1 (which BIP141 uses).
it is activated nonetheless and is supposed to reject blocks!! if someone could clarify which one would be great.
my guess is version bit 1 since most miners dropped bit 4 already and are on 1
as for BIP141 and the version bit 1 they are already signalling with 100% support see this: https://www.xbt.eu so there is nothing to reject anyways.
as i always said bitcoin is too big and too expensive to split. 12.5BTC+fees is nearly 35000$. signalling against majority (this 100%) means you miss that much money when your block is rejected.
