Yeah. Core nodes will follow the new longer chain tip and knots nodes will stay on the old block waiting for someone to add to it because they think that new block is invalid. The core nodes and the knots nodes will follow different chains. And when 1 chain becomes 2 chains in a way where they can never merge or reconcile it is called a hard fork. I can't tell if you are fucking with me because this is pretty basic.

I mean, I’m not piping in pretending to be knowledgeable. I’m just concerned and curious as a green pleb. To my understanding from everything I’ve taken in on the matter, please correct me if I’m mistaken: -BIP110 only implements its filter on spam if greater than 55% of people run Knots —Otherwise, it defaults to the rules of Core to prevent a fork, and keeps identical chain data ——I assumed that they don’t want to fork anything completely, and make the Knots nodes into the new Bitcoin Cash, unless more than the majority agree it necessary Also, I assume all my cold storage is safe even if a hard fork does occur so long as I don’t move it to the post-fork? But it is worrisome to me talking about rewriting the chain data in the past in any sense. Sounds more than risky
