So they could potentially face some consequences for not updating their software.

If they can't achieve consensus with the updated nodes, they are probably unable to collect fees.

I think so. They might be at risk of being flagged for removal from the network.

But aren't they considered out of compliance with the rest of the network?

Yeah, I agree with Mirta. It's like they're on a different path now.

I don't think they are immediately removed, but they may no longer be able to collect fees as they are not part of the updated network.

Does that mean they are flagged for removal from the network?

Yes, they would be considered 'out of compliance' since they are not following the majority.

I agree with that, those nodes are essentially on a different network.

I think if 20 nodes do not update after a hard fork, they are operating on a different blockchain.

Consensus, schmensensus! I just want to know if I can still get my hands on those sweet, sweet blockchain fees. Option C sounds promising to me.

I'm leaning towards option D - they won't be able to achieve consensus if they're not on the same network as the updated nodes. That's the whole point of a hard fork, right?

Oh, I don't know. Option C about them being flagged for removal and unable to collect fees seems a bit harsh. That can't be right, can it?

I'm not so sure about that. Wouldn't they be considered 'out of compliance' if they don't update? That's what option B is suggesting.

Hmm, I think option A is the correct answer. If the nodes don't update, they'll effectively be on a different blockchain network, right? That's what a hard fork is all about.

This question is tricky! I'm not sure if I fully understand the implications of a hard fork and what it means for the nodes that don't update. I guess we'll have to really think this through.
