The 5-6 mining pools will stay on a conference call to insure BIP-110 doesn't have a chance. There won't be a game of chicken or a "red" or "blue" button.

Even if the first block after activation is BIP-110 eligible (unlikely with 1-2% of the hash) then they will just wait for the second block. Then next block is not BIP-110 eligible and BIP-110 forks off, then they just chill on the conference call for another hour until 6 more blocks are mined on their chain to be sure it's over then they hang up and go to bed.

Here’s how August 7th or 8th will play out:

The 5 or 6 largest mining pools will gather on a conference call at block 961,632.
The decision will be unanimous: “We’re not flipping the bit.”

Moments later, the next block will be an OP_IF JPEG block featuring Luke/Mechanic/Kratter AI art (which BIP-110 nodes will block).

BIP-110 nodes will then split off and continue on their own chain mining 5-10 blocks a day until the next difficulty adjustment.

And, for the laughs, spammers will likely be the first to test the new Ordinals method on the BIP-110 chain so every BIP-110 block contains ordinals spam.

They don't have to build everything from scratch. They need to update inscription software, parsers and indexers. AI can update the code in a minute. It's a mild nuisance for them that does nothing to stop them.

New filters won't do anything when the 5 mining pools can just continue to not use the filters in their custom version of bitcoin software.

Core fucking sucks, it's their fault for releasing shitty consensus Taproot software but BIP-110 sucks even more because it doesn't do anything besides limit op return. It doesn't even stop ordinals.

They will be forking off on August 8th I believe.

BIP-110 doesn't stop spam.
I'd support it if it stopped spam.
But it doesn't.
They already have work arounds for ordinals ready to go live.
