I still don’t fully grok the attack. I can imagine you’re sick of the discussion (I saw you credited on the BIP website). Just hoping you’ll help me with more details.

I’ve read the BIP writeup. To me, it sounds like a side protocol like ordinals / inscriptions. Old node software versions would see it as meaningless data that only means something to the participating users.

Like I’m watching a baseball game and I see hand signs but don’t realize what they mean.

Is it really an attack though? Does it improperly change network incentives? Censor transactions? Some other harm to the base chain?

I get Lyn Alden’s point that we want the base chain to be resistant to change, but, unless I’m missing something, nothing appears to be changing from the perspective of old node software.

It’s like a private group of people coordinating to use the blockchain to pass messages to each other.

Again, appreciate any insight you can provide. 🙏
