Some people seem to want to argue that there is already CSAM in Bitcoin's blockchain. This is false. Bitcoin today does not support images at all - only arbitrary data up to 80 bytes (or 95 in the coinbase). Exploits like "Inscriptions" work by _misinterpreting_ script code, and _bypassing_ existing policy rules. They are not actually storing images, but merely putting gibberish code on the chain, which they later themselves (not Bitcoin) _misinterpret_ as images. This distinction is very real and relevant. If you don't differentiate between "data that can be misinterpreted to produce CSAM" and "data that correctly interpreted displays CSAM", then literally _all data_ is CSAM, with _no exceptions at all_. This tweet would be CSAM. Google's logo would be CSAM. Your phone's operating system would be CSAM. Literally anything _can_ be misinterpreted as CSAM.

Bitcoin actually does support arbitrary data greater than 80 bytes. Your node will relay it too, after a miner mines it.
I would rather put the onus on the publicly traded miner corporation with a board that accepted the transaction out of band on the hook, that any solo or pool miner being forced to include it. But that's just me.
So here's an example for how to read image from witness inscription (I promise it's not CSAM): bitcoin-cli getrawtransaction "584b6d204fcf6e2a3dd82a9adc55890447a09b534ab7d725a7353aecf547bcbf" 1 | jq '.vin[0].txinwitness[1]' | awk -F '0063036f726401010a696d6167652f776562705202' '{gsub("4d0802", "", $2); print substr($2, 7)}' | xxd -r -p > test.webp View quoted note →

I would rather not establish precedent that node operators are responsible for the data on the block chain. That opens up a trivial attack vector by literally anybody. Making the argument that it’s a public space and therefore individual people aren’t responsible is much safer/robust over the long term

Data is just 0s and 1s. If you choose to interpret and decode it as a JPEG that’s your problem…

> Bitcoin today does not support images at all Are you suggesting v30 and higher will parse the uploaded images at the client level? I thought the Bitcoin Core GUI is strictly a wallet/block explorer interface and shall never render or interpret image data contained in blockchain transactions.

He was very public back then accusing everyone without ever disclosing his setup and owning up to his mistake of keeping his coins in a hot wallet. Guess you werent around back then

If someone gives me directions to the beach, and I follow those directions and I end up at the beach, then I haven't misinterpreted anything.
Bitcoin does not intentionally support images, but intentions many times depart from reality. Unintentionally supporting arbitrary data, IS a way to support images, among other things. And yes, many arbitrary data storage solutions indirectly support images, including for sure a phone's OS, among other devices. And some images can fall into the CSAM category, thus being illegal. It seems unnecessary to force arguments to deny the obvious.

Ok. Did that. I’m still not sure where you think I went off base.

Yes but you could blame them for a crowded beach existing. Which is a genuine state of existence for a beach. Basically it's amorphous and messy, and attempts to draw clear lines are pretty ambitious.

What is the best outcome here? Too few people upgrading to V30 and core deciding to lower the op limit back to 80 in V31 because of poor adoption?
People realize #knots means Luke gets richer and we don’t want ONE PERSON with that much control. It goes against everything #Satoshi stood for. Luke is a conman. image
Quit exploiting everyone’s over CSAM 1. You weren’t bitching at all when everybody was putting pictures Trump on there. 2. You just don’t want the EPSTEIN FILE on #blockchain 3. You had your chance, get ready to burn. 🔥
Samesies. I had no idea what a jerky really was until he started posting here so give me a target and I’ll take it down. 😂😂😂
So he’s a loser. And a bad one. Got it. #CryHarder @Luke Dashjr You want a #blockchain #war and refuse to speak with others … your reckoning is coming 1. You don’t mess with *anyone* in #Bitcoin and expect to undermine them A. Luke did. 2. Luke was given multiplicity of chances to be a man and admit he was wrong on multiple things. He declined. 3. #Satoshi stood for far more than this callous tiny acorn ever will.
