this narrative is not correct. lifting the placebo filter doesn't allow large OP_RETURNs to suddenly start happening. we are not sitting around anxiously waiting for core to push the big evil button, after which it will be possible for the first time. it already happened. the largest OP_RETURN on bitcoin happened 298 days ago and it was 79,870 bytes, which is over 7 times bigger than your profile picture. it appears to have been submitted to slipstream, meaning someone told it directly to a miner and bypassed the mempool completely. the filter didn't work. it looks like it was a runestone, so it's probably a picture. if you don't have pruning enabled, it's on your computer right now.

What's the largest OP_RETURN payload ever created? In terms of pushed bytes after the OP_RETURN, not in terms of total transaction size, and not in...

and you seem totally lost about what citrea even does. its sequencer posts zero knowledge proofs onto bitcoin of transactions that happened on a separate blockchain. it does not post the transactions themselves. this is a GOOD thing if you don't want people doing ethereum-type stuff directly inside the bitcoin blockchain.
