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 terms of amount “burnt”. Also just the payload itself, so excluding the data push op codes (e.g. OP_PUSHDATA4 ).
Since this will be a non-standard transaction, there are two categories: the largest IsPushOnly() and the largest !IsPushOnly(). See Why do standard OP_RETURN outputs also need to be IsPushOnly()?
I’m curious if the latter is used at all, but my question pertains to the former. That is, something a miner can create by setting -datacarriersize and optionally increasing MAX_STANDARD_TX_WEIGHT and no other patches.
An additional distinction could be made between the largest coinbase and non-coinbase OP_RETURN.
