Based on Jinse, Bitcoin Core v30 increased the OP_RETURN data limit, not to accommodate Ordinals, but to support BitVM development. Citrea's Clementine bridge, the first zkRollup on Bitcoin using BitVM, required 144 bytes of on-chain data for validation, exceeding the previous 83-byte limit. Due to Bitcoin Script limitations, this data had to be in scriptPubKey, not witness, leading to a workaround that created unspendable UTXOs. Core developers, recognizing the long-term importance of BitVM for Bitcoin's L1 innovation, opted to increase the OP_RETURN limit as a harm reduction strategy. This change reflects a proactive move to support future infrastructure needs, not speculative use cases like Ordinals.
