Bitcoin Core v30 has raised the OP_RETURN data limit to facilitate the development of BitVM, rather than to support Ordinals. The change was necessary for Citrea's Clementine bridge, the first zkRollup on Bitcoin using BitVM, which required 144 bytes of on-chain data for validation, surpassing the previous 83-byte limit. Due to Bitcoin Script constraints, this data needed to be in scriptPubKey, not witness, resulting in unspendable UTXOs. Recognizing BitVM's potential for Bitcoin's Layer 1 innovation, core developers increased the OP_RETURN limit as a harm reduction measure, focusing on future infrastructure rather than speculative applications.
