According to TechFlow, Casey, founder of Ordinals, said in a tweet that runes and inscriptions are as programmable as Bitcoin, and the improvement of Bitcoin's expressiveness has also improved the expressiveness of runes and inscriptions. For example, OP_CHECKTEMPLATEVERIFY can organize open minting into an OP_CTV tree, which expands to the leaf UTXO containing runes. SIGHASH_GROUP can flexibly commit to a combination of multiple inputs and outputs with signatures, making it easier to transfer runes to the Lightning Network. In addition, standardizing the Taproot signature appendix and allowing the engraving of unstructured data can be inscribed in a single transaction without submitting and revealing two transactions.
