TechFlow news: Ordinals founder Casey tweeted that runes and inscriptions are as programmable as Bitcoin, and improvements in Bitcoin's expressiveness similarly enhance the capabilities of runes and inscriptions.
For example, OP_CHECKTEMPLATEVERIFY can organize open mints into an OP_CTV tree, expanding to leaf UTXOs containing runes.
SIGHASH_GROUP flexibly allows signing commitments to combinations of multiple inputs and outputs, making it easier to transfer runes to the Lightning Network.
Standardizing the Taproot signature appendix and enabling carving of unstructured data allows inscriptions within a single transaction, without requiring submission and revelation of two separate transactions.
