summary

Miniscript provides a template language that maps directly back to Bitcoin Script, giving a one-to-one correspondence with Bitcoin Script so on-chain outputs are auditable. It makes spending conditions computable (automatic fee/size estimates, detect whether a particular key is ever required, simplify time-locked branches) and composable (replace a public-key leaf with an arbitrary sub-tree). Example: a 2-of-3 primary branch with an emergency key usable only after 1000 blocks; libraries like bdk and wallets like Specter can interoperate using these parsed policies.
