08:14 < darosior> I think it should rather be Lightning to adapt to Miniscript than the opposite. FWIW i had a draft proposal last year and it's a topic i proposed to be discussed during the lndev meetup
14:34 < darosior> sipa: so the descriptor parsing code currently doesn't cache pubkeys. But we need a SigningProvider with filled pubkeys to infer a descriptor. Does that seem reasonable to you to always cache public keys at parsing time if under P2WSH context?
14:39 <@sipa> hmm, we don't?
14:39 <@sipa> achow101 probably knows better
14:41 < darosior> We only cache privkeys at parsing time AFAICT
14:57 <@sipa> i don't see any issue with caching pubkeys
15:22 < achow101> darosior: the parent xpub will be cached which allows for quick derivation of child pubkeys
15:23 < achow101> if hardened derivation is in use, then child pubkeys will be cached
15:23 < darosior> Yeah but for infering Miniscript descriptors i need a keyid -> pubkey mapping to get pubkeys from keyhashes
15:25 < darosior> How is it done currently, say for the pkh() descriptor?
15:26 < achow101> we re-derive (using the cache) and get the pubkeys into a SigningProvider
15:26 < achow101> then use that with InferDescriptor
15:30 < darosior> Thanks, i'll see if i can use the same logic for inferring ms descriptors
