PSBT key path cleanups #13723

sipa · 2018-07-20T07:15:14Z

This PR adds "key origin" (master fingeprint + key path) information to what is exposed from SigningProviders, allowing this information to be used by the generic PSBT code instead of having the RPC pull it directly from the wallet.

This is also a preparation to having PSBT interact with output descriptors, which can then directly expose key origin information for the scripts they generate.

Concept ACK

Thanks for taking another look at this code

Partial utACK. Nice refactors that improve code readability. Some nits regarding code style.

Shouldn't this change be part of the earlier " Generalize PublicOnlySigningProvider into HidingSigningProvider" commit?

It could be, but doesn't matter. There is no bip32 information in SignatureData until this commit.

achow101 · 2018-07-20T23:11:58Z

src/script/sign.cpp

In commit "Make SigningProvider expose key origin information"

You should change address to keyid in this commit instead of "Generalize PublicOnlySigningProvider into HidingSigningProvider"
