The P.R. you reference that adds BIP 322 to bitcoin core is out of date. I believe it was closed in favour of this one - https://github.com/bitcoin/bitcoin/pull/24058.
Hey, any update on this project? When is it kicking off?
@wip-abramson we've been challenged trying to set up a meeting that works for Japan, California, and London. Doesn't seem to be working. Planning may be two meetings, one with @kallewoof and one with you. Is there a 9am meeting PDT hole in your schedule anytime soon?
Implementation in scala I created: https://github.com/bitcoin-s/bitcoin-s/pull/3823
Last week with met in Zoom with @kallewoof. Let me know if you want the audio recording from that meeting.
We are meeting tomorrow (Monday 9am PDT) with @wip-abramson. Contact me if you have not received Zoom details. I will record it as well.
If anyone could review this P.R. which is a WIP of bip322 in the buidl-python library - https://github.com/buidl-bitcoin/buidl-python/pull/140
That would be much appreciated!
We've begun to draft some use cases for BIP-322 at https://hackmd.io/KR5ALrSSQO6eyrnUBJreeA — please feel free to add more, or add comments (in the view interface) if you have constructive criticism. In particular, the "proof of reserve" use cases have had some active criticism in the past that we'd like to either capture or address.
Our initial goal is to support requirements for our libraries and reference implementation for BIP-322, but I also want to publish this in some final form later this summer.
There is a thread starting today on Bitcoin-Lev list BIP-322: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-August/020844.html

I'm the author of that post - I also happen to be a C++11 dev. I am willing to help out with a standalone BIP322 C++ implementation.
BIP-322 is a proposal originally by Kalle Alm (@kallewoof) to leverage the Bitcoin scripting language (ambiguously just called
bitcoin script
) to enable the signing of arbitrary messages using the same keys & scripts that Bitcoin uses for transactions.In particular, BIP-322 extends the old single-key signing of messages (using the now off-by-default
signmessage
&verifymessage
rpc api calls) which only worked with legacy scripts like Pay-to-Public-Key-Hash (P2PKH), to allow signing messages using any Bitcoin script wich can conceivably spend (in particular Pay-to-Witness-Script-Hash (P2WSH).In older versions of bitcoin-core's
bitcoind
, this is the way thesignmessage
andverifymessage
calls worked (example from LBTCftCL):The goal of this project is to implement BIP-322
signmessage
andverifymessage
functions as a C++ Command Line Interface (CLI) app, in a form that allows for the offline signing of messages, with no dependencies on bitcoin-core'sbitcoind
server, but leveraging the more secure and supported bitcoin-core libraries like secp256k1 and likely btcdeb.Community Project milestones:
