Hi
Assessing what should be sent to this mailing list is difficult. We don't want
to be bombarded with full on company promotional materials obviously but then
at the same time only focusing on contentious consensus changes at the expense
of everything else just gives a warped view to readers of this list of what is
happening in the community and what 99 percent of Bitcoin devs are working on.
One example of many is Miniscript. In this excellent blog post [1] by Salvatore
Ingala he explains the work he is doing to get Miniscript support in the Ledger
hardware wallet (or "signing device" [2], hat tip nvk). Miniscript has been in
the works for a number of years now and the first of multiple Miniscript
related pull requests was recently merged into the Bitcoin Core wallet [3].
This wasn't included in the recent Bitcoin Core 23.0 release [4] but one would
expect it to be included in the next major release (24.0).
Salvatore explains that to start enabling Miniscript support in Ledger only
requires ~20 lines of code but there is additional complexity that isn't
covered by the included code snippet. And of course the Policy to Miniscript
compiler(s) don't (yet) support Taproot trees of scripts so we are talking
primarily Bitcoin scripts pre-Taproot. He also includes a short video of what
the Policy/Miniscript user experience might look like on a Ledger Nano.
For those who are interested in learning more about Miniscript stickies-v is
hosting a Bitcoin Core PR review club on Miniscript on May 18th [5].
Disclaimer: I have personal views on hardware wallets/signing devices as anyone
does but I do not receive funding from any particular company or product in the
space.
