860a1ea07467788473f0a83edc4d7a02d8ad3c1a guix: use Rust 1.70 for release builds (Antoine Poinsot) Pull request description: This is prep work for #597, which bumps the MSRV of the GUI to 1.70. We are being pulled over in two different directions when it comes to our reproducible builds. On the one hand we need to target reasonably old glibc versions in order to be compatible with older systems. On the other hand the immaturity of the Rust ecosystem makes us require bleeding edge versions of the compiler. With Guix to get the newer versions of the compiler we need to also bump the glibc version. This was not a sustainable situation. I was planning for a long time to cleanup our reproducible builds. To create a proper Guix package for both the daemon and the GUI using the build system they provide. I had envisioned this way i could rewrite the inputs of the Guix package to use an older glibc, while being able to bump the Guix time-machine. It would even have allowed us to perform Windows builds inside Guix! And who knows i could even have attempted to perform Apple ones too. Unfortunately it turned out to be more complicated than that. I couldn't manage to get my package to compile using an older glibc. Some details about some of my failed attempts can be found there: https://lists.gnu.org/archive/html/help-guix/2024-04/msg00056.html. Instead of wasting more time on this, backport the newer Rust declarations from up-to-date Guix to Guix-of-our-time-machine.

Liana
The missing safety net for your bitcoins.
About
Liana is a simple Bitcoin wallet. Like other Bitcoin wallets you have one key which can spend the funds in the wallet immediately. Unlike other wallets, Liana lets you in addition specify one key which can only spend the coins after the wallet has been inactive for some time.
We refer to these as the primary spending path (always accessible) and the recovery path (only available after some time of inactivity). You may have more than one key in either the primary or the recovery path (multisig). You may have more than one recovery path.
Here is an example of a Liana wallet configuration:
- Owner's key (can always spend)
- Any 2 keys from the owner's spouse and two kids (after 1 year)
- A third party, in case all else failed (after 1 year and 3 months)
The lockup period is enforced onchain by the Bitcoin network. This is achieved by leveraging timelock capabilities of Bitcoin smart contracts (Script).
Liana can be used for trustless inheritance, loss protection or safer backups. Visit our website for more information.
Usage
Liana is available on Windows, Mac and Linux. To install and start using it see
doc/USAGE.md. A more accessible version of Liana is also available as a web
application here.
If you just want to quickly try out Liana on Bitcoin Signet, see doc/TRY.md.
Hacking on Liana
Liana is an open source project. It is hosted at Github. Contributions are very welcome. See here for guidelines. Liana is separated in two main components: the daemon and the Graphical User Interface.
Liana daemon
The daemon contains the core logic of the wallet. It is both a library (a Rust crate) that exposes a command interface and a standalone UNIX daemon that exposes a JSONRPC API through a Unix Domain Socket.
The code for the daemon can be found in the src/ folder at the root of this repository.
Liana GUI
The GUI contains both an installer that guides a user through setting up a Liana wallet, as well as
a graphical interface to the daemon using the iced library.
The code for the GUI can be found in the gui/src/ folder.
Security

that could potentially impact the security of users' funds.
