d551aeeeacf5356a0ba25f4929230dd099b01c32 electrum: consider invalidated blocks for reorgs (Michael Mallan)
86965c188e29191b60da51ce7d998157e1d50f77 electrum: common ancestor is before first changed block (Michael Mallan)
Pull request description:
The common ancestor is the highest block that is strictly lower than the first change.
When finding the point of change, we can take the first height with any change (including an invalidated block) rather than the first height with a new block, which avoids a loop. The height found in both cases (loop vs no loop) should be almost always the same as we apply the update to our local chain before finding the common ancestor, but perhaps in a test if there's a reorg down to 0 and the chain update only contains invalidated blocks and no new blocks, then checking for the first invalidated block would be better as there would be no new blocks to find and the reorg would be undetected.

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. Most regular contributors hang out on our Discord. Join us there if you have any question about contributing.
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
See SECURITY.md for details about reporting a security vulnerability or any bug
that could potentially impact the security of users' funds.
