Update to bitcoind 23.x (#2466)
This release of bitcoind contains several bug fixes that let us simplify our fee bumping logic: - fixed a bug where bitcoind dropped non-wallet signatures - added an option to fund transactions containing non-wallet inputs It also has support for Taproot, which we want in eclair.

This means that instead of re-implementing them, Eclair benefits from the verifications and optimisations (including fee management with RBF/CPFP, ...) that are implemented by Bitcoin Core. Eclair uses our own [bitcoin library](https://github.com/ACINQ/bitcoin-kmp) to verify data provided by Bitcoin Core.
|
||||
|
||||
:warning: This also means that Eclair has strong requirements on how your Bitcoin Core node is configured (see below), and that you must back up your Bitcoin Core wallet as well as your Eclair node (see [here](#configure-bitcoin-core-wallet)):

- Eclair requires Bitcoin Core 0.20.1 or 0.21.1. (other versions of Bitcoin Core are *not* actively tested - use at your own risk). If you are upgrading an existing wallet, you may need to create a new address and send all your funds to that address.

### Backup

|

You need to backup:
|
||||
- your Bitcoin Core wallet
|
||||
- your Eclair channels

* your Bitcoin Core wallet
|
||||
* your Eclair channels
|

|

For Bitcoin Core, you need to backup the wallet file for the wallet that Eclair is using. You only need to do this once, when the wallet is
|
||||
created. See [Managing Wallets](https://github.com/bitcoin/bitcoin/blob/master/doc/managing-wallets.md) in the Bitcoin Core documentation for more information.

### Bitcoin Core 23 or higher required
|

|
||||
This release adds support for Bitcoin Core 23.x and removes support for previous Bitcoin Core versions.
|
||||
Please make sure you have updated your Bitcoin Core node before updating eclair, as eclair won't start when connected to older versions of `bitcoind`.
