Ryanofsky [suggested](https://github.com/bitcoin/bitcoin/pull/26728#issuecomment-1867721948) A `unused(KEY)` descriptor which allows for a key to be specified, but produces no scripts. These can be imported into the wallet, and subsequently retrieved with `gethdkeys`. Additionally, `listdescriptors` will output these descriptors so that they can be easily backed up. In order to make it easier for people to add HD keys to their wallet, and to generate a new one if they want to rotate their descriptors, an `addhdkey` RPC is also added. Without arguments, it will generate a new HD key and add it to the wallet via a `unused(KEY)` descriptor. If provided a private key, it will construct the descriptor and add it to the wallet. See also: https://github.com/bitcoin/bitcoin/pull/26728#issuecomment-1866961865 Based on #29130 as `gethdkeys` is useful for testing this.

Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires several hundred gigabytes or more of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to several days or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt(GUI) orbin/bitcoind(headless)bin/bitcoin(wrapper command)
The bitcoin command supports subcommands like bitcoin gui, bitcoin node, and bitcoin rpc exposing different functionality. Subcommands can be listed with bitcoin help.
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
