fa0fa0f700refactor: Revert "disable self-assign warning for tests" (MarcoFalke)faed118fb3build: Bump clang minimum supported version to 17 (MarcoFalke) Pull request description: Most supported operating systems ship with clang-17 (or later), so bump the minimum to that and allow new code to drop workarounds for previous clang bugs. (Apart from dropping the small workaround, this bump allows the `ci_native_nowallet_libbitcoinkernel` CI to run on riscv64 without running into an ICE with clang-16.) This patch will only be released in version 31.x, next year (2026). For reference: * https://packages.debian.org/bookworm/clang-19 * https://packages.ubuntu.com/noble/clang (clang-18) * CentOS-like 8/9/10 ship clang-17 (and later) via Stream * FreeBSD 12/13 ship clang-17 (and later) via packages * OpenSuse Tumbleweed ships with https://software.opensuse.org/package/clang (clang21); No idea about OpenSuse Leap On operating systems where the clang version is not shipped by default, the user would have to use GCC, or install clang in a different way. For example: * https://packages.debian.org/bookworm/g++ (g++-12) * https://packages.ubuntu.com/jammy/g++ (g++-11) * https://apt.llvm.org/, or nix, or guix, or compile clang from source, ... *Ubuntu 22.04 LTS does not ship with clang-16 (the previous minimum required), nor with clang-17, so one of the above workarounds is needed there.* macOS 14 is unaffected, and the previous minimum requirement of Xcode15.0 remains, see also919e6d01e9/depends/hosts/darwin.mk (L3-L4).

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.
