electrs: adapt to version 0.9.0
- `waitfornewblock` was previously not included in the public RPC
  whitelist because it's reserved for testing and marked as hidden
  in bitcoind.

- electrs changed its verbosity settings. `-vv` is now the best choice
  for normal usage.

- bitcoind option `dataDirReadableByGroup` is now unused.
  Because it can be valuable for other use cases and implementing
  it is intricate, we're keeping it for now.

- test: keep `nc` connection open because otherwise the electrs
  RPC server would now close the connection before sending a response.

Examples

The easiest way to try out nix-bitcoin is to use one of the provided examples.

git clone https://github.com/fort-nix/nix-bitcoin
cd nix-bitcoin/examples/
nix-shell

The following example scripts set up a nix-bitcoin node according to configuration.nix and then shut down immediately. They leave no traces (outside of /nix/store) on the host system.
By default, configuration.nix enables bitcoind and clightning.

Run the examples with option --interactive or -i to start a shell for interacting with the node:

./deploy-qemu-vm.sh -i

Tests

The internal test suite is also useful for exploring features.
The following run-tests.sh commands leave no traces (outside of /nix/store) on the host system.

git clone https://github.com/fort-nix/nix-bitcoin
cd nix-bitcoin/test

# Run a node in a VM. No tests are executed.
./run-tests.sh vm
systemctl status bitcoind

# Run a Python test shell inside a VM node
./run-tests.sh debug
print(succeed("systemctl status bitcoind"))
run_test("bitcoind")

# Run a node in a container. Requires systemd and root privileges.
./run-tests.sh container
c systemctl status bitcoind

# Explore a single feature
./run-tests.sh --scenario electrs container

# Run a command in a container
./run-tests.sh --scenario '{
  services.clightning.enable = true;
  nix-bitcoin.nodeinfo.enable = true;
}' container --run c nodeinfo

See run-tests.sh for a complete documentation.

Real-world example

Check the server repo for https://nixbitcoin.org to see the configuration of a nix-bitcoin node that's used in production.

The commands in shell.nix allow you to locally run the node in a VM or container.

Flakes

Flakes make it easy to include nix-bitcoin in an existing NixOS config. The flakes example shows how to use nix-bitcoin as an input to a system flake.

Run nix run or nix run .#vm from the nix-bitcoin root directory to start an example nix-bitcoin node VM. This command is defined by the nix-bitcoin flake (in flake.nix).
