Welcome to Floresta, a lightweight Bitcoin full node implementation written in Rust, powered by Utreexo a novel dynamic accumulator designed for the Bitcoin UTXO set.
This project is composed of two parts, libfloresta and florestad. libfloresta is
a set of reusable components that can be used to build Bitcoin applications. florestad is built on top of libfloresta to provide a full node implementation, including a watch-only wallet and an Electrum server. If you just want to run a full node, you can use florestad directly, either by building it from source or by downloading a pre-built binary from the releases.
If you want to use libfloresta to build your own Bitcoin application, you can find the documentation here.
If you want to discuss this project, you can join our Discord server here.
You'll need Rust and Cargo, refer to this for more details. Minimum support version is rustc 1.74 and newer.
Once you have Cargo, clone the repository with:
git clone https://github.com/Davidson-Souza/Floresta.gitgo to the Floresta directory
cd Floresta/and build with cargo build
cargo build --release --bin florestad
# Optionally, you can add florestad to the path with
cargo install --path ./florestadIf you're using Nix, you can add Florestad to your system with its overlay.
{
#Here you declare the import for your flake
inputs.florestad = {
url = "github:Davidson-Souza/Floresta";
inputs = {
nixpkgs.follows = "nixpkgs";
flake-parts.follows = "flake-parts";
};
};
outputs = inputs @ { self, ... }:
{
imports = [
{
nixpkgs.overlays = [
# Here you use the floresta overlay with your others
inputs.florestad.overlays.default
];
}
];
};then Florestad will be available just like any other package with
pkgs.florestadBut if you just want to test it or quickly run a instance you can do
$ nix run github:Davidson-Souza/FlorestaRight now, this project is working on signet only. Mainnet support is still a todo thing. You can get some signet coins here and just play around with it.
Copy config.toml.sample to config.toml, and fill up your xpubs and addresses that you intend to track, and then run with
florestad -c config.toml --network signet runor
./target/release/florestad -c config.toml --network signet runor
cargo run --release -- -c config.toml --network signet runcargo buildThere's a set of unit tests that you can run with
cargo testThere's also a set of functional tests that you can run with
pip3 install -r tests/requirements.txt
python tests/run_tests.pyContributions are welcome, feel free to open an issue or a pull request.
If you want to contribute but don't know where to start, take a look at the issues, there's a few of them marked as good first issue.
Here's some Guidelines:
- Has to compile.
- Has to run.
- Use pre-commit for the language that you're using (if possible 👍).
You can accomplish that using our flake.nix for development.
If you already have Nix you just need to do:
$ nix developand use our flake for development with include
- nix(fmt) and rust(fmt) pre-commit.
- Rust Msrv(1.74.0).
- Clippy and some libs so rust can compile.
- Typos for good spelling.
If you do not have Nix Check their guide.

One of the most challenging parts of working with Bitcoin is keeping up with the consensus rules. Given it's nature as a consensus protocol, it's very important to make sure that the implementation is correct. Instead of reimplementing a Script interpreter, we use rust-bitcoinconsensus to verify transactions. This is a bind around a shared library that is part of Bitcoin Core. This way, we can be sure that the consensus rules are the same as Bitcoin Core, at least for scripts.
Although tx validation is arguably the hardest part in this process. This integration can be further improved by using libbitcoinkernel, that will increase the scope of libbitcoinconsensus to outside scripts, but this is still a work in progress.
