Firedancer 🔥💃

Firedancer is a new validator client for Solana.

• Fast Designed from the ground up to be fast. The concurrency model is borrowed from the low latency trading space, and the code contains many novel high performance reimplementations of core Solana primitives.
• Secure The architecture of the validator allows it to run with a highly restrictive sandbox and almost no system calls.
• Independent Firedancer is written from scratch. This brings client diversity to the Solana network and helps it stay resilient to supply chain attacks in build tooling or dependencies.

Documentation

If you are an operator or looking to run the validator, see the Getting Started guide in the Firedancer docs

Developing

The below describes building Frankendancer from scratch and running it optimized on a stock Linux image. You will need basic development tools like make, gcc along with rustc, and clang.

Frankendancer currently only supports Linux, and requires a kernel newer than v5.7 to build.

$ sudo dnf groupinstall development
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Then you can clone and build the application from source,

$ git clone --recurse-submodules https://github.com/firedancer-io/firedancer.git
$ cd firedancer
$ ./deps.sh
$ make -j run

The make run target runs the fddev dev command. This development command will ensure your system is configured correctly before creating a genesis block, some keys, a faucet, and then starting a validator on the local machine. fddev will use sudo to make privileged changes to system configuration where needed. If sudo is not available, you may need to run the command as root.

By default fddev will create a new development cluster, if you wish to join this cluster with other validators, you can define [rpc.entrypoints] in the configuration file to point at your first validator and run fddev dev again.
