# [Firedancer](https://jumpcrypto.com/firedancer/) 🔥💃 Firedancer is a new validator client for Solana. * **Fast** Designed from the ground up to be *fast*. The concurrency model draws from experience in 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](https://docs.firedancer.io/) ## Releases If you are an operator looking to run the validator, see the [Releases Guide](https://docs.firedancer.io/guide/getting-started.html#releases) in the documentation. ## Developing Firedancer currently only supports Linux and requires a relatively new kernel, at least v4.18 to build. ```console $ git clone https://github.com/firedancer-io/firedancer.git $ cd firedancer $ ./deps.sh # install system dependencies $ make -j # build `firedancer-dev` $ ./build/firedancer-dev --testnet # join testnet ``` `firedancer-dev` (without args) configures your system for validator operation and creates a new local development cluster. First it creates a genesis block, some keys, a faucet, and then it starts a validator on the local machine. `firedancer-dev` 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. If you wish to join this cluster with other validators, you can define `[gossip.entrypoints]` in the configuration file to point at your first validator and join with `firedancer-dev run`. ## License Firedancer is available under the [Apache 2 license](https://www.apache.org/licenses/LICENSE-2.0). Firedancer also includes external libraries that are available under a variety of licenses. See [LICENSE](LICENSE) for the full license text.
