Implementation of a https://polkadot.network node in Rust based on the Substrate framework.
NOTE: In 2018, we split our implementation of "Polkadot" from its development framework "Substrate". See the Substrate repo for git history prior to 2018.
This repo contains runtimes for the Polkadot, Kusama, and Westend networks. The README provides
information about installing the
polkadot binary and developing on the codebase. For more
specific guides, like how to be a validator, see the
If you just wish to run a Polkadot node without compiling it yourself, you may either run the latest binary from our releases page, or install Polkadot from one of our package repositories.
Installation from the debian or rpm repositories will create a
service that can be used to run a Polkadot node. This is disabled by default,
and can be started by running
systemctl start polkadot on demand (use
systemctl enable polkadot to make it auto-start after reboot). By default, it
will run as the
polkadot user. Command-line flags passed to the binary can
be customised by editing
/etc/default/polkadot. This file will not be
overwritten on updating polkadot. You may also just run the node directly from
Debian-based (Debian, Ubuntu)
Currently supports Debian 10 (Buster) and Ubuntu 20.04 (Focal), and
derivatives. Run the following commands as the

RPM-based (Fedora, CentOS)
Currently supports Fedora 32 and CentOS 8, and derivatives.
# Install dnf-plugins-core (This might already be installed) dnf install dnf-plugins-core # Add the repository and enable it dnf config-manager --add-repo https://releases.parity.io/rpm/polkadot.repo dnf config-manager --set-enabled polkadot # Install polkadot (You may have to confirm the import of the GPG key, which # should have the following fingerprint: 9D4B2B6EB8F97156D19669A9FF0812D491B96798) dnf install polkadot
Install via Cargo
If you want to install Polkadot in your PATH, you can do so with with:
cargo install --git https://github.com/paritytech/polkadot --tag <version> polkadot --locked
Build from Source
If you'd like to build from source, first install Rust. You may need to add Cargo's bin directory to your PATH environment variable. Restarting your computer will do this for you automatically.
curl https://sh.rustup.rs -sSf | sh
If you already have Rust installed, make sure you're using the latest version by running:
Once done, finish installing the support software:
sudo apt install build-essential git clang libclang-dev pkg-config libssl-dev
Build the client by cloning this repository and running the following commands from the root directory of the repo:
git checkout <latest tagged release> ./scripts/init.sh cargo build --release
Note that compilation is a memory intensive process. We recommend having 4 GiB of phyiscal RAM or swap available (keep in mind that if a build hits swap it tends to be very slow).
This repo supports runtimes for Polkadot, Kusama, and Westend.
Connect to Polkadot Mainnet
Connect to the global Polkadot Mainnet network by running:
