Step-by-step process of building Polkadot node

Before going into the node-building process, ensure that you have the following prerequisites -


Hardware Requirements - A dedicated server or a virtual private server (VPS) with sufficient computing power and storage

Stable internet connection with ample bandwidth.



Software Requirements - A recent version of Linux (Ubuntu, CentOS, or similar).

Basic command-line knowledge.

• Step 1: Install Dependencies

Start by updating your system's package list:


'sudo apt update && sudo apt upgrade -y'       ---- copy this code


Next, install necessary dependencies -


'sudo apt install -y git clang cmake pkg-config libssl-dev'  ---- copy this code

• Step 2: Install Rust

Polkadot is built using the Rust programming language. 

Install Rust using the official script:


'curl https://sh.rustup.rs -sSf | sh source $HOME/.cargo/env'  ---- copy this code

• Step 3: Clone the Polkadot Repository

Clone the Polkadot GitHub repository to your machine:


'git clone https://github.com/paritytech/polkadot.git'    ---- copy this code



Navigate to the Polkadot directory:

'cd polkadot'     ---- copy this code

• Step 4: Build Polkadot

Build Polkadot using the following commands:


'cargo build --release'   ---- copy this code



This process may take some time as it downloads and compiles the necessary dependencies.

• Step 5: Configure Your Node

Create a configuration file for your node. 

Copy the example template:


'cp node-template/res/polkadot/node.toml ./node.toml'  ---- copy this code


Edit the 'node.toml' file to customize your node's settings, such as the chain type, name, and telemetry endpoint.

• Step 6: Launch Your Polkadot Node

Run your Polkadot node with the following command:


'./target/release/polkadot --name <YourNodeName> --base-path /path/to/your/node/data'   ---- copy this code


Replace '<YourNodeName>' with your desired node name. 

The '--base-path' option specifies the directory where your node's data will be stored.

• Step 7: Monitor Your Node

To monitor your node's performance, you can use tools like Grafana and Prometheus. 

Polkadot provides a telemetry system that you can enable in your configuration file.
