<h2 class="wp-block-heading" id="h-polkadot-and-rust">Polkadot and Rust</h2>
<h3 class="wp-block-heading" id="h-introduction-to-polkadot">Introduction to Polkadot</h3>
<a href="https://markets.coinpedia.org/polkadot-new/" target="_blank" rel="noopener noreferrer nofollow">Polkadot</a>, developed by Gavin Wood—co-founder of <a href="https://markets.coinpedia.org/ethereum/" target="_blank" rel="noopener noreferrer nofollow">Ethereum</a>—is a groundbreaking platform featuring its native cryptocurrency, DOT. Like Solana, Polkadot utilizes the <a href="https://coinpedia.org/glossary/pos/" target="_blank" rel="noopener noreferrer nofollow">Proof-of-Stake</a> (PoS) mechanism. It’s built on the Substrate framework, crafted in Rust, highlighting Rust’s critical role in Polkadot’s ecosystem.
Polkadot enables seamless cross-chain transactions and messaging without the need for intermediaries. At its core is the relay chain, responsible for validating data, achieving consensus, and managing transactions.

 <li>&nbsp;Then Install Rust</li>
 <li>Install all the additional dependencies&nbsp;</li>
 <li>Setup Polkadot.js&nbsp; and create Node</li>
 <li>Configure the environment and launch the project in IDE.</li>
</ol>
<ul>
 <li>Basic tutorial on how to write and deploy simple parachain:</li>
</ul>
// Sample Rust parachain for Polkadot
use substrate_substrate_runtime::{
&nbsp;&nbsp;&nbsp;&nbsp;GenesisConfig, SubstrateModule,
};
pub struct MyParachain;
impl SubstrateModule for MyParachain {
&nbsp;&nbsp;&nbsp;&nbsp;fn genesis_config() -&gt; GenesisConfig {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;GenesisConfig::default()
&nbsp;&nbsp;&nbsp;&nbsp;}
}
The above code snippet is an example of parachain code. The first part is the imports, and then there is the defined struct MyParachain, which denotes a custom parachain.
