Polkadot Parachains Unleash Customized Blockchains with Shared Security

Polkadot parachains are specialized blockchains connected to the Relay Chain, allowing projects to run customized blockchains while relying on Polkadot for security and finality. According to Kraken, these project-specific chains have their own rules, fees, governance systems, and use cases.

The Parachain model gives developers more control than a typical application running inside another blockchain's execution layer. This structure creates token utility for DOT holders, as parachain growth can increase demand for Polkadot blockspace, security, and cross-chain services.

The Relay Chain coordinates Polkadot's shared security and core scheduling, with validators staking DOT to verify candidate blocks from connected parachains. This setup links parachain operation to the network's staking system and provides economic security through Polkadot's validator set.
