Parachain Model

Definition

The parachain model describes a specific architectural approach for building scalable and interoperable blockchain networks, notably utilized by Polkadot. In this model, individual blockchains, called parachains, run in parallel and connect to a central relay chain, which provides shared security and facilitates cross-chain communication. Each parachain can have its own specialized functionality and consensus mechanism, while benefiting from the overall network’s security. This design aims to overcome the scalability limitations of monolithic blockchains.
