Polkadot is an open-source platform for Web3, a decentralized, user-owned internet. Polkadot provides a scalable, interoperable and secure protocol for the next wave of web applications. These features are ensured by a multi-chain design featuring a relay chain which unites a network of heterogenous blockchains called parachains and parathreads. Through bridges these blockchains can even connect to external networks such as Bitcoin and Ethereum for true cross-chain interoperability.

Parachains are customizable using the Substrate framework, meaning that they can specialize for different use caes and control their own governance. Further, the multi-chain architecture allows for parallel processing of transactions, creating a highly scalable system.

Other features of Polkadot include forkless network upgrades, user-driven governance and a shared security budget across chains.

Benefits of running this node
Running your own node on any Substrate-based chain, like Polkadot, Acala or a custom implementation provides you with accurate data. A full node allows developers to be independent from third-party providers.
