Про Polkadot

Polkadot is a cross-chain protocol designed to connect and secure different blockchains. It provides interconnectivity and interoperability between them, enabling independent chains to securely exchange messages and perform transactions without relying on a trusted third-party. This allows for cross-chain transfers of data or assets between different blockchains, as well as the development of cross-chain DApps (decentralized applications) using the Polkadot Network. The Web3 Foundation is responsible for building Polkadot.
