Polkadot blockchain is a next-generation blockchain platform enabling multiple blockchains (parachains) to operate together securely and seamlessly. Developed by Web3 Foundation, Polkadot facilitates cross-chain interoperability, scalability, and shared security through its relay chain. It supports decentralized applications, token transfers, and governance across networks. Polkadot’s native token, DOT, is used for staking, governance, and bonding parachains. The platform empowers developers to build custom blockchains with specific features while benefiting from Polkadot’s ecosystem. It’s ideal for projects seeking modularity, scalability, and multi-chain compatibility.
