Polkadot is a next-generation blockchain protocol that aims to enable different blockchains to interoperate and share information securely. Developed by the Web3 Foundation and created by Ethereum co-founder Gavin Wood, Polkadot's unique multi-chain framework enhances scalability and flexibility. Its relay chain allows for parachains to connect and communicate, fostering a more interconnected and efficient ecosystem. This innovative approach addresses some of the limitations of traditional blockchains, making Polkadot a significant player in the evolution of decentralized technologies.
