Polkadot is a next-generation blockchain protocol that enables scalability, interoperability, and governance of multiple blockchains. Its unique consensus mechanism allows it to scale horizontally, meaning that it can support an unlimited number of transactions without compromising on security or decentralization. The system's governance model allows for on-chain upgrades and forks without resulting in chain splits or hard forks, while still under development. Polkadots is a decentralized network of blockchains that enables cross-chain transfers of data and value. It is an open-source project created by the Web3 Foundation.
