Polkadot is an open-source protocol founded by the Web3 Foundation, aiming to enable a completely decentralized web where users are in control. Polkadot can upgrade without hard forks to integrate new features or fix bugs. It enables cross-blockchain transfers of any type of data or asset, not just tokens. Besides, Polkadot's novel data availability and validity scheme allows chains to interact with each other in a meaningful way. It has a sophisticated governance where all stakeholders have a voice, ensuring that Polkadot’s development reflects the values of the community and avoids stagnation.
