$BTC Polkadot (DOT) is a multi-chain protocol aimed at enabling interoperability between blockchains, allowing different blockchains to transfer messages and value without the need for trust. Gavin Wood, one of the co-founders of Ethereum, created Polkadot, which features a central relay chain that provides security and coordination for connected blockchains, which are independent blockchains with their own use cases and governance mechanisms.

DOT is the native token used for governance, staking (securing the network and participating in consensus), and linking (connecting new blockchains to the relay chain). The architecture of Polkadot is designed to be highly scalable and flexible, facilitating innovation by allowing developers to build specialized blockchains that can communicate with each other, fostering a diverse and interconnected ecosystem for Web3 technology.
