Polkadot DOT.X

Polkadot is a blockchain network that allows users to launch and operate their own blockchains, called parachains, on top of the main Polkadot blockchain, called the relay chain. The relay chain does not support smart contracts, but parachains can. This allows for a growing ecosystem of blockchains with varying features and secure transactions, all using the resources of the relay chain. Polkadot also includes bridges to allow interaction with other blockchains, such as token swaps without a centralized exchange. The native cryptocurrency, DOT, serves as the governance token, allowing holders to stake and vote on network upgrades and participate in governance. Staking DOT also yields returns and can be bonded to secure a parachain slot. The project was founded by Ethereum co-founder Gavin Wood and is overseen by the non-profit Web3 Foundation, which maintains the open-source code and allocates funds for development.
