Polkadot (DOT) perpetual market

Polkadot is a proof-of-stake network launched in 2020 by Ethereum co-founder Gavin Wood and the Web3 Foundation, built to let many specialized blockchains interoperate and share security. Its native token, DOT, is used for staking, governance and bonding. Rather than one chain running every application, Polkadot has a central relay chain that provides shared security to parachains, independent chains that plug in and can pass messages to one another, an architecture aimed at a scalable multi-chain internet. Projects historically secured parachain slots through competitive auctions, later replaced by a more flexible coretime model. Polkadot's technology stack, Substrate, became a widely used framework for building custom blockchains across the industry. DOT holders govern the network directly through on-chain voting, and Wood's Web3 branding helped popularize the broader idea of a decentralized web.
