About Polkadot
Polkadot is a multi-chain network built so that independent blockchains can exchange messages and share security. Rather than hosting applications directly, it coordinates a set of specialized chains that plug into a central relay chain. DOT is the native asset, used for staking, governance and bonding new chains onto the network.
How Polkadot Works
A central relay chain provides consensus and finality for every chain connected to it. Those connected chains, called parachains, run their own logic and can be optimized for a specific purpose while inheriting the relay chain's security. A cross-consensus messaging format lets them pass data and assets between one another without a trusted bridge operator.
The History of Polkadot
Polkadot was proposed in a 2016 white paper by Gavin Wood, a co-founder and former chief technology officer of Ethereum, and developed by Parity Technologies with backing from the Web3 Foundation. The relay chain went live in 2020, parachains were auctioned from late 2021, and the network has since moved towards a more flexible model for allocating blockspace.
What DOT Is Used For
DOT secures the network through nominated proof-of-stake, where holders back validators and share in rewards. It carries governance rights over protocol upgrades and treasury spending, which execute on-chain without a hard fork. DOT is also bonded to secure a slot for a parachain, tying the asset directly to demand for space on the network.
