About Polkadot (DOT/USD)
Polkadot is a protocol designed to let independent blockchains operate together under shared security. It was proposed by Gavin Wood, a co-founder of Ethereum and the author of its original technical specification, and developed with the Web3 Foundation. The network launched in 2020.
Its central idea is a division of labour. A central chain, the relay chain, provides consensus and security. Separate chains connect to it and inherit that security rather than having to bootstrap their own validator set. This matters because a small independent blockchain is cheap to attack: security has to be paid for, and a young network cannot pay for much. Connecting to a larger pool of validators is a way around that problem.
Polkadot uses a nominated proof-of-stake system, in which holders back validators with their own stake and share in rewards and penalties. DOT, the network’s token, is used for staking, for governance, and to acquire the connection slots that let a chain join the network. Kusama, a separate network with the same codebase, runs as a deliberately less cautious proving ground for changes before they reach Polkadot.
What Moves Polkadot?
Connected chains and slot demand
Polkadot’s value proposition depends on chains actually wanting to connect. Demand for slots, and the amount of DOT committed to secure them, are direct measures of whether the model is being used.
Staking participation
A large share of supply is typically staked, which removes it from immediate circulation. Changes in staking rewards or in unbonding terms affect how much is readily tradeable.
Governance decisions
Polkadot’s governance is on-chain, and treasury spending, protocol parameters and upgrades are decided by token holders. Outcomes here change the network’s direction without requiring a fork.
Competition among smart-contract platforms
Polkadot competes for developers with other platforms pursuing interoperability and scaling by different routes. Broad crypto direction also matters: the correlations shown on this page are measured from our own daily closes.
