Polkadot dot
What is Polkadot?
Polkadot is a Layer-0, multi-chain blockchain protocol designed to let independent blockchains communicate and share security. Its Relay Chain provides consensus and security, while parachains process their own state transitions. The native asset is DOT.
What problem does Polkadot solve?
Polkadot addresses fragmentation and bootstrapping problems of multi-chain ecosystems. Standalone chains must recruit their own validator set; Polkadot lets connected chains use shared security and communicate through XCM.
How does Polkadot work?
The Relay Chain coordinates consensus and shared security. Parachain collators propose blocks; validators check availability and validity. XCM carries messages between parachains. Polkadot uses Nominated Proof of Stake (NPoS). DOT is used for governance, staking, fees, and coretime purchases.
