DOT is het native asset dat wordt gebruikt voor staking, governance, overdraagbare waarde en coretime-gerelateerde netwerkfuncties. Validators beveiligen de relay chain onder Nominated Proof of Stake, collators assembleren parachain-kandidaten, en XCM definieert berichten tussen consensus-systemen. BABE ondersteunt blokproductie terwijl GRANDPA finaliteit biedt, zodat parachain-uitvoering en relay-chain-beveiliging verschillende rollen hebben. Gebruik deze pagina om Polkadot, Polkadot Hub en individuele parachains te onderscheiden, te begrijpen waar DOT vereist is, en veiligere staking- of cross-chain-acties voor te
