Polkadot vs Chainlink FAQ
- What is Polkadot?
- Polkadot (DOT) is a sharded multi-chain network launched in 2020 by Gavin Wood (Ethereum co-founder, Parity CEO). Its Relay Chain provides shared security for connected parachains, each of which can specialise its own logic and governance.
- What are Polkadot parachains?
- Parachains are application-specific L1-like chains that lease a slot on Polkadot for a fixed term by bonding DOT. Examples: Acala (DeFi), Moonbeam (EVM compatibility), Hydration (liquidity). Recent Polkadot 2.0 moves toward "coretime" — renting blockspace per block.
- What is Chainlink?
- Chainlink (LINK) is the largest decentralised oracle network, launched in 2017. Oracles feed real-world data (prices, weather, match scores, cross-chain state) into smart contracts, since blockchains cannot fetch external data natively.
- What is LINK used for?
- LINK pays node operators for oracle reports, secures stake on nodes via Chainlink Staking, and is the unit of account for Chainlink Services (CCIP cross-chain, Proof of Reserve, VRF randomness, and Data Feeds).
- How do Polkadot and Chainlink compare?
- Polkadot (DOT): Sharded multi-chain network. Parachains share relay-chain security. Launched 2020, runs Nominated Proof-of-Stake. Chainlink (LINK): Largest decentralised oracle network. CCIP cross-chain + data feeds. Launched 2017, runs Oracle network (not a blockchain).
