Cardano vs Chainlink FAQ
- What is Cardano?
- Cardano (ADA) is a proof-of-stake blockchain launched in 2017, designed by IOHK with a research-driven approach. Its Ouroboros consensus was peer-reviewed before mainnet, and it has pursued phased upgrades (Byron, Shelley, Goguen, Basho, Voltaire).
- How does Cardano differ from Ethereum?
- Cardano uses an eUTXO model (extended unspent transaction output) rather than Ethereum's account model. It ships upgrades via hard forks coordinated through Haskell-based Plutus smart contracts. Throughput historically lagged peers, though Hydra L2 rollouts aim to close that.
- 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 Cardano and Chainlink compare?
- Cardano (ADA): Research-driven Layer 1. Peer-reviewed Ouroboros consensus, eUTXO model. Launched 2017, runs Ouroboros Proof-of-Stake. Chainlink (LINK): Largest decentralised oracle network. CCIP cross-chain + data feeds. Launched 2017, runs Oracle network (not a blockchain).
