Ethereum vs Chainlink FAQ
- What is Ethereum?
- Ethereum (ETH) is a programmable blockchain launched in 2015. It lets developers deploy smart contracts — self-executing programs that power DeFi, NFTs, DAOs, and most on-chain applications. ETH is the native asset used to pay for transactions ("gas").
- How is Ethereum different from Bitcoin?
- Bitcoin is optimised for being sound money and a settlement layer; Ethereum is optimised for programmability. Ethereum switched to proof-of-stake in 2022 (The Merge), so it has no miners — validators stake ETH to secure the network instead.
- 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 Ethereum and Chainlink compare?
- Ethereum (ETH): Programmable Layer 1. Smart contracts, DeFi, NFTs. Proof-of-stake since 2022. Launched 2015, runs Proof-of-Stake. Chainlink (LINK): Largest decentralised oracle network. CCIP cross-chain + data feeds. Launched 2017, runs Oracle network (not a blockchain).
