What Is Chainlink?
Chainlink (LINK) is a decentralized oracle network that bridges smart contracts with real-world data. It incentivizes a global network of computers (oracles) to deliver accurate off-chain data to blockchain-based smart contracts.
Key Features:
- Decentralized Oracles: Ensures tamper-proof data feeds for smart contracts.
- LINK Token: Used to pay node operators for data retrieval and processing.
- Wide Adoption: Powers DeFi platforms like Aave and Synthetix.

Founders of Chainlink
Sergey Nazarov (CEO) and Steve Ellis co-founded Chainlink in 2017. Their backgrounds include:
- Nazarov: NYU graduate, founder of SmartContract.com.
- Ellis: Ex-Pivotal Labs engineer, co-founder of Secure Asset Exchange.
How Does Chainlink Work?
Chainlink’s architecture involves three core smart contracts:
- Aggregating Contract: Collects and validates oracle data.
- Order-Matching Contract: Pairs SLAs (Service-Level Agreements) with oracles.
- Reputation Contract: Tracks oracle performance (response time, accuracy).
Process Flow:
- Oracle Selection: Users draft SLAs and deposit LINK.
- Data Reporting: Oracles fetch off-chain data.
- Aggregation: Results are tallied and scored.
