What is Chainlink?

Chainlink is a decentralized service that connects various data in the real world with smart contracts on the Ethereum blockchain.

A smart contract is a mechanism on the blockchain that automatically executes a contract when certain conditions are met, but there are many cases where the conditions rely on real-world data.

Chainlink aims to create an environment where all smart contracts can securely use the provided data by introducing a mechanism that incentivizes data providers who provide highly reliable real-world data.
