Smart contracts rely on external data to execute their logic and perform their intended functions. However, getting reliable and secure data from off-chain sources can be challenging. This is where Chainlink comes in. Chainlink is a decentralized oracle network that provides reliable and tamper-proof data to smart contracts on the blockchain. It connects smart contracts with off-chain data sources in a decentralized manner, ensuring that data is accurate, trustworthy, and secure. By using Chainlink, smart contracts can become more powerful and versatile, with the ability to perform more complex functions and interact with real-world data in a secure and decentralized way.
