About Chainlink (LINK)
Chainlink is a cryptocurrency and technology platform that enables non-blockchain enterprises to securely connect with blockchain platforms. Chainlink is middleware that connects blockchain-based smart contracts with external data, such as baseball scores or stock prices.
Smart contracts are programmatic code (if x event occurs, execute y action) that operate on a blockchain network. However, due to the security model of blockchain networks, smart contracts are isolated from the external world and cannot natively connect to off-chain systems.
To overcome this problem, an additional piece of infrastructure is required known as an “oracle” which relays data from the real world onto blockchain networks, where it can be consumed by smart contracts.
The Chainlink Network addresses this issue through Decentralized Oracle Networks (DONs) that consist of a network of independent oracle node operators that fetch, aggregate, validate, and deliver real-world data on-chain. Each oracle node can specialize in providing different decentralized services on the behalf of smart contracts.
