chainlink

Chainlink is a decentralized oracle network founded by Sergey Nazarov and Steve Ellis, connecting blockchains to real-world data. It enables smart contracts to access reliable data, including weather data, market prices, or sports results, which blockchain alone cannot fetch. The platform is designed to ease the flow of tamper-proof data from off-chain sources to on-chain smart contracts.

Key Features:

• The native LINK token is used to pay the node operators to retrieve data and perform off-chain operations.
  
• Used in various sectors such as decentralized finance, gaming, insurance, and supply chain management.
  
• Nodes of Chainlink check and validate data from multiple sources before delivering it to smart contracts.
  
• Accurate price feeds for the assets to help users make informed decisions.
