Oracle is a technology that can interact with smart contracts and provide external data for them. In this case, the smart contracts of Chainlink and Band protocols communicate with Oracle nodes in the Chainlink network to obtain reliable and secure price data. These price data can be used to trigger the execution of smart contracts, such as executing arbitrage strategies, monitoring market changes, etc.↵↵Chainlink network is famous for its high decentralization and data security, which connects the real-world data with the blockchain world."}]}],"pr":"0b5446370b37e749ad3f892725c4f3744d132da27f2e1186d3b017ab5d3c2ba3"}
