Price oracles play a crucial role in the blockchain system, enabling smart contracts to be adjusted and executed based on real-world market prices. They typically combine real-world data with smart contracts inside the blockchain through decentralized networks such as Chainlink. Price oracles can provide real-time price  information for blockchain applications in areas such as financial derivatives, exchange-traded products, and asset management, thus achieving a higher degree of automation and intelligence."}]}],"pr":"7d30c7da6bab2592e20858bf5551874227fd27a0013cdeea717c583e0fd17a45"}
