IntroductionBlockchain oracles have become an increasingly important component of decentralized finance (DeFi) protocols, allowing smart contracts to interact with data and external systems beyond the blockchain. Oracles act as intermediaries between off-chain data sources and on-chain smart contracts, providing reliable and timely data to inform smart contract execution. However, the existing oracle systems have limitations, such as the requirement for continuous on-chain data delivery, limi...
