Article Introduction：The indispensable thing to connect the digital world of blockchain with the real world is blockchain oracles. They are like the eyes and ears of blockchain, ensuring the ability to interact with the outside world. Blockchain technology is not only a A static ledger, but a dynamic system that affects and reacts to the real world. So what exactly does this blockchain oracle mean? Simply put, it is a mechanism that connects the blockchain and external data, allowing smart contracts to obtain and use information that occurs outside the blockchain. The editor below will tell you in detail. What does blockchain oracle mean? A blockchain oracle is a third-party service that provides external data to the blockchain. They act as a bridge between on-chain and off-chain systems. Although the closed nature of blockchain ensures security and trustworthiness, many applications

Article Introduction：The Oracle Protocol acts as an intermediary between decentralized networks and external data sources, connecting on-chain and off-chain data in a secure and scalable way. This includes WebAPIs, databases, connected device sensors, real-time data feeds, and even other blockchain networks. As blockchain applications become more complex, this off-chain data becomes increasingly important for the development of new use cases (such as the recently popular “machine learning”). This article will take an in-depth look at three key oracle protocols, Chainlink, Pyth, and Flare. Although Chainlink currently leads the market, it has limitations in latency and high throughput; while Pyth focuses on financial institutions and lacks in universality. It is worth noting that the "dark horse" prophecy
