Exploring the Evolution to Pull Oracles in DeFi"
DeFi protocols play a crucial role in the decentralized finance ecosystem by providing various financial services without the need for traditional intermediaries. Oracles act as bridges between off-chain data and on-chain smart contracts, enabling DeFi protocols to access real-world information. When it comes to oracles, there are two main types: Push oracles and Pull oracles. Push oracles work by having specific operators update the on-chain price at regular intervals, regardless of whether the data is being used or not. On the other hand, pull oracles update the on-chain price only when requested by users, allowing for more efficient and cost-effective data updates. One key advantage of pull oracles, such as Pyth Network, is the decentralized nature of data updates. In pull oracles, anyone can permissionlessly update the on-chain price, promoting transparency and reducing reliance on centralized entities. This decentralized approach enhances the security and reliability of the price
