Wu said that the oracle Pyth Network announced the launch of Oracle Integrity Staking (OIS), an upgraded version of Pyth, which aims to improve the reliability of data sources and the security of the DeFi ecosystem. OIS encourages publishers and PYTH holders to participate in staking and ensure the security of the oracle network by introducing on-chain staking rewards and penalty mechanisms. Publishers can be rewarded by providing high-quality data, and if the data is wrong, they will be punished. In addition, PYTH holders can stake and delegate to publishers to enhance their returns. Pyth DAO will be responsible for overseeing key updates and parameters of OIS.
