After using the APRO decentralized oracle for a period of time, it indeed solved many development pain points. The most intuitive feeling is its data delivery flexibility—push and pull modes can be switched according to scenarios. For price-related applications, use the push mode, where the system automatically pushes the latest data onto the chain with excellent response speed; for on-demand query services, the pull mode comes in handy, triggering calls whenever needed, fully autonomous and controllable.

More importantly, data quality assurance. After using its AI verification mechanism, it can automatically identify abnormal data and noise information, which is especially important in DeFi applications. I previously experienced issues when developing lending protocols—an abnormal market fluctuation caused price data errors, almost leading to pricing chaos. After integrating APRO, cross-verification of multi-source data can basically preempt similar risks.

Another great feature is verifiable randomness. I used it in developing an NFT lottery system; the random numbers generated based on cryptographic algorithms are truly tamper-proof and transparently verifiable, significantly increasing users' trust in the lottery results. The dual-layer network architecture design is also quite thoughtful, ensuring security while maintaining operational efficiency.
