In the era of rapid iteration of blockchain technology, the authenticity and availability of on-chain data have become the key constraints for the entire industry's upgrade. The new generation of decentralized oracle represented by $AT is reshaping this situation.

The core issue is actually quite straightforward: Blockchain networks need to interface with real-world data, but centralized data sources can easily become single points of failure and security vulnerabilities. These oracle machine solutions build a trusted on-chain data transmission system through multi-node redundant verification and cryptographic algorithm mechanisms.

From a technical perspective, the highlights of this type of solution are as follows: first, the consensus mechanism of distributed nodes reduces the risk of data tampering; second, the real-time data aggregation capability supports high-frequency trading scenarios; third, cross-chain data interoperability paves the way for ecological connectivity.

On the application side, DeFi protocols rely on accurate price data to execute liquidations and transactions, the NFT market requires on-chain data to verify asset attributes, and the metaverse ecosystem needs trustworthy identity and asset data. The common demand in these scenarios is the driving force behind the continuous improvement of oracle infrastructure. The question now is not whether it is needed, but how to find a balance between performance and security.
