APRO is building a decentralized oracle infrastructure designed to deliver reliable, verifiable, and cross-chain data for Web3 applications. Its architecture is structured into multiple layers, each responsible for ensuring data accuracy, security, and usability across different blockchain ecosystems.
Data Providers Layer
At the foundation, APRO integrates a wide range of trusted data providers, including centralized exchanges, decentralized exchanges, CoinMarketCap, Random.org, Nasdaq, and CME Group. These sources supply diverse and high-quality data inputs.
Using Large Language Models (LLMs), nodes in this layer are able to analyze unstructured data such as PDF documents, images, and videos, and convert it into structured data that can be safely fed on-chain.
Data Feed Layer
Data collected from providers is aggregated and processed in the Data Feed layer. This layer is built on an Oracle Chain powered by Babylon, which incentivizes data providers to deliver accurate and timely information.
The data feeds operate through the Cosmos State Machine, with final results aggregated using Vote Extensions, ensuring consensus-driven accuracy.
Verdict Layer
Batched and aggregated data is then passed to the Verdict layer for validation. This layer uses AVS systems powered by Satlayer or Chakra to verify historical data submissions.
If conflicts or malicious behavior are detected within the Data Feed layer, the system triggers a slashing mechanism, reinforcing network security and accountability.
API and Contracts Layer
Validated oracle data is made accessible through standardized APIs and smart contracts. Feed Contracts and Consumer Contracts manage both push and pull interactions with decentralized applications.
Beyond EVM compatibility, APRO also supports Bitcoin DLC oracle signature services and CKB Price Feed Cells, extending oracle functionality to UTXO-based ecosystems.
Application Layer
At the top layer, a wide range of applications integrate with APRO’s oracle system, including DeFi, GameFi, NFTs, OmniFi, and Real-World Asset (RWA) platforms. These applications rely on APRO’s secure and accurate data to enable advanced on-chain use cases.
By combining AI-driven data processing, layered validation, and cross-chain support, APRO is positioning itself as a next-generation oracle infrastructure for the evolving Web3 ecosystem.
