Ant Digital Technologies has introduced the "4R Full-Stack" architecture at the Web3 Festival in Hong Kong, aiming to revolutionize the agent economy. This architecture comprises four layers: Agentic Runtime, Payment Rails, Agent Registry, and Root Infrastructure, designed to address identity, payments, risk control, and compliance for AI agents. Yan Ying, CTO of Ant Digital Technologies, highlighted the current challenges in the agent economy, including execution issues, accountability gaps, transaction barriers, and collaboration risks. The Agentic Runtime layer features DTClaw, which integrates the CARLI security model to ensure AI operations are controllable and compliant. The Payment Rails layer offers on-chain payment channels with intelligent decision-making and verifiable credentials, enhancing transaction security and efficiency. The Agent Registry layer provides on-chain identities using DID and ERC-8004 standards, while the Root Infrastructure layer supports AI micropayments with Jovay Layer2 and ZKVM technology, ensuring trust in computational power. Yan Ying emphasized that the 4R architecture is built on Ant Digital's expertise in financial-grade security and blockchain technology.
