what's Quantu?

Quantu is an AI infrastructure project on the Solana blockchain, specializing in tools for the agent economy powered by the 8004 standard. Their flagship product is the Agent Registry, a native Solana implementation of the ERC-8004 protocol. AI agents are registered as Metaplex Core NFTs, enabling on-chain identity portability. Reputation is managed through the ATOM engine, a Sybil-resistant system with tiered trust levels based on verifiable feedback, tags for performance metrics, and SEAL v1 for integrity. Developers interact via the open-source 8004-solana TypeScript SDK (npm install 8004-solana), supporting registration, feedback submission, reputation queries, and wallet operations for trustless agent discovery, collaboration, and transactions. Quantu also develops DeFi-8004, an agent-optimized DeFi protocol with staking rewards; 8004market, a cross-chain marketplace for trading 8004 agent assets; and on-chain AI models, including compact neural networks running directly on Solana for practical inference. The $QX utility token unlocks staking for revenue shares, discounted on-chain AI inference, and priority ecosystem access.
