Nexus AiCOS has released Whitepaper v1.1 Axiom Edition, detailing its on-chain identity and credit system for an agentic economy. It uses Proofs of Behavior (PoB) to establish trust for autonomous entities, moving beyond Proof of Work and Proof of Stake. The system assetizes Web3 data for dynamic Know Your Agent (KYA) using dNFT-as-Identity ($x402). The protocol's core is "In Logic We Trust, In Behavior We Prove," verified by open-source smart contracts on Base Testnet. The C-Score Architecture calculates credibility across Capacity, Velocity, Verification, and Credit Risk. Nexus AiCOS is building an AI Commercial Operation System integrating Custos, Condactor, and Credo. This system is live on Sepolia Testnet and will launch on Base Beta Mainnet in early May. The team will announce a gas bonus initiative for $x402 Agent developers at Consensus 2026. Users can find the full whitepaper and more information on the Nexus AiCOS website. Nexus AiCOS aims to be the foundational credit and identity layer for autonomous entities.
