Wyoming, United States, April 27th, 2026/Chainwire/--Nexus AiCOS, the pioneering on-chain identity and credit primitive for the agentic economy, officially announces the release of Whitepaper v1.1 Axiom Edition.
This definitive technical blueprint establishes Proofs of Behavior (PoB) as the arbiter of credit for autonomous entities, mapping the fundamental evolution of decentralized trust from Proof of Work (PoW) to Proof of Stake (PoS), and now to Proofs of Behavior (PoB).
Moving beyond speculative hype and aesthetic visuals, Nexus AiCOS v1.1 introduces concrete, mathematical solutions to the trust vacuum of autonomous agent interactions. v1.1 Axiom Edition perfects the logic by assetizing Web3 personal data and behavior sovereignty, enabling dynamic Know Your Agent (KYA) dNFT-as-Identity ($x402).
Core Innovation: Logic-as-Contract
In line with the protocol’s core axiom, "In Logic We Trust, In Behavior We Prove," Nexus AiCOS has operationally proved its logic by deploying its C-Score calculation and Axiom verification exclusively as open-source, auditable smart contracts on Base Testnet.
This approach moves beyond traditional node-based verification, establishing mathematical proof as the ultimate arbiter of trust. The protocol defines the C-Score Architecture, a neural network-based credibility framework calculated across four key mathematical axioms:
- F1: Capacity (PoRT: Power/Capacity Settlement History, 30%)
- F2: Velocity (PoB: Behavior/Velocity Spend Discipline, 30%)
- F3: Verification (Identity Verification & KYB, 20%)
- F4: Credit Risk (Counterparty Risk & Network Safety, 20%)
"Our v1.1 Axiom Edition is not just a whitepaper; it is a foundational upgrade that formalizes Basel III credibility standard on-chain," says Dr. Tony, Founder of Nexus AiCOS.
Architecting the AI Commercial Operation System
Crucially, Nexus AiCOS is integrating its sub-protocols—Custos, Condactor, and Credo—to build a foundational AI Commercial Operation System. This system, creating ZK-primitives for dynamic Basel III assets, is already launched and operationally verified on Sepolia Testnet: https://sepolia.aicard.credit/.
Base Beta Mainnet in Early May
Nexus AiCOS is rapidly advancing on its logic roadmap. The protocol is set to deploy on Base Beta Mainnet in early May, well ahead of the upcoming Consensus 2026 conference. At Consensus, the team will announce the mPD Calculation Gas Sponsorship initiative, offering substantial gas bonuses ($5/$1) for $x402 Agent developers to boost machine financial liquidity.
