Nexus AiCOS released Whitepaper v1.1 - Axiom Edition, positioning Proofs of Behavior (PoB) as the on-chain credit standard for autonomous entities operating in the agentic economy. The protocol describes the update as a technical refinement that moves decentralized trust forward from Proof of Work to Proof of Stake and now to Proofs of Behavior.
According to the Axiom Edition, the release provides concrete mathematical mechanisms intended to address trust challenges among autonomous agents. The paper frames its contribution around assetizing Web3 personal data and defending behavior sovereignty, enabling a dynamic Know Your Agent capability realized through a dNFT-based identity token referenced as $x402.
The protocol characterizes its central innovation as "Logic-as-Contract." Nexus AiCOS reports that its C-Score calculation and Axiom verification are implemented as open-source, auditable smart contracts deployed on Base Testnet. The project emphasizes on-chain mathematical proof instead of traditional node-based verification as the basis for machine credibility.
The v1.1 publication defines a C-Score Architecture calculated by a neural network-based credibility framework across four mathematical axioms with explicit weighting:
- 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.
Beyond the C-Score, the protocol is integrating a set of sub-protocols - Custos, Condactor, and Credo - into what it describes as an AI Commercial Operation System. These components are said to produce zero-knowledge primitives for "dynamic Basel III assets," and Nexus AiCOS reports that these elements are launched and operationally verified on Sepolia Testnet at https://sepolia.aicard.credit/.
As part of its roadmap, Nexus AiCOS has indicated that it will deploy to Base Beta Mainnet in early May, ahead of the Consensus 2026 conference. The team has planned to make a related announcement at Consensus: the mPD Calculation Gas Sponsorship initiative. That initiative is described as offering gas bonuses - listed as $5/$1 - for $x402 Agent developers intended to bolster machine financial liquidity.
The Axiom Edition package includes technical documentation, a full PDF of the whitepaper, and visual materials for the CX-ID dNFT Axioms, all accessible through the project's primary website at https://nexusaicos.ai/. The release also includes a link to a demonstration video on YouTube: https://www.youtube.com/watch?v=dVZUPjkw_I4.
The project materials describe Nexus AiCOS as a foundational on-chain credit and identity layer for autonomous entities, asserting that mathematical proof via ZK-primitives and a dynamic KYA dNFT ($x402) will serve as the arbiter of machine credibility. The release invites builders to "Build the next generation of credit-as-capital Agents" and provides pathways to testnet and beta mainnet access:
