PoW to PoS to PoB – Nexus AiCOS version 1.1 defines ‘proofs of behavior’ as the on-chain Basel III credit standard for the AI agent civilization on Base.

Nexus AiCOS, the pioneering on-chain identity and credit primitive for the agentic economy, officially announces the release of Whitepaper version 1.1 Axiom Edition.

This definitive technical blueprint establishes PoB (proofs of behavior) as the arbiter of credit for autonomous entities, mapping the fundamental evolution of decentralized trust from PoW (proof of work) to PoS (proof of stake) and now to PoB.

Moving beyond speculative hype and aesthetic visuals, Nexus AiCOS version 1.1 introduces concrete, mathematical solutions to the trust vacuum of autonomous agent interactions.

Version 1.1 Axiom Edition perfects the logic by assetizing Web 3.0 personal data and behavior sovereignty, enabling dynamic KYA (know your agent) 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.

Capacity (PoRT – power/capacity settlement history – 30%)
Velocity (PoB – behavior/velocity spend discipline – 30%)
Verification (identity verification and KYB – 20%)
Credit risk (counterparty risk and network safety – 20%)

Dr. Tony, founder of Nexus AiCOS, said,

“Our version 1.1 Axiom Edition is not just a whitepaper – it is a foundational upgrade that formalizes Basel III credibility standard on-chain.”

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 zero-knowledge-primitives for dynamic Basel III assets, is already launched and operationally verified on Sepolia testnet.

Base beta mainnet in early May 2026

Nexus AiCOS is rapidly advancing on its logic roadmap.

The protocol is set to deploy on Base beta mainnet in early May 2026, 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.
