NEUS Network
Portable Trust Infrastructure for Humans and AI.
Portable Proof carries verified identity, authority, and action evidence across apps, agents, and networks.
Run a check once. Save the result. Reuse it where accepted.

Why NEUS
People and products repeat the same identity, ownership, risk, and permission work in every new system. NEUS saves supported results as Portable Proofs so a connected product can evaluate them under its own rules.
Use one proof model for profiles, product gates, paid access, and AI agents. A proof is reusable only when the receiving product accepts its source and the proof still meets its policy.
NEUS does not replace authentication, specialist verification providers, application policy, payment processing, agent runtimes, or complete audit logs. The integration must call the check and enforce the result on the protected path.
| Need | What you get with NEUS |
|---|---|
| Reuse a completed check | A proof with source, status, scope, and expiry |
| Keep proofs in one profile | Private-by-default proof management and selective sharing |
| Add verification to an app | Hosted sign-in, API, SDK, and React widgets |
| Sell protected access | Published checks, price, hosted checkout, and a server confirmation |
| Set limits on an AI agent | Owner, optional spend account, allowed and denied actions, expiry, and revocation |

Then ask:
Reuse what I already have. Before a sensitive action, check my current proofs.
NEUS answers Passed, Action needed, or Blocked. Full steps: MCP setup.

Open standard
NEUS is a reference implementation of CAIP-380 (Portable Proof) (PR), a ChainAgnostic standard at Draft status. Wallet-signed request envelopes use a deterministic SHAKE-256 hash (qHash), CAIP-2 chain context, and CAIP-10 / did:pkh identities. The hash, DID binding, and signature can be checked without NEUS. Verifier outcomes remain part of the NEUS portable proof. The envelope works with any CAIP-2 namespace and that chain’s native signing scheme. See Standards & interoperability, the offline examples, the CAIP-380 docs, and the Technical Whitepaper.
