GoAnon Verify · Private age proof

Prove your age. Not your identity.

GoAnon Verify is a private-alpha browser extension and website proof protocol for privacy-preserving age eligibility checks. It is being built so cooperating websites can verify eligibility without receiving your raw ID document, exact birthdate, face scan, wallet identifier, or browsing trail.

0.2.0-alpha Browser extension Backend replay demo OpenEUDI evaluation EUDI scaffold disabled

GoAnon Verify is not a public browser-store release and is not legal or production age verification yet. Demo/local-test proofs are development-only and are rejected by production verifiers by default.

What websites should learn

The goal is simple: a website should learn whether you meet an age requirement, not who you are.

Shared

Only what is necessary

Age eligibility, for example over 18 = yes.
A short-lived proof envelope or wallet presentation.
A single-use challenge bound to the requesting website.
A privacy label explaining the proof method.

Not shared

No identity disclosure

Name.
Exact birthdate.
ID document or passport scan.
Face scan or biometric data.
Stable wallet identifier.
Browsing activity to an issuer, government, GoAnon Verify server, or other GoAnon ecosystem server.

Current alpha status

GoAnon Verify is being built carefully because age verification can either protect dignity or become surveillance infrastructure.

Private alpha

Browser extension

Chromium and Firefox builds exist for private alpha testing. Public store links will appear here only when GoAnon Verify is ready for broader testing.

Chrome coming soon Firefox coming soon

Replay protection

Backend verifier demo

The alpha now includes a production-style relying-party backend demo with single-use challenges, challenge-hash storage, audience binding, expiry checks, and replay rejection.

challenge bound audience bound replay rejected

Verifier hardening

Production safety defaults

Production verifiers reject demo proofs by default, require real cryptographic verifier injection for non-demo proofs, and block demo mode when running in production.

demo proofs ≠ production verification

Official wallet path

The EUDI-compatible wallet path is being researched, not enabled. GoAnon Verify will only enable official wallet support after the privacy behavior, trust model, and verifier implementation are clear.

EUDI-first

Disabled wallet scaffold

The codebase contains a disabled EUDI wallet scaffold that models the future request shape. It cannot be used as a live connector in the current alpha.

OpenEUDI evaluation

Verifier candidate research

OpenEUDI is being evaluated as a possible future verifier-side candidate for OpenID4VP-style EUDI Wallet presentations. No OpenEUDI dependency or live adapter is enabled yet.

Privacy gate

Digital Dignity checks

Official wallet support must avoid exact birthdate disclosure, stable wallet identifiers, raw ID sharing, biometric sharing, and per-use tracking by issuers, government endpoints, GoAnon Verify, or the broader GoAnon ecosystem.

For websites

GoAnon Verify is designed for cooperating websites that explicitly request a privacy-preserving age proof. It is not a bypass tool and does not manipulate third-party platforms.

Integration model

Ask only for age eligibility, not full identity.
Generate a high-entropy single-use server challenge.
Bind the proof to the expected challenge and audience.
Consume challenges only after successful verification.
Reject reused challenges to prevent replay.

Production requirements

Reject demo/local-test proofs by default.
Use a real wallet, EUDI, selective-disclosure, or ZK verifier before production use.
Validate issuer or trust-anchor policy.
Avoid storing raw challenges or full proof envelopes in logs.
Do not claim legal age verification until reviewed.

Private alpha: GoAnon Verify is currently an experimental tool inside the GoAnon ecosystem. Public installation links will be added when the Chromium and Firefox extension releases are ready. GoAnon Verify proves eligibility, not identity.
