# Web4 at AI Demo Day 4 (April 26, 2026)

This document records the public framing of Web4 delivered at AI Demo Day 4 — the audience-tested narrative for short-form, mixed-audience contexts (builders + investors + technologists).

The full delivered deck and speaker notes are archived at https://4-gov.org/demo.

## The opening (the headline that opened the door)

> **AI is already taking actions in the world. We can't prove what it did.**

That's the gap. Web4 closes it.

## What Web4 is — in plain language

Web1 was access. Web2 was participation. Web3 was ownership.
**Web4 is verifiable presence.**

Or, fractally:

> **Web4 is presence.**
>
> **Presence = identity + trust + context + accountability.**

It's an open standard, proposed by Metalinxx Inc., owned by no one. Anyone can build on it.

## The proof point

Same Claude Opus 4.6 that you can sign up for today.

- Default setup on ARC-AGI-3 (the hardest public reasoning benchmark): **0%**.
- Same model, structured around Web4 patterns via the SAGE cognition harness: **94.85%**.

No fine-tuning. No additional training. The model didn't change. The structure around it did.

The takeaway: the leverage isn't in the model. It's in the structure around the model. Web4 is that structure.

## What it enables — the four pillars made concrete

- **Identity** — Agents can prove who they are. Checkable, not asserted.
- **Trust** — Earned from observed behavior. Witnessed. Auditable.
- **Context** — Trust scoped to where it's earned, not assumed globally.
- **Accountability** — Every action traceable to its authority and consequence. Not log files. Verifiable records.

## Hardbound — Web4 in production

The open standard is free. **Hardbound** is Metalinxx's enterprise deployment for environments where "trust the model" is not an acceptable answer — regulated industries, high-stakes operations, anywhere an agent's actions need to stand up to audit.

Use cases: finance, defense, healthcare, infrastructure.

> If an AI approves a transaction, you can prove why — on whose authority, under what rules, in what context. Verifiable by a regulator or counterparty.

Hardware-bound identity. Verifiable audit chains. Contextual, computable trust. Contact Metalinxx Inc. via the [project repository](https://github.com/dp-web4/web4) for evaluation and deployment.

## Why this matters now

Standards become real when people build on them early. TCP/IP. HTML. Same shape: a few people defined them, then everyone else built on top — and that's when the standards became real.

Web4 is at that early moment. The foundation works. It is evolving. The people who build on it now define what it becomes.

## How to engage

- **If you build with AI** — adopt the primitives. File issues. Push back where the spec is weak.
- **If you do AI research** — test the claims. Publish the failures. Propose extensions.
- **If you run an organization** — pilot a real workload. See where it bends.
- **If you write standards or policy** — review the ontology. Tell us what regulators will need.

Try it. Break it. Tell us where it fails. **Help us make it work for everyone.**

*This is the audience-tested public framing. It does not replace the technical specifications — those live in `web4-standard/core-spec/`. It is the entry point for people who haven't yet read the spec and need to know why they should care.*
