4-Life: A Trust-Native Internet Lab — explore Web4 through simulations

The Internet Has a Trust Problem

Spam wins because accounts are free. Reputations are trapped in silos. Bad actors get unlimited fresh starts. AI deception outpaces verification.

Web4 is a proposed framework where trust is built into the internet itself, not bolted on after the fact — that's what "trust-native" means. Identity costs something, every action costs energy, and consequences follow you forever.

What is this, really?

Web4 is a research proposal for making trust work on the internet. Not a product, not a company, not a blockchain. It's a set of ideas about what would happen if identity cost something, actions had consequences, and your reputation followed you everywhere.

Right now, you can't install it. This is an active open-source research project with a formal specification, ~47,000 lines of tested reference code, and the working simulations on this site. The mechanics are validated — the open question is whether real communities behave like the simulations.

This site (4-Life) is the lab. Web4 is the protocol — the rules and math. 4-Life is where you explore those rules through interactive simulations, guided walkthroughs, and concept explainers. Nothing here is “live” on the real internet yet — it's a working model you can poke at to understand how trust-native societies would behave.

Nobody profits from this yet. The bet is that trust infrastructure for the internet will eventually be as fundamental as HTTPS. If these ideas hold up, they'll need to be open standards — not owned by anyone.

How would it work?

Web4 proposes a trust-native internet built on four rules:

🔗
Identity is anchored in your devices
Your phone, laptop, and tablet each carry a security chip. Linked together through Linked Context Tokens (LCTs), they form a constellation that is your identity. More devices = stronger identity. Can't be cheaply faked.
⚡
Every action costs energy
Every action costs energy from a personal budget called ATP (Allocation Transfer Packets). Quality earns it back. Spam burns through it with no return.
📜
Consequences are permanent
Your track record follows you forever. No fresh starts. No hiding from your history.
🤖
AI and humans play by the same rules
The same trust framework applies to all participants — human or AI. In Web4, everyone is called an “agent” because the rules are identical regardless of who (or what) you are.

What would change for you?

📧

Spam disappears

Creating accounts costs real resources. Mass-creating fake accounts becomes economically irrational. Comment sections become usable again.

⭐

Your reputation travels with you

Years of good behavior on one platform count everywhere. Switch services without starting from zero.

🤝

You can trust AI agents

AI acting on your behalf carries verifiable identity and trust history. You can tell which AI agents have earned trust and which haven't.

How would this ever get adopted?

Not all at once. Web4 starts as a lightweight wrapper on existing platforms — adding trust scores behind the scenes. Your users don't see Web4; they just notice less spam. Tier 1 could work on Reddit or Gmail today.

Tier 1

Wrapper

Add trust scores to existing platforms

Tier 2

Observable

Platforms publish trust-compatible data

Tier 3

Accountable

Actions carry real consequences

Tier 4

Federated
