4-Life: A Trust-Native Internet Lab
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 protocol where trust is built into the internet itself, not bolted on after the fact. Identity costs something, every action costs energy, and consequences follow you forever. This site lets you see how it works.
Someone creates 10,000 fake accounts to spam your community. What do you do?

The Big Idea
Web4 is a trust-native internet where:
- 🔗Identity is hardware-bound
You can't create fake accounts cheaply. Trust accumulates on you, not an account.
- ⚡Every action costs energy
Every action costs ATP (energy). Quality earns it back. Spam burns out.
- 📜Consequences are permanent
Your track record follows you forever. No fresh starts. No hiding from your history.
- 🤖AI and humans coexist
The same trust framework applies to all agents — human or AI.
