The Internet Lost the Human Signal
When bots can replicate everything humans do online, the only unforgeable proof left is physical presence.
Presence Infrastructure
At the heart of 7aychain is a simple idea: your internet connection can prove where you are. Validators across the network measure connection timing from multiple points, confirming physical location without GPS, cameras, or special hardware.
Most identity systems rely on behavior, accounts, or credentials. At scale, all can be faked. 7aychain takes a fundamentally different approach: it uses the laws of physics.
Bot resistance through physical reality
Instead of trusting profiles, credentials, or biometrics, 7aychain exploits a fundamental constraint: you can only be in one place at a time.
Physics, Not Scans
Internet signals obey the speed of light. 7aychain uses this to confirm where you are. No iris scans. No selfies. No fingerprints.
One Place at a Time
Create a million wallets — you can still only be in one physical location. That constraint makes bot attacks nearly impossible.
No Lasting Footprint
Each verification is ephemeral. No persistent profile, no behavioral tracking, no stored data. Prove you were here, then it's done.
In a world of perfect simulation, physical reality is the scarce resource
AI generates convincing text, behavior, and interaction at scale. But physical presence — being at a specific place at a specific time, measurable through network physics — remains constrained by natural law.
Bots fake behavior at scale
AI fakes text, transactions, and social activity. It can't fake being somewhere. Physical presence is bound by the laws of physics.
Anyone spins up unlimited wallets
New wallets cost nothing. Being in two places at once is impossible. 7aychain turns a digital problem into a physical constraint.
Biometric systems are surveillance
Iris scans and facial recognition create permanent databases of your body. 7aychain measures connection timing — it never sees your face or knows your name.
Social graphs can be manufactured
Coordinated groups fabricate social proof. Physical presence is independently verified by the network — no trust assumptions needed.
How 7aychain compares
Different approaches to bot-resistant identity. Each makes trade-offs on privacy, hardware, and what they actually prove.
| Dimension | 7aychain | Worldcoin | BrightID | Gitcoin Passport |
|---|---|---|---|---|
| Method | Network timing triangulation | Iris biometric scan via Orb | Social graph via video calls | Aggregated account scoring |
| Hardware Required | None — any internet connection | Custom Orb device | None | None |
| Collects Body Data? | No — zero biometric data | Yes (iris scan) | No (face visible on video) | No |
| Privacy | High — location verified, identity never revealed | Low — stores iris biometric data | Medium — face exposed during verification | Medium — links existing accounts |
| What It Proves | You're physically at a real location | You're a unique human (biometric) | People vouch that you're real | You have active online accounts |
| Chain | 7aychain (Substrate L1) | Optimism (L2) | IDChain / multi-chain | Multi-chain (off-chain scoring) |
| Stage | Devnet (v0.8.26) | Mainnet | Mainnet | Mainnet |
