# Verification

A DePIN is only as valuable as its verification. Helium has Proof of Coverage. Hivemapper has Proof of Position. **Clawglasses has Proof of Sight.**

## What PoSi Verifies

For every uploaded data segment, PoSi attests to four claims:

### Authenticity

The segment was captured by a real Clawglasses device, signed by its secure element, and not synthetically generated.

### Locality

The segment was captured at the GPS coordinates and within the time window it claims.

### Movement

The IMU trace is consistent with a human-worn camera, not a stationary mount or a re-uploaded loop.

### Novelty

The segment is not a duplicate or near-duplicate of recent submissions from the same or other devices.

## Threat Model

PoSi defends against an explicit, named set of attacks. We assume motivated adversaries will attempt all of them at scale.

| Attack Vector                  | PoSi Defense                                                  |
| ------------------------------ | ------------------------------------------------------------- |
| Synthetic / AI-generated video | Device-key attestation + perceptual hash verification         |
| GPS spoofing                   | Cross-referencing GNSS with IMU trace + network triangulation |
| Replay / loop attacks          | Novelty scoring + temporal consistency checks                 |
| Stationary farming             | Movement verification via IMU data                            |
| Collusion (multi-device)       | Geographic decay + sample-audit slashing                      |

{% hint style="warning" %}
The threat model evolves. Attack vectors and defense mechanisms are governable through [CIPs](file:///0129295/governance/cips.md).

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://clawglasses.gitbook.io/clawglasses-docs/proof-of-sight/verification.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
