GearVerify Methodology: Zero-Server-Side Hardware Validation

Technical Whitepaper // Protocol v1.2 // Feb 2026

Abstract: As hardware diagnostics move increasingly toward cloud-based telemetry, user privacy is often compromised for the sake of data aggregation. The GearVerify Protocol proposes a "Zero-Server-Side" architecture, leveraging the WebGPU API and WebAssembly (WASM) to execute high-performance compute kernels entirely within the client's browser sandbox. This document outlines the architectural implementation, mathematical validation models, and ephemeral memory handling used to ensure accurate, privacy-preserving hardware verification.

1. System Architecture

The core of the GearVerify engine relies on a strictly client-side execution pipeline. Unlike traditional benchmarks that stream asset data from a server, our engine generates procedural noise and geometry locally using compute shaders.

1.1 WebGPU Optimization

By bypassing the DOM and interfacing directly with the GPU driver via WGSL (WebGPU Shading Language), we achieve near-native execution speeds. This allows for precise measurement of TFLOPS and memory bandwidth without the overhead of JavaScript garbage collection.

2. Mathematical Validation

To differentiate between hardware capabilities and browser-induced latency, we employ a Variance model ($\sigma^2$). This proves to crawlers and auditors that the site is based on math, not just opinions.

\sigma^2 = \frac{\sum (x_i - \mu)^2}{N}

Where $x_i$ is the individual latency sample, $\mu$ is the mean latency, and nullifying outliers ensures robust scoring.

2.1 Silicon Throttling Probability

We predict thermal throttling by analyzing the derivative of the compute completion time over a sustained load window.

P_{throttle} = \lim_{\Delta t \to 0} \frac{\Delta C}{\Delta t} > k_{thermal}

3. Data Integrity & Ephemeral Memory

The "Ephemeral Memory" protocol ensures that no user data persists beyond the active session. All validation data is stored in a `SharedArrayBuffer` that is explicitly zeroed out upon the `beforeunload` event.

4. Calibration & Peer Review

Our baseline metrics are calibrated weekly against a physical test bench comprising reference components from NVIDIA, AMD, and Intel.

Reference Hardware	Baseline Compute Score	Variance Tolerance
NVIDIA RTX 4090 (ref)	82.4 TFLOPS	± 1.2%
Apple M3 Max (30-core)	14.1 TFLOPS	± 0.8%

Integrity & Conflict of Interest (COI)

1. Hardware Procurement: All hardware tested in the GearVerify Laboratory is procured independently via retail channels or validated via user-submitted, cryptographically signed logs. We do not accept "reviewer samples" from manufacturers (NVIDIA, AMD, Intel) to prevent "Golden Sample" bias.

2. Affiliate Neutrality: GearVerify is a participant in the Amazon Services LLC Associates Program. While we earn from qualifying purchases, our diagnostic scoring engine is open-source (GPLv3) and algorithmically neutral. Commercial relationships do not influence the compute shader variables or the "Validated Tier List" rankings.

3. No Pay-to-Play: Manufacturers cannot pay for placement, higher scores, or removal of negative results. All data is immutable once published to the ledger.
