v0.1.0-alpha — Proving Reality (Early Build)

This is the first working prototype of the hash-chaining-camera project — a proof of concept showing how sensor data provenance can be achieved using cryptographic chaining at the edge.

Overview

This early release demonstrates how sensor data (images, timestamps, and metadata) can be hashed, chained, and verified to ensure integrity from the moment of capture.
The goal is to build tamper-evident sensor systems for AI, robotics, and autonomous platforms.

Features

  • Real-time sensor capture and hash chaining
  • Cryptographic verification of data sequence (SHA-256)
  • Persistent log of chained sensor events
  • Lightweight Python-based implementation
  • Tested on Jetson Orin Nano and Raspberry Pi 4

Current Status

  • Working edge prototype
  • Early visualization of hash links and timestamps
  • Basic data integrity verification pipeline
  • Limited error handling and logging

Coming Next

  • Secure signing with hardware crypto module (ATECC608)
  • Web dashboard for provenance visualization
  • Multi-sensor data support (camera, IMU, GPS)
  • Integration with cloud verifier and blockchain anchor
