Heritage
My four-times great-grandfather, Robert Dixon, was a Whitby Jet worker
on Henrietta Street during the Victorian era. I moved to Whitby in 2025.
The platform I'm building connects forty years of cryptographic expertise
with a direct family connection to the trade it protects.

What I Care About
Provenance
If you can't verify where something came from, trust is a guess.
Heritage
Whitby Jet has survived 180 million years. It deserves protection that lasts.
Honesty
Say what the system does. Say what it doesn't. Don't overclaim.
Craft
The maker's expertise identifies the material. The platform makes it unforgeable.
Accessibility
Built by a neurodivergent engineer. Designed to work for everyone.
Independence
No investors. No shareholders. No extraction. Community trust, not corporate greed.
The Platform
Authentic Whitby Jet
A provenance verification and supply chain integrity system for genuine
Whitby Jet jewellery. Every registered piece carries an NFC tag —
in the box, on a provenance card, or embedded in the piece itself —
that a customer can tap with any smartphone to see the full story: who
made it, where the jet was collected, and photographs of every stage
from beach to finished piece. No app. No account. Just tap and verify.
