Work

Education built on expensive lessons.

Two ventures, one job: making sure people holding crypto actually get to keep it.

Blockchain Jon — Crypto Security Mastery

An 18-lesson security training taught in plain language, with no technical background needed. It covers the things that actually lose people money — wallets, recovery phrases, exchange risk, the daily habits and checks that separate people who keep their coins from people who tell loss stories.

Every lesson exists because of something Jon got wrong first, including the 9 BTC he lost learning security the hard way. That's the pitch: learn it from someone who paid full price, at a fraction of the cost.

Earlier: blockchain gaming & digital ownership

Before the security work, Jon spent years writing about digital ownership — most visibly around the Gala Games node ecosystem, where his explainers on decentralized gaming and player-owned assets reached a wide early audience. That thread — who really owns this thing? — runs through everything he's done since.
