Nathan on Crypto

The only crypto writer my mom understands.

I write and podcast about blockchain - for everyone who's felt frustrated with their bank, wondered who checks their AI agent, or thought finance should be fairer.

Why this matters

I tell CEOs and CFOs the same thing I tell my mom.

AI-literacy alone won't prepare us for tomorrow. Crypto and blockchain are central to the story too.

They listen because I don't care whether or not they invest in crypto. I care that they understand the world being built around them - so they're not left behind.

Blockchain isn't a story for tech geeks or investors. It's a story for anyone who has felt frustrated with their bank, thought finance should be fairer, wondered who checks whether their AI agent is telling the truth, or felt that we don't have enough privacy online.

Inside an Oklahoma Bitcoin mine

I executive-produced a documentary that took us out to rural Oklahoma in search of a fascinating Bitcoin story. Published by Blockspace, a top Bitcoin media outlet. Have you seen a Bitcoin mine? I hadn't till I made this. It was fascinating.

About Nathan

Twenty years a journalist. Then I got obsessed with blockchain.

I'm a journalist, and I spent 20 years convinced that wars, elections and pandemics were the only things worth writing about.

Then I got obsessed with blockchain.

Today I write and podcast about it, while running the media desk at StarkWare - the blockchain infrastructure company - and serving as spokesman for CEO Eli Ben-Sasson.
