Rex Kirshner
I travel. I take photos and videos. I run. I believe great stories happen to those who can tell them.
I'm a researcher, content creator, and consultant. Building off an education in computer science and a background in corporate finance, I provide strategic consulting to growing businesses while creating educational resources about Ethereum, hosting podcasts, and building communities around decentralized technology.
I also believe that Ethereum is the world computer—a globally shared piece of technology that will make the world more open, fair, and trustworthy.

Running Journey
In November 2016, as I was packing up to head home from work, I downloaded Couch to 5K and resolved to get started that night. Six months later I'd lost 100 pounds and finished a half marathon. Six months after that, I ran the New York Marathon in 3:35.
Since that first run in 2016, I've logged thousands of miles across 42+ countries. These days I make a point of running long distances wherever I am. I've experienced everywhere in a completely new way.
Each mile tells a story.
