About

What you need to know about me:

  • CTO Emeritus at Ripple, the company behind the Ripple settlement network.

  • One of the original architects of the XRP Ledger system, the first to solve the crypto-currency double spend problem without requiring either a central authority or proof of work.

  • My alter ego is "JoelKatz" on the Bitcoin forums and other places.

  • Follow me on Twitter -- @JoelKatz.

  • Areas of expertise include cryptography, payment and settlement networks, advising fintech and emerging technology startups, and C++ programming.

  • Areas of interest include computers, aviation (both full scale and model/drone), basketball and football.

  • My wife and I have a blog, but it's only rarely updated.
