Welcome to my (third) blog
Hello. I’m David Schwartz, better known as JoelKatz in many online communities. I’m the Chief Cryptographer at Ripple and one of the original architects of the Ripple global settlement network. In no way is anything said here official in any way or said in any capacity other than my capacity as a human being, so long as I continue to retain such a capacity.

My blog posts will be around my personal interests and experiences. You may see things about blockchain technologies, encryption, aviation, solar power, sports, and about anything else that I feel the world most know.
I picked the domain GigabitEther.net for my blog because it was a memorable domain that I’ve had for quite some time and never done anything with.
Maybe the third time will be the charm. Maybe not.
