Who is this?
I'm a software developer. I was previously a senior software engineer and tech lead at Google, where I worked for around eight years on Maps/Earth, Gmail anti spam, signup abuse and login security. In 2014 I left Google to focus on Bitcoin development full time. After two years of doing that, I joined R3 as the lead platform engineer, where I led development of the Corda project. I am currently working on a new developer platform, to launch some time in 2021.
I write a blog at blog.plan99.net, which covers a mix of programming, politics and economics.
I was a Bitcoin developer for about five years, and one of the earliest Bitcoin users. I had a variety of conversations over email with Satoshi Nakamoto before he departed the project, which I have since published as documents of historical interest. Many of the discussions cover topics that were long since documented or resolved, but back in these early years very little about Bitcoin was documented or understood, so asking Satoshi directly was the only way to get clear answers. None of these email discussions contain any clue as to his identity.
I have given a variety of talks on Gmail, Bitcoin, Corda and the future in general.
