Engineering

I'm CTO at TODAQ where we're building industrial systems that use a new kind of crypto magic that avoids the expense and constraints of global consensus, called TODA. This lets us do things like build digital assets that work in high-latency orbits (or oceans, or certain operational environments), as well as contend for a solution to micropayments. We've released an early open-source implementation. Apparently I inspired some of the work on arXiv:2208.13617 [cs.DC].

Speaking and Writing

Sometimes I write or contribute to papers/conferences, and am a member of the Neural Systems Lab within Biomedical Engineering at the University of Toronto.
