Troy Cross is a Professor of Philosophy and Humanities at Reed College in Portland, Oregon, USA. He has formerly taught philosophy at Yale University and Oxford University, specializing in metaphysics and epistemology.

Troy has long been interested in bitcoin, and began mining himself in 2011. He is now a Fellow at the Bitcoin Policy Institute, a non-profit educational organization advising media, policymakers, and the public. 

Along with fellow philosopher Andrew Bailey (Yale-NUS) Troy has devised a new and simple method of holding bitcoin that is carbon-neutral. This led to relations with companies and groups across the bitcoin industry that align with the vision of bitcoin serving as a tool to accelerate the energy transition.
