Domènec Madrid
I’m Domènec, a Computer Science Engineer graduated from the Autonomous University of Barcelona. Later on, I completed a Master’s degree in Cybersecurity and Privacy at Universitat Oberta de Catalunya.
If everything goes as planned, I’ll be starting my PhD next September, continuing a research path that I’ve been shaping over the past years at UAB. In parallel, I teach lab sessions for the Computer Networks course in the Computer Science degree, and I’m currently supervising four Bachelor’s Thesis.
My deep interest in cryptography, privacy, and distributed systems naturally led me into the world of Bitcoin. I’ve worked on projects ranging from building a parallel Bitcoin mainnet environment in Docker for realistic testing, to hardware‑wallet fingerprinting, to analyzing anti‑exfiltration protocols and other privacy‑oriented mechanisms.
If you’re curious about any of this, you can explore some of my recent work in my blog :)
Outside the academic and technical bubble, I’m usually out hiking with my dog. I like staying in constant learning mode, so if you ever want to reach out or comment on something, don’t hesitate to contact me!.
