Ask. Search. Learn. Repeat.

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.

I’m a PhD candidate at UAB with a predoctoral fellowship, continuing a research path that I’ve been shaping over the past years there. Until August 2026 I was also a substitute professor, teaching the lab sessions of the Computer Networks course in the Computer Science degree and 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. This summer I’ve been contributing to BDK through Summer of Bitcoin.

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!.
