Hi, my name is Paweł Pokrywka and you are reading my blog.

My motivation

  • I believe we deserve better privacy, better security, better institutions, and we should fight for more freedom. There are some principles, ideas, and projects I want to promote.

  • On a few occasions, people wanted to know more about my research or the projects I'm working on. I want to share my research and contribute to the community.

  • We need each other. I want to connect with like-minded people to build great things together.

  • I also have some personal development goals, including improving my English and fighting my perfectionism. Expect errors in the text.

How & what?

Building on my over twenty years of experience in IT, my innate curiosity, creativity, and my desire for continuous growth, I decided to start a blog.

I write mainly on privacy, security, and blockchain-related topics.

Who am I?

I am:

  • Open Source enthusiast

  • in love with Unix

  • fascinated with computer networks and cybersecurity

  • a firm believer in the principles of the Cypherpunk philosophy


  • co-founder, co-owner, and CTO at one of the largest Polish wedding website

  • software developer and DevOps engineer


  • happy husband

  • keto follower

  • a vegetarian who encourages others to eat meat

  • Nonviolent communication practitioner
