Personal Statement

My Ice Breaker speach at Toastmasters. Or just me in seven minutes. In Polish.

I woke up after five hours of sleeping, had breakfast, and immediately jumped behind my computer, working late nights, completely immersed, forgetting all about eating and going to a toilet. Often the sunrise was my reminder about to go sleep. I had a clear goal, knew what I had to do, and the only thing separating me from reaching it was the work I had to do. I endeavored to create some app that would make me rich—a typical result of overdosing self-help books at a young age. I was obsessed; the priority was to learn, create and be useful. Programming gave me all of that. Everything else: undergrad, friends, and my girlfriend; had to be satisfied with the remnants of my attention.

What really mattered was the app. After two years of total devotion, I’ve created an app that reached over two million downloads and one hundred thousand active users  [1]. I was twenty-one years old, making deals with companies worldwide, paying more taxes than my peers were earning, selling a product—not time, everything alone, my self-esteem was peeking. I was making money out of math and programming, something I loved and was passionate about. The Holy Grail of making money from a hobby has been found. The trillema of doing (1) what makes you happy, (2) is good in the long-term, (3) and useful to others, has been solved.

I attempted to drop out of college many times—Steve Jobs and Bill Gates did the same, right? I wanted to be like them. Yet, at about that time, my little business started to face its first problems. Apple banned vape-related applications, cutting off half of my income. Facebook prohibited vape-related advertisements cutting off my ranges. Fortunately, by then, I’d had already fulfilled all my material desires and saved money so that I had time to reflect on what I truly want to do with my life. Clearly, it was not about earning money because I was spending only fraction of my income, living a minimalistic lifestyle; yet, still being very happy. Also, at the end of that period, I felt rather misunderstood, overwhelmed, and unmotivated.

I’ve finished the game. And what happens when we finish a game? We stop playing it. I’m ever grateful for the experiences that life has granted me so early in my life. It saved me a lot of time and helped me pivot my goals.

I decided to leverage my privileged situation and devote myself to my studies. Quickly, I found science to be as satisfying as creating apps. It has offered me an infinite source of hard challenges, equipped with formalisation techniques, and forced me to clearly and precisely communicate my ideas.

In 2017 I got interested in cryptocurrencies, initially because I wanted to invest money, then because of the technology. It intrigued me how Bitcoin transforms computing power into a currency, why it is unstoppable, how it prevents the Sybil attacks in an open network, and how the consensus works. The more I read, the more questions arose, so I kept reading even more. Every aspect of blockchain was highly appealing to me. Because my department specialized in computer networking and security, I started researching p2p networks, especially information-centric like IPFS, and game theory involved in open networks. For my Bachelor’s Project, I made a Bitcoin hardware wallet[2]. Then, on my Masters, I worked on the mitigation of content poisoning attacks in information-centric networking using blockchain [3], [4]. I researched the issue of internet voting and built a framework for i-votings using Stellar blockchain, a project for which I received the Stellar Community Fund [5], [6]. Recently, I dived into the world of cryptography and got interested in a relatively new field called zkSNARKs, which is—according to the co-founder of Ethereum, V. Buterin—considered the long-term solution to the issue of scalability and privacy of blockchains [7].

I think of the science behind blockchain technology as one of the most exciting fields in the current decade, hence my determination in contributing to it.
