Sergey Potekhin, Senior Blockchain Engineer

I'm a blockchain engineer based in Abu Dhabi with 8 years of experience. Vast, unexplored potential of blockchain technology is my passion. I find zero-knowledge technology fascinating and have been actively engaging with it since the beginning of 2023. As a true geek, I spend a lot of time at tech meetups and on open-source projects.
