"When I started working for money I became interested in the 2008 crash & thought there needed to be something better. This is where bitcoin grabbed my attention."


Rootzoll is a prolific Berlin based Bitcoin Developer, who puts superhuman amounts of energy & talent into – a hugely respected Lightning & Full Node open source project. He’s involved with Fulmo, an open source company dedicated to research, development and consultancy for the Bitcoin Lightning Network. He also runs Lightning Hackday events in Berlin & beyond.


After his studies, when needing to go out and earn a crust, he became more and more interested in the concept of money. Witnessing the 2008 crash fuelled this interest further and sparked ideas of money without banks.

"Bitcoin is Prototyping a Better World.


All of that formed the perfect, fertile ground for when he first encountered Bitcoin a little later. Here was a manifestation of these ideas of a sovereign money. For the first time, there was a chance of something killing the monopoly on the production of money. Separating Money & State. For someone who had long been harbouring these thoughts, the wait was over. Bitcoin had appeared & with it hope for a better world.

"On a social level bitcoin has been a very interesting journey. I’m normally more of a nerdy person who likes to be by myself a lot but meeting Bitcoiners has changed me.


Bitcoin changes and challenges a lot of previously held ideas, habits, behaviour etc. Most of us feel it. Most of us have seen changes in our personal lives because of Bitcoin. From spending habits to diet. From changing to a delayed gratification lifestyle to political views and fitness. For Rootzoll one of these behavioural changes was born out of going to Bitcoin Meetups and Conferences. Selfbankt has had the pleasure of meeting Rootzol both at 2019’s first Lightning Conference in Berlin and at a Cardiff Meetup.

The projects he worked on also gained momentum after engaging with the community at events like this and resulted in more robust code too.
