Become a sponsor to Fabian Jahr
Hi! I am Fabian and I am an independent contributor to Bitcoin Core.
I spend most of my time reviewing and testing pull requests and digging into any parts where I find potential bugs to be fixed or improvements to be made. My biggest contribution that is currently in progress, is the coinstatsindex
. It makes auditing the coin supply for potential unwanted inflation much easier and efficient.
Aside from contributing to Bitcoin Core, I hack on smaller projects (example Lightning Vending Machine) and I spread technical knowledge of bitcoin through Bitcoin Socratic Seminars. I organize and co-host the Berlin Socratic Seminar on a monthly basis and I have hosted seminars in Ho Chi Minh City and Frankfurt (Main) as well.
If you would prefer to send me sound money instead you can find a BTCPayServer donation button on my website by clicking on the menu button: https://fjahr.com/ (JS needs to be enabled).
Thanks for checking out my profile!
