Become a sponsor to Sjors Provoost

Sjors Provoost

Utrecht, The Netherlands

I've been contributing to Bitcoin Core on a part-time basis since mid 2017. Most of my time is spent on reviewing and testing work by others, but I also created my own pull requests. Bitcoin ACKs provides a nice overview of my activity on the repo. For a deep dive into the process, listen to my interview with Stephan Livera.

My focus recently, when not distracted by shiny object syndrome, has been on helping out with adding hardware wallet support. I gave a presentation about the state of the art at Advancing Bitcoin. Any on-chain funds received on this site go through my own experimental pull request(s).

If you prefer to sponsor me using Bitcoin, please see email me.

For questions, feel free to reach out to me at, Twitter @provoost or Mastodon.
