BitDevs Bitcoin Socratic Seminar Berlin

13. Mai 2026 19:00 CEST

c-base, Rungestraße 20, Berlin, BE, DE

BitDevs Bitcoin Socratic Seminar Berlin @ c-base Raumstation

Join us for our monthly interactive Bitcoin Socratic Seminar in Berlin! We’ll start with pizza and beer (sponsored by Ordimint.com), followed by deep-dive discussions on the most interesting technical developments in Bitcoin from the past month. Participation by everyone is highly encouraged!

Our goal is to foster lively discussion, knowledge sharing, and debate. In the weeks leading up to the event, participants gather topics such as:

• New research papers
• New BIPs and BOLTs
• Network statistics
• Technical blog posts
• Mailing list and Delving Bitcoin threads
• Pull requests and updates from key repos (Bitcoin Core, LND, Core Lightning, Eclair, BDK, rust-bitcoin, LDK, Electrum, …)

Each topic is briefly introduced by our moderators and then discussed before moving on. The full list of links will be published at bitdevs.berlin 1–2 days before the event — please review them in advance to get the most out of the discussion.

Important details:

• This event is highly technical — best suited for those with a solid grasp of Bitcoin internals. Curious newcomers are always very welcome, but expect in-depth conversations (see the former topics at bitdevs.berlin).
• Chatham House Rule applies: you may share what was discussed, but not who said it. No livestream, no photos, no recordings.
• The evening begins with food and networking; people often stay after the seminar to keep talking.

Co-hosted by:

• Felix
• Freerk
• Fabian
