Welcome to the second Bitcoin Lightning Network Hackday! This will be the second of a series of Hackdays that we’ll host to explore and discover the Lightning Network! #lightninghackday

The Hackday is inspired by the idea of Barcamps and Unconferences. This means: The more you put in, the more you get out! Explore, learn, share, build!

This will be a technical event, so be ready to nerd away! We also expect this event to be overbooked, so please make sure to fill out the RSVP properly and ONLY respond if you actually plan to participate.

We will have a bigger focus on building LApps (Lightning Apps) this time, so people who RSVP with their idea for a LApp have a higher chance to attend.

Here’s the schedule for the event:

10.00: Doors open, registration, set-up.

10.30: Official welcome. Ideas for the barcamp tracks are pitched. This can be anything: Presentation of an excisting project, a workshop, a discussion. You can prepare something in advance or make something up on the spot. Bring your own topics, problems and questions.

11.00-11.30: Surprise speaker. It’ll be worth it, trust us.


Mainstage: Everything You Always Wanted to Know About Lightning* (*But Were Afraid to Ask) – an interactive deep dive into the Lightning Network. This three-hour track will cover the basic of the Lightning Network, e.g. Payment Channels, HTLCs and Onion Routing on LN. You need to have a good understanding about how the Bitcoin Blockchain works in order to attend this workshop and get the most out of it. And you’ll also play a part in it – literally. Stefan (, co-founder of and co-host of the Honigdachs podcast ( will lead this session.


Barcamp tracks.

Setting up a Lightning Node on a Raspberry Pi. We’ll provide some fresh Pis, but you may also bring your own device. (And it doesn’t necessarily have to be a Pi.) Christian ( will be there to help you through the process.

Hacktrack. Build your own LApp (Lightning App) or anything related to the Lightning Network you’d like to work on and demo later. We’ll have some prices and also the chance to demo at a different event in front of Lightning Network and Layer 2 developers. Details tba.


Demos of the LApps.

After that, we’ll head out to room77 to have some Beers and Burgers and hopefully pay via Lightning. Or help room77 set up Lightning payments. There are some specials waiting for us at room77.

Please note that this schedule is subject to change. If you have any suggestions or projects, please don’t hesitate to contact us.
