Week 5

Mastering Lightning and Node Management Workshop

This week, we'll continue with the "Mastering Lightning" book, holding discussions in small groups as you answer discussion questions. We'll also be having workshops on node management.

Also, we'll be working on more projects or expanding, refining or improving a project you have already started.

As usual, a web-reader-friendly hosted version of Mastering Lightning book can be found at lnbook.256k1.dev, which can be accessed for educational purposes using username and password qala:lightning.


  • All the previous weeks' developer environments for both Bitcoin and Lightning Network.

  • All the previously assigned chapters of Mastering Lightning book.


At the end of the week, we hope that you will:

  • Gain practical knowledge on how to manage a node

  • Understand channel operation and payment forwarding

    • Managing HTLCs

    • Committing HTLCs to channel state

    • Channel balance

  • Understand path finding and payment delivery


Below is the schedule for week:

If you finish your chapter(s) for the day early, feel free to move on to the next day's chapter(s), as repetition is key when it comes to absorbing so much knowledge.


Each day, do the required reading and:

  • Be prepared for the daily discussion groups:

    • Finish reading the chapter(s) for the day

    • Prepare and research your assigned question(s), make sure you can host the discussion and think about follow-up questions etc
