What is this?

While planning the Chaincode Residency, we put considerable effort into finding the best resources and creating a curriculum around Lightning protocol development.

Lightning is still a nascent technology, and so we expect maintenance of this document to be an ongoing task. We could use your help. Please consider opening a pull-request to keep this document relevant.

There are three portions to this curriculum:

  1. Study Groups designed to provide bite-sized grouped subjects that you can either complete bookclub style or alone.
  2. Seminar Videos recorded during the Summer 2019 Chaincode Residency.
  3. Lightning Syllabus a collection of resources grouped by subjects.
