The Alaska is still in Prototype & Ideation stage, you will find missing documentation and many things will not work as expected.
I hope this documentation will help you to understand the architecture behind Alaska more clear

NOTE FOR ORGANISERS:

There are 5 Repositories containing the entire Project including Main Alaska Protocol, Alaska Indexer, Book Swap Vessel, Bike GPS Vessel & Alaska Docs. All 5 Repos are private except this docs. So, 4 repositories are Zipped in the submission :)
