, I made a series of live streams in 2024 explaining how BOLT 11 is implemented in Core Lightning.  I'm no longer working on LN, but I guess the implementation has not changed much, and neither has the protocol, at least for BOLT 11.

Today we are going to look at the transformation of the information of an invoice from its representation with bytes of 8 bits to bytes of 5 bits.  Specifically, we'll try to understand why the description 

 of an invoice is represented in a BOLT #11 string by 

lightning

Excuse me, but wtf is `0b25fe64500d04` in this bolt11 test vector??

Hey @ek, I made a series of live streams in 2024 explaining how BOLT 11 is implemented in Core Lightning.  I'm no longer working on LN, but I guess the implementation has not changed much, and neither has the protocol, at least for BOLT 11.

I think you may find part 4 interesting.

I hope this helps.
