Hey Kakmakr!

That's correct.  Non-coders do not have to pay the 100 satoshi "proof of node" payment to register.  But conference tickets are 250,000 (~$10) satoshis per session.  If you don't have a lightning node, you can always pay on-chain via submarine swaps.

After the event, we will probably host the videos somewhere.  Just got to figure out which platform and how.  Hope to see you there!
