Sup 
I like to introduce Show Up Protocol here. A project I’ve been working on the past couple of weeks.
Onchain RSVP and Event management.
Show Up reduces no shows by aligning the incentives between event organizers and attendees.
- Organizers request a deposit fee on registration which is returned when showing up
- Active attendees get rewarded and earn $$ by showing up at events!
win/win for everyone
