I also talked to them about a possible WoT nostr integration. Great to hear that it is on their minds. 

I was a bit worried about the phone number kyc - they told me that only a hash of the phone number is stored on their side.  

 i asked the exact same question and was told the exact same thing too. great seeing you again for a few minutes, Florian. sorry we didn't get to talk more. the booth was crazy busy.
