for strictly web2 ppl, maybe lean on the dynamic qr code to funnel them into a patch wallet (@corbpage ). this is just my rough idea, but yeah, as a repeat organizer of POAP events and IRL attendee, there's room for improvement.
and re: sybil resistance, if dynamic url QRs are deliberately apart at a distance as stickers, then maybe a nonsybil will go to the trouble of walking from kiosk to kiosk in a reasonable window to mint, otherwise index++ for tardiness. again, just riffing.
as the owner tho wouldn’t you want some top-down control? in the case of a protest or strike i get it, but how common is the need for a POAP there relative to a branded event? i like the point of dynamic qr codes tho… also wonder if mentaport.com could help here cc @cynthai
