Great thread idea! I have been thinking a bit about this lately too. It seems important to disambiguate between apps that would work on POI map, vs tools that would require dPOL. (Full disclosure, I work at Enigma so I’m particularly curious about applications at the intersection of data privacy & location services.)
(poi map only)
secret scavenger factory
Similar to blockcities game, but the treasure is placed initially and the reward process is automated. This could be interesting especially if one clue leads to another, and you want everyone who places a POI in the zone to receive the next clue immediately. It could also make it easier to create a game with many winners without publicly publishing the answer…
Other thoughts on POI map
Right now, it seems like placing and curating points of interest is the main functionality. That’s cool, but I think Foam can also be used to make general location-specific claims about things on-chain. For example, I wonder how etherisc’s hurricane insurance app records your home’s location. (https://hurricaneguard.io/).
"Find my friends" w/ private defaults:
get a notification when you and anyone on your list are within x meters of one another. Have the option to push your info to them, but not shared automatically
Airdrop to addresses within a specific zip code only (location-specific advertising? scary but cool!?). Could be integrated someday with a messaging tool as well. If users kept their location a secret, the zip code query could be done in such a way that the sender doesn’t know your zip by default, only if it matches their query parameters.
Decentralized captive portal for dapps?
A captive portal is what you see when you’re in an airport and while unpaid can only look at southwest dot com sites and so forth. when you pay you are then connected to another network (with real internet). This is all handled with special captive portal routers (afaik!), but possibly something interesting could be done to enable location-specific site access.
Love to hear what others are thinking, too!
