NFC Worldcoin Vote
Vote with a NFC wristband from ETH Brussels, with sybil verification from Worldcoin
About
User can vote IRL for DAO proposals with a wristband. Worldcoin verifies that it's a real human. Unfortunately I couldn't finish the whole app on time, because my first idea was related to rewriting the NFC chip itself to lead to a different URL, and then I realised the NFC wristband is protected for writing, so I pivoted to more simple idea .
How it's made
I extract ethereum signature from ETHBrussels wristband through using the library Libhalo called from mobile React Website through touching the wristband . Then user Sign In with Worldcoin to authenticate it's not a sybil . Then user can vote for DAO proposals IRL with a wristband by using the earlier extracted signature
