So you may be heard this couple of weeks ago. Still it's so hype in the twitter. So wordcoin is offering 70-80$ airdrop for those who own s wordcoin id. To get Id you need to verify you via iris scanner. So right now there are long queue to get a id. Most of people doing this because of that free airdrop. But no one is thinking about the consequences of this. I mean we don't know what will they do the data that they collect from us. They never mention why they implemented iris scanner, what will they do with those data collect from scanning peoples eyes.
So why people don't afraid for this situation. For 70$ they sold their data. What happens if worldcoin use this iris data for illegal activity?
Human Identification is important (not necessary though) in cryptocurrency space but shouldn't be done in this manner.
A Crypto compatible human identification scheme should be decentralized p2p identification and verification. It's either done online(virtual world) or offline (physical world) or both.
We have written extensively on both... but I want to dwell abit on the offline/physical part today. It could simply be done by randomly selecting reputable verifiers or people on a decentralized ID system and assigning them to people who wish to ID themselves physically. Locations where the identification and verification can be safely done by the peers is randomly selected for them. They meet at the locations and the verifiers compare the peers IDs with their physical appearances, then use the peers phones or specialized cameras that cannot save copies of the owners IDs, to take photos of the peers and their IDs (probably via the decentralized ID application/system) and immediately have them saved on the ID system. Once saved it's thoroughly encrypted and the private keys given to the owners.
The owners can always use the private keys or corresponding public keys/addresses for certain transactions, websites/dapps authentications etc. And blue "verified" checkmarks shown on their profiles on the Decentralized ID system... including the public keys of their verifiers and their reputation scores. Verifiers reputation could be scored by other verifiers(who should aswell be randomly selected) during second verification of owners IDs by 1 or 2 of the verifiers, and the date of the verification could be random.
This method is Bitcoin-friendly and way safer
