Edward Snowden Slams Sam Altman's Worldcoin: 'Don't Catalogue Eyeballs'
Worldcoin issues tokens to people for scanning their retinas. Their magical orb device sends a biometric hash to their network.<p>Here's my take on it: You can possibly replace their biometric device with a random hash generator.<p>* If it works, it means the currency is not fairly distributed, but anyone sending valid hashes to their network is issued tokens, irrespective of whether the eyeballs described by those hashes exist. This is called a Sybil attack.<p>* If it doesn't work, it means there is some secret or centralized check that the network performs, which means the currency is not open.<p>This is why we still use proof-of-work in spite of its energy expense: it is simple to understand, it can not be faked, and it can be openly verified.<p>So, do not support this biometric-gathering enterprise.
