On October 25th, Snowden criticized the Worldcoin project on Twitter, saying that it uses human bodies for encryption.
The project was founded by Y Combinator founder Sam Altman. It has received widespread media attention and has a valuation of $1 billion. It aims to reduce fraud and violations caused by robots and bad actors by scanning users’ eyeballs and rewarding cryptocurrencies. behavior. Snowden wrote: This seems to be the creation of a global (hash) database of human iris scans (namely for fairness), and then declared that the scans were deleted, as if it were all right.
But you save the hash generated by the scan and match it with future scans. Don’t catalog the eyeballs. We used the ZK certificate! Very good, very smart. But it’s still bad. The human body is not a ticket machine.
