Previously, users were able to remain anonymous but transactions were verified by allowing everyone on the network to see them.

“Zero-knowledge proofs are one of the biggest inventions in the last two decades in cryptography,” said Emin Gun Sirer, an associate professor of computer science at Cornell University. It “will allow a slew of applications we can’t even imagine right now.”
