Golden Finance reported that Worldcoin’s digital identification project on Ethereum may consume US$4.5 million in gas fees every year, thus driving corporate demand for Ethereum. The Worldcoin project spent $500,000 in gas fees on a zero-knowledge proof of retinal scanning in just 40 days. Worldcoin Orbs uses the cryptographic protocol zk-proofs to add the user’s World ID to a public list of verified people.
