Worldcoin says 2.2 million have signed up, mostly during a trial period over the last two years.
Worldcoin raised $115 million from venture capital investors including Blockchain Capital, a16z crypto, Bain Capital Crypto and Distributed Global in a funding round in May.
Macieira said Worldcoin would continue rolling out operations in Europe, Latin America, Africa and "all the parts of the world that will accept us."
"The idea is that as we build this infrastructure and that we allow other third parties to use the technology."
Michael Will, president of the Bavarian regulator, said it would look into whether Worldcoin's system is "safe and stable".
