Sam Altman, the CEO of OpenAI, is leading the iris-scanning  cryptocurrency project known as Worldcoin, which is still in beta but  continues to draw investors.

Worldcoin is “in advanced talks” on a fresh round of funding for around  $100 million, according to the Financial Times, which cited three people with knowledge of the arrangement.

According to one of the people, the round has support from both current and new investors.

The last round of funding for Worldcoin includes contributions from the  venture capital companies Andreessen Horowitz (a16z) and Khosla  Ventures, raising the project’s estimated value to $3 billion.
