(Bloomberg) -- Kenya’s interior ministry has suspended the activities of Worldcoin in the East African nation, as local authorities probe the possible security and data protection risks associated with the eyeball-scanning cryptocurrency project.

“The government has suspended forthwith activities of Worldcoin and any other entity that may be similarly engaging the people of Kenya until relevant public agencies certify the absence of any risks to the general public,” Interior Secretary Kithure Kindiki said in a statement on Wednesday.

Worldcoin — which launched last week — is an effort to create a global network of digital identities by using a small device called an “orb” to scan people’s eyeballs. That identity, or World ID, grants its holder “proof of personhood” in the Worldcoin parlance. Users are rewarded for participating with Worldcoin tokens. 

More than 2 million people have signed up for a World ID so far, reflecting the novel compensation model and the reputation of one of its founders, Sam Altman, the chief executive officer of OpenAI, which created the popular ChatGPT chatbot service.

In addition to the digital ID, some Kenyans received 7,000 shillings ($49) in cash incentives and crypto tokens, which drew thousands more to recruitment centers, local outlet Citizen Media reported on its website.

Kenya’s Capital Markets Authority said that Worldcoin products are not regulated in the country and advised people to be “wary of potential fraudulent schemes that may emerge in the over-the-counter market of crypto tokens,” according to an emailed statement on Wednesday. 

Demand in Kenya has been “overwhelming” with tens of thousands of individuals waiting in line over a three-day period, a spokesperson for the Worldcoin Foundation said in an emailed statement. Verification services have been temporarily paused “out of an abundance of caution and in an effort to mitigate crowd volume,” the statement said.

“During the pause, the team will develop an onboarding program that encompasses more robust crowd control measures and work with local officials to increase understanding of the privacy measures and commitments Worldcoin implements, not only in Kenya, but everywhere,” the statement said.
