What is worldcoin & how does it work?

Worldcoin officially launched in July, with the project embarking on a multi-city sign-up tour. Altman posted a video of long lines outside Orb centers, and said that the project was scanning in a new user every eight seconds. Worldcoin claims that more than two million people have registered for World IDs.

What is the difference between a worldcoin login and a zero-knowledge proof login?

The difference, Altman argues, is that a Worldcoin login will be more secure and unlinked to other information, including a user’s email, name or photograph. If the zero-knowledge proof aspect of the tech works properly, Worldcoin would allow ID holders to log into a website without that action being traceable by other people or any government.

Why did people sign up for worldcoin?

But many more, it seems, signed up for a simpler reason: money. In order to galvanize interest in the project, Worldcoin created its own crypto token, called WLD, and has offered 25 units (currently worth about $60) to anyone who scanned their eyes into an orb.
