Worldcoin, the cryptocurrency company founded by OpenAI CEO Sam Altman, is partnering with German manufacturing giant Jabil to ramp up production of its iris-scanning orbs. Worldcoin plans to launch its mainnet in the first half of this year, at which point it will be able to produce 400 orbs per month. This week Worldcoin launched the World ID protocol and software development kit. World ID is described as Worldcoin's "underlying identity protocol," powered by zero-knowledge cryptography that people can use to prove they're authentic without sacrificing anonymity. Regarding the SDK, Worldcoin has invited developers to sign up for a waiting list, and the product will be open to all users, including web widgets, a developer portal, a development simulator, samples and guides.
