Worldcoin has launched World ID 2.0, an upgraded version of its identity platform that introduces Apps, a new way to build and use integrations to verify online accounts using World ID. The platform has three "Levels" that provide access to a broader range of use cases, including face authentication. World ID Apps allow users to verify accounts and apply a verification status similar to the blue checkmark used on some social media platforms. The platform uses Zero-Knowledge Proof cryptography and has already seen almost 5 million individuals register for World IDs.
