On July 24, OpenAI founder Sam Altman and CEO Alex Blania jointly launched the encryption project Worldcoin and its token WLD. The two founders stated in the open letter that Worldcoin consists of a privacy-protecting digital identity and digital currency WLD, aiming to create a new identity and financial network owned by everyone. They emphasized that Worldcoin is an attempt to coordinate on a global scale, and the process will be full of challenges and the results are uncertain. Yet finding new ways to broadly share the coming technological boom is one of the serious challenges of our time. Let us wait and see whether Worldcoin can realize the vision of UBI economics in the AI ​​era and bring disruptive changes to the world.
