Worldcoin recently underwent a major upgrade, announced by its founders Sam Altman (also the founder of OpenAI) and Alex Blania. The upgrade includes four main aspects:

1. **Iris authentication threshold is lowered**: Previously, users needed to go to countries and sites that support offline iris authentication for authentication. But by 2025, users will be able to buy an Ord device online, just like buying a camera to take home, so that family and friends can authenticate.

2. **App comprehensive upgrade**: Worldcoin's App will be fully upgraded to support access to various global applications, and plans to connect to some commonly used social platform apps, so that with a Worldcoin in hand, AI can be used to achieve various scenarios and services.

3. **Join hands with NVIDIA to launch a new generation of Orb and its own chain**: Worldcoin will be renamed World Network, support open source, and users can customize and create their own AI tools.

4. **Reward mechanism**: As long as the authentication is passed, everyone can receive a reward of no less than 3 WLD per month, which can be used to directly experience the use of Worldcoin applications or directly converted into US dollars.

These upgrades show that Sam Altman's ambition is not just as simple as OpenAI's GPT. He emphasized that AI is developing rapidly and will change our economic and social structures. Through these upgrades, Worldcoin aims to build a public facility for the world's largest identity and financial network, enabling ownership for all and creating universal access to the global economy regardless of country or background, accelerating the transition to an economic future that benefits everyone on the planet.
