Is Worldcoin real or fake?

I've been hearing a lot about Worldcoin lately, and I'm curious to know if it's a legitimate cryptocurrency or just a scam. Can you please explain what Worldcoin is and how it works? I've seen some claims that it's backed by a legitimate foundation and has the potential to revolutionize the financial industry, but I'm also aware that there are many fraudulent cryptocurrencies out there. So, I'd like to get your professional opinion on this matter. Thank you.
