I'm assuming they don't store the images in the same way we don't store plain text passwords.
Earlier quoted context omitted.
Well, they claim not to save the images, just a hash.
As-if you can ever actually hash a biometric and expect it to match in the future. The whole idea of a hash is that a tiny perturbation makes the output completely different. It almost by definition cannot work for biometrics.

The "Become an Orb Operator" link has got to be satire.

In these field tests, people are waiting hours to receive their free share of Worldcoin [...]. Using dark patterns like artificially limiting supply before the product is even released to create an illusion of demand pretty much says everything you need to know about this.

That would be a cryptographic hash you are describing. Not all hash functions share that property. As long as arbitrary input is mapped to a fixed size output it is a hash function. For example see NeuralHash [1] which is a hash function designed to be "insensitive to small changes in the input image."

So, my understanding of the current play in this space is as follows: - Create a large number of worthless cryptographic tokens. - Distribute around half of them as "freebies". - Keep the other half to yourself / distribute them among your investors. - Start a hype by injecting your investors money into your currency. - Hope that people will start to trade/speculate with your currency, buying it for real monies. - As…
