"Imagine you're buying makeup, but you want to make sure that you're buying the good stuff without a bunch of toxic chemicals, reach out to 10 different testing companies and say 'here's $10k. first person to test this makeup and tell me if its good or not gets it. But you want to make sure the test was good so you you have the other companies double check the tests and make sure they're correct and conform to the right standards, so you pay the other companies $500 each.
not sure is this a good explanation, as I was thinking why can't you verify that yourself instead of relying on others 😂 but I'd happy to read your followup explanation too, because I don't understand that part yet...
