One of our favorite ways to explain zero-knowledge proofs:
๐ชชShowing your ID at a bar proves the one thing the bouncer needs, that you're over 21. But it also reveals everything else: your full name, exact birthday, address, ID number.
A zero-knowledge proof is the version where you prove only the part that matters, "over 21," and nothing else.
That's one of the core ideas: prove something is true without exposing the data behind it.
And it goes way past age checks:
๐ prove you can afford a loan without revealing your balance
โ๏ธ prove a computation ran correctly without revealing its inputs
