What I've Learned (and Broken) Building Zero-Knowledge Applications | HackerNoon
Briefly

Zero-knowledge proofs allow you to prove you possess certain information, like sufficient funds or age, without disclosing the actual information, creating a layer of privacy.
I got into ZK stuff by accident while working on payment processing. Proving transactions without sharing customer data was a challenge until I discovered ZK proofs.
Some projects using ZK proofs were successful while others were disasters. A hilarious demo failure once showed a client how real-time debugging works.
The magic of ZK proofs lies in their ability to validate without revealing the underlying data. It's this blend of tech and mystery that keeps me fascinated.
