Imagine a world where you can prove you are financially stable to rent a new property without having to hand over a bank statement or a job offer letter. Or a world where you can apply for a job based solely on your credentials, without revealing any information about yourself (including race, gender, or even name), while still providing a guarantee to the company that the information on your resume is 100% true.
Or even a world in which prove to the government that I paid my taxes correctly without even telling them who I am or how much I make or how much money I paid. These are all impossible today, but zk-SNArKs are a new cryptographic primitive which will make these things a reality in (I believe) the rather near future (despite the fact that most people don’t even know about them).
