What is a zero-knowledge proof?
Zero-knowledge proofs are a cryptographic technique to prove something without revealing a secret. It's like a magic trick where someone shows they know a secret number without telling it.
For instance, in a locked box game, your friend claims to know the combination. Instead of telling, they make you pick a number, multiply by a secret, and give the result. They quickly divide it, showing the secret number. Repeating this, using different numbers, builds confidence.
In the digital world, this involves complex math and has uses like proving identity without sharing details, private computations, and secure communication. Benefits: privacy, security, no need for a third party. Challenges: complexity, user-friendliness, but improving.
