Understanding Zero-knowledge proofs through simple examples

I recently listened to this ZKFM podcast, which gave practical examples that clearly explained key concepts in zero knowledge. I felt inspired to transcribe them here. In cryptography, zero knowledge proofs let you convince me that you know something, or have done something, without revealing to me what your secret thing was. Practically, zero-knowledge is important because it gives you privacy in
