Understanding Zero-Knowledge Proofs Zero-Knowledge Proofs (ZKPs), a cryptographic protocol, allow one party (the prover) to confirm the truth of a statement to another party (the verifier) without revealing any additional information about it. First proposed by researchers from the Massachusetts Institute of Technology (MIT) - Shafi Goldwasser, Silvio Micali, and Charles Rackoff in their 1985 paper on "The Knowledge Complexity of Interactive Proof Systems." How It Works Imagine being in a room with a blindfolded person and two balls on the table—one white and one black. You need to prove to the blindfolded person (verifier) that the balls are truly different colors without revealing which ones. You ask them to hide both balls under the table, then show one. You can prove the claim because you know if they swapped the balls under the table. However, the verifier isn't completely certain, considering luck or deception. This uncertainty diminishes with each repetition. After...
