Read OriginalThis article provides a beginner-friendly, non-technical explanation of the core concept behind public key cryptography. It uses the analogy of the 'Ali Baba and the Forty Thieves' story to illustrate the problem of proving you know a secret (like a password) without revealing it to eavesdroppers, and introduces a simple number-based game to build intuition for how this is achieved in digital systems like blockchain.
