+//! Chaum-Pedersen Proof Example
+//!
+//! This example demonstrates a Chaum-Pedersen proof, which proves equality of discrete
+//! logarithms across two different bases. Given public values g1, g2, h1, h2,
+//! the prover demonstrates knowledge of a secret x such that:
+//!   h1 = g1^x  AND  h2 = g2^x
+//!
+//! This proof is useful in many cryptographic protocols, including:
+//! - Proving correct re-encryption in ElGamal
+//! - Verifiable shuffles
+//! - Threshold cryptography
+//!
+//! The implementation uses Ristretto255, a prime-order group built on Curve25519.
