Module pedersen 

Pedersen commitments for privacy-preserving bandwidth proof aggregation.

This module provides Pedersen commitments with homomorphic properties, enabling privacy-preserving aggregation of bandwidth proofs in the CHIE protocol.

Features

• Homomorphic commitments: C(a) + C(b) = C(a+b)
• Privacy-preserving bandwidth aggregation
• Commitment verification without revealing values
• Batch commitment operations

Example

use chie_crypto::pedersen::{PedersenCommitment, commit, verify};

// Commit to bandwidth values
let (commitment1, opening1) = commit(100);  // 100 bytes
let (commitment2, opening2) = commit(200);  // 200 bytes

// Aggregate commitments
let aggregated = commitment1.add(&commitment2);
let aggregated_opening = opening1.add(&opening2);

// Verify aggregated commitment (300 bytes total)
assert!(verify(&aggregated, 300, &aggregated_opening));
