Module aggregate 

Aggregate signatures for multi-peer coordination in CHIE protocol.

This module provides signature aggregation capabilities, allowing multiple peers to sign a message and combine their signatures into a compact representation.

Features

• Aggregate multiple signatures from different signers
• Batch verification of aggregated signatures
• Compact representation for network efficiency
• Built on Ed25519 for compatibility with existing infrastructure

Example

use chie_crypto::aggregate::{AggregateSignature, SignatureAggregator};
use chie_crypto::KeyPair;

// Multiple peers sign the same message
let message = b"bandwidth proof for chunk 123";

let keypair1 = KeyPair::generate();
let keypair2 = KeyPair::generate();
let keypair3 = KeyPair::generate();

let sig1 = keypair1.sign(message);
let sig2 = keypair2.sign(message);
let sig3 = keypair3.sign(message);

// Aggregate signatures
let mut aggregator = SignatureAggregator::new();
aggregator.add_signature(&keypair1.public_key(), &sig1);
aggregator.add_signature(&keypair2.public_key(), &sig2);
aggregator.add_signature(&keypair3.public_key(), &sig3);

let aggregate = aggregator.finalize(message).unwrap();

// Verify all signatures at once
assert!(aggregate.verify(message).is_ok());
