Provider-Agnostic Blockchain Anchoring for Moloch.

This crate provides a unified interface for anchoring Moloch chain state to external blockchains (Bitcoin, Ethereum, Solana, etc.) without coupling to any specific implementation.

Example

use moloch_anchor::{AnchorManager, Commitment, MockProvider};

// Create manager with mock provider for testing
let mut manager = AnchorManager::new();
manager.register_provider(MockProvider::new("test"));

// Create a commitment to anchor
let commitment = Commitment::new(mmr_root, height);

// Anchor to all registered providers
let anchors = manager.anchor(&commitment).await?;

// Verify an anchor proof
let valid = manager.verify(&anchor_proof).await?;
