Cross-Chain Proof Relay

🌐 Cross-Chain Proof Relay

The Proof Relay is the bridge component that transfers zero-knowledge proofs across chains.

🚚 Responsibilities

Task	Description
Proof Transport	Moves proofs between Zcash and ETH/BSC layers.
Nonce & Replay Guard	Ensures proofs cannot be replayed.
Gas-Optimized Batching	Batches proofs to lower relay costs.

🔑 Security Guarantees

• Messages are signed and hashed before transmission.

• Relay does not have the ability to mint or move funds.

• If relay fails → funds remain safe in Zcash Layer by default.

📦 Technical Implementation

• Based on Merkle tree state commitments

• With stateless light-client verification
