Description
Batch multiple ZK proofs into a single aggregated proof for cost-efficient on-chain verification. Includes a Solidity batch verifier contract and a TypeScript aggregation service that collects proofs, builds Merkle trees of proof commitments, and submits batched verification transactions.
Features
- ✓ Proof aggregation via recursive SNARK composition
- ✓ Merkle tree commitment for proof batches
- ✓ Configurable batch size and submission intervals
- ✓ On-chain batch verifier contract
- ✓ TypeScript aggregation service with queue management
- ✓ Gas cost comparison: individual vs batched
- ✓ Retry logic for failed batch submissions
- ✓ Monitoring hooks for batch status tracking
- ✓ ReentrancyGuard on verification callbacks
- ✓ Full test suite for contracts and service
