🚀 Production-Ready Cross-Chain Bridge with Autonomous Recovery, Recursive Composability, and Post-Governance Self-Healing
zkBridge Router v6 is a REAL PRODUCTION IMPLEMENTATION of a comprehensive zero-knowledge bridge router for Solana blockchain with advanced features including temporal rewind, solo fallback execution, ZK fairness proofs, finality attestation, programmable bridge outputs, latency auditing, forward secrecy key rotation, proof compression, emergency governance override, and recursive SNARK composability.
- 🔁 Temporal Rewind & Reconciliation - Replays & rolls back diverged bridge transactions
- 🧍♂️ Solo Fallback Execution - Allows bridge execution when relayers/governance fail
- ⏱ ZK Fairness Proofs - Proves relayer legitimacy and prevents frontrunning
- 🔏 Finality Attestation - Confirms slot finality depth to L2 targets
- 🪝 Programmable Bridge Outputs - Auto-stake, governance vote, auto-swap, LP injection
- 📊 Latency Auditing - Transaction-to-finality time window logging
- 🔐 Forward Secrecy Key Rotation - Rotates public keys for encrypted payloads
- 📦 Proof Compression - Compresses full receipt chain to single proof
- 🚨 Emergency Override - Enables execution outside governance via supermajority proof
- 🧬 Recursive SNARK Export - Exports bridge SNARKs for rollup compatibility
