- * Shared deny list manager providing single source of truth for deny list state.
+ * Shared deny list manager that uses gRPC to communicate with the RLN prover's database.
*
- *
This manager encapsulates all deny list functionality including:
+ *
This manager provides a unified deny list that is shared between the sequencer and RLN prover,
+ * backed by the prover's PostgreSQL database.
*
- *
- * - Thread-safe in-memory cache management
- *
- Atomic file I/O operations with proper locking
- *
- Automatic TTL-based entry expiration
- *
- Scheduled file refresh for external modifications
- *
- Clear separation of read-only vs write operations
- *
- *
- * Usage Pattern:
+ *
Features:
*
*
- * - RlnVerifierValidator: Uses both read and write operations
- *
- LineaEstimateGas: Uses only read operations for efficiency
+ *
- gRPC-based communication with the RLN prover service
+ *
- Local in-memory cache for read performance
+ *
- Automatic cache refresh from database
+ *
- Graceful fallback to cache if gRPC is unavailable
+ *
- TTL-based entry expiration (handled by the database)
*
*
- * Thread Safety: All operations are thread-safe using ConcurrentHashMap and
- * synchronized file I/O.
+ *
Thread Safety: All operations are thread-safe using ConcurrentHashMap for the

/**
- * High-performance nullifier tracking service using Caffeine cache.
+ * High-performance nullifier tracking with database persistence via gRPC.
+ *
+ *
Architecture: Uses a two-tier approach for maximum performance:
+ *
+ *
+ * - Hot path: Local in-memory cache (Caffeine) for O(1) duplicate rejection
+ *
- Cold path: PostgreSQL database via gRPC for persistence and cross-instance sharing
+ *
*
* Security Critical: This component is essential for RLN security. Nullifier
* tracking prevents replay attacks and enforces transaction rate limiting by detecting when users
* reuse nullifiers within the same epoch.
*
- *
Performance Optimized: Uses Caffeine cache for high-throughput, low-latency
- * operations. Eliminates file I/O bottlenecks present in naive implementations.
- *
- *
Epoch Scoping: Nullifiers are tracked per epoch. The same nullifier can be
- * reused across different epochs but not within the same epoch, enabling proper rate limiting.
- *
- *
Automatic Cleanup: Expired nullifiers are automatically evicted based on
- * configured TTL to prevent unbounded memory growth.
+ *
Performance Target: 500+ TPS with sub-millisecond response times for
+ * duplicate detection.
*
- *
Thread Safety: All operations are thread-safe and lock-free, suitable for
- * high-concurrency transaction validation.
