1. Chain Analysis Engine

Blockchain Event Processing Pipeline

The Chain Analysis Engine implements a sophisticated event processing pipeline utilizing asynchronous I/O patterns for real-time blockchain data ingestion. The system employs a multi-threaded architecture for parallel processing of transaction streams, with configurable batch sizes for optimal throughput.

PROCESSING_CONFIG = {
    'MAX_BLOCKS_PER_BATCH': 100,
    'PROCESSING_THREADS': 4,
    'CACHE_DURATION': 300,  # seconds
    'RPC_TIMEOUT': 10,
    'MAX_RETRIES': 3,
    'BACKOFF_FACTOR': 2
}

Transaction Pattern Recognition Systems

The transaction analyzer implements advanced graph-theoretic algorithms for detecting complex trading patterns. The system utilizes cyclomatic complexity analysis for identifying wash trading and artificial market manipulation patterns.

Key Pattern Detection Mechanisms:

PATTERN_DETECTION = {
    'stealth_accumulation': {
        'min_transactions': 5,
        'max_size_ratio': 0.1,
        'time_window': 3600
    },
    'distribution': {
        'min_transactions': 10,
        'min_unique_receivers': 5,
        'time_window': 7200
    },
    'wash_trading': {
        'min_cycle_length': 3,
        'max_time_between': 300,
        'min_volume': 1000
    }
}

Liquidity Flow Analysis Framework

The liquidity tracker implements real-time monitoring of DEX liquidity pools, utilizing advanced statistical methods for anomaly detection. The system employs custom algorithms for:

• Parkinson's High-Low Range Volatility Calculation

• Exponentially Weighted Moving Average (EWMA) for Volume Analysis

• Non-Parametric Kernel Density Estimation for Liquidity Distribution

Implementation example for liquidity impact calculation:

async def calculate_liquidity_impact(
    self,
    pool_data: Dict,
    volume: float,
    timeframe: int
) -> float:
    """Calculate market impact of liquidity changes.
    
    Args:
        pool_data: Current pool state
        volume: Transaction volume
        timeframe: Analysis timeframe in seconds
        
    Returns:
        Impact score between 0 and 1
    """
    try:
        # Calculate liquidity depth
        depth = await self._calculate_pool_depth(pool_data)
        
        # Normalize volume against pool depth
        volume_impact = min(1.0, volume / depth)
        
        # Calculate temporal factors
        temporal_impact = self._calculate_temporal_impact(
            pool_data['history'],
            timeframe
        )
        
        # Combined impact score with weights
        impact_score = (
            volume_impact * 0.7 +
            temporal_impact * 0.3
        )
        
        return float(impact_score)
        
    except Exception as e:
        logger.error(f"Error calculating liquidity impact: {e}")
        return 1.0  # Maximum impact on error

Performance Characteristics

The Chain Analysis Engine maintains the following performance metrics:

Throughput:
    Transactions/Second: 1000+
    Block Processing Delay: <100ms
    Event Propagation Latency: <50ms

Resource Utilization:
    Memory Footprint: ~2GB per instance
    CPU Utilization: 60-80% optimal
    Network Bandwidth: 100Mbps sustained

Scaling Capabilities:
    Horizontal Scaling: Up to 10 instances
    Load Distribution: Round-robin with sticky sessions
    Failover Time: <5 seconds

The system implements sophisticated error handling and retry mechanisms with exponential backoff strategies for RPC node interactions. Circuit breakers are implemented to prevent cascade failures during high-load scenarios.

Monitoring and Alerting

The engine provides comprehensive metrics through Prometheus endpoints:

Metrics:
    - blockchain_events_processed_total
    - transaction_analysis_duration_seconds
    - pattern_detection_success_rate
    - liquidity_impact_distribution
    - rpc_node_health_status

Alerts:
    - HighLatencyAlert: >100ms processing time
    - ErrorRateHigh: >1% error rate
    - NodeConnectionLost: RPC connection failure
    - PatternDetectionFailure: Algorithm errors

Integration with external monitoring systems is achieved through standardized metrics exposition and webhook notifications for critical events.
