Architecture Overview

The transaction validation system consists of several key components:

Core Components

1. Transaction Validator

   • Handles the main validation logic
   • Manages validation rules
   • Processes transaction data

2. Rule Engine

   • Applies validation rules
   • Supports custom rule creation
   • Manages rule priorities

3. Network Interface

   • Manages blockchain connections
   • Handles RPC calls
   • Implements retry logic

Implementation Details

Validation Process

1. Initial Validation

   transaction -> Parse -> Validate Signature -> Check Format
   

2. Chain Validation

   validate chain state -> check balance -> verify permissions
   

3. Final Verification

   verify execution -> confirm state changes
   

Error Handling

• Custom error types for different validation failures
• Detailed error messages and codes
• Automatic retry for transient failures

Performance Optimization

• Caching of frequently accessed data
• Batch processing capabilities
• Parallel validation where possible

Security Considerations

1. Input Validation
2. Rate Limiting
3. Access Control
4. Error Handling
5. Data Validation

Testing Strategy

• Unit Tests
• Integration Tests
• Performance Tests
• Security Tests
