Conversation
- Implemented a Transaction Monitor in Rust to observe transaction flow between nodes. - Created a multi-node simulation script to manage multiple node instances for testing. - Developed a simulation manager script for easy command execution of various simulation scenarios. - Added a simulation API for handling transaction requests and node status checks. - Enhanced logging and output for better monitoring and debugging during simulations.
…orus - Added new documentation for multi-node transaction simulation and complete propagation. - Created scripts for multi-node simulation, complete transaction propagation simulation, and testing complete propagation. - Enhanced the existing simulation script to manage multiple node instances and handle transaction sending and receiving. - Introduced a new monitoring script to observe transaction propagation in real-time. - Implemented detailed logging and error handling for transaction status reporting. - Updated configuration files for nodes to support new features and ensure proper operation.
…lity and consistency - Organized imports in `multi_node_simulation.rs` and `transaction_monitor.rs` - Removed unnecessary whitespace and comments for clarity - Enhanced logging messages for better transaction tracking in `simulation_api.rs` - Standardized function signatures and formatting in `cli.rs` and `simulation_api.rs` - Improved overall structure and formatting in various modules for better maintainability

There appears to be stray or incomplete text ('SIM') that should be removed or corrected to avoid confusion in the backup script.

[nitpick] Duplicate transaction status reporting logic is detected; consider removing the redundant block to simplify the script.
