    • Streamlined the initialization of GRIDNET Core’s internal autonomous firewall sub-system, significantly boosting DDOS mitigation performance through integration with Kernel Mode Firewall modules of native operating systems.
    • Updated the firewall GridScript utility to support enabling and disabling of the kernel mode firewall integration, offering Operators refined control over security configurations.

Networking and Protocol Integration

  • QUIC Protocol Preference: Solidified QUIC as the preferred communication protocol, underlining our commitment to utilizing advanced technologies for optimal network performance.

  • Connection Management and Scheduling:

    • Implemented a more aggressive connection scheduling algorithm, particularly with Tier 0 nodes, optimizing network throughput and stability.
    • Addressed and resolved an issue leading to an excessive number of connections being established with remote nodes over short periods, enhancing network efficiency.

System and Protocol Optimizations

  • P2P Peer-Discovery and Bootstrapping: Enhanced the P2P peer-discovery subsystem by moving its initialization to a separate thread, mitigating impacts on the bootstrapping process and ensuring smoother network integration.

  • Connection Scheduling: Further improvements to the scheduling of connections have been made, optimizing network reliability and performance. This includes a refined approach to managing network traffic, ensuring that connections are more efficiently utilized and prioritized.

  • Firewall and Security Enhancements:

    • The firewall -list blocked command now provides insights into which entries are active or stale, offering Operators a clearer view of firewall rules and enhancing network security management.
    • Ensured that connections from (localhost) are always allowed and not subjected to throttling by the internal firewall, maintaining essential system access without compromising security.
    • Advanced integration of the GRIDNET Core autonomous internet firewall with the Kernel Mode Firewall module of the native operating system has been implemented, significantly enhancing DDOS mitigation capabilities.
  • Time Standardization: All instances of Core now return time in UTC, standardizing time reporting across the system and simplifying time management and event tracking.

  • Local IP Address Handling: Integrated firewall mechanics have been optimized to not trigger for ‘local’ IP addresses, streamlining system operations and reducing unnecessary firewall activations.

Network and Infrastructure Adjustments

  • Bootstrap Node Management: Conducted a review and removal of specific bootstrap nodes, including the node, as part of our ongoing network optimization efforts. This reflects our commitment to maintaining a robust and efficient network infrastructure.

Logging and Monitoring Enhancements

  • Improved Logging for Connection Issues: Logging functionality has been enhanced to provide more detailed information regarding broken connections, indicating whether issues occurred during transmission or reception of data. This enhancement aids in more precise troubleshooting and system monitoring.

  • DDOS Handling Over UDT Layer: Improvements have been made in handling DDOS attacks over the UDT layer, reinforcing the resilience of our network against such threats and ensuring uninterrupted service.

Cryptocurrency and Transaction Management

  • Memory Pool Management: Significant changes have been implemented in memory pool management to improve the handling of transactions associated with nonces. Transactions with a nonce value higher than expected are now cached until a suitable transaction with the preceding nonce value is processed. This enhancement aims to improve the overall Liveness property of the system.

  • New Memory Pool Sorting Algorithm: Introduced a new ‘feesHighestFirstNonce’ memory pool sorting algorithm, prioritizing transactions based on fees in a descending order and then by nonce value in ascending order for transactions with the same fee from the same account. This update optimizes transaction processing efficiency.

RESTful API Enhancements

  • Comprehensive Block Information: The getBlock RESTful function has been enhanced to include all transactions within a block and provide byte-code decompilation of these transactions into their GridScript human-readable representation, greatly aiding in transparency and analysis.

  • Enhanced Transaction Insights: The getTX RESTful API function now includes a wealth of information about transactions, such as the full decompiled source code (if the decompile argument is set), ERG Limit, nonce value, and both confirmed and unconfirmed timestamps in human-readable UTC format. This facilitates deeper insight and tracking of transaction states.

  • Account Balance and Nonce Value: The getBalance function has been updated to return the nonce value associated with the account, alongside the balance. This addition supports better account management and transaction tracking.

  • Broadcasting GridScript Code: A new RESTful function for broadcasting arbitrary GridScript code has been implemented, allowing for a single transaction to target an arbitrary number of recipients. This feature opens up new possibilities for decentralized application development and interaction within the GRIDNET ecosystem.

Keychain and Identity Management

  • Keychain Utility Enhancements: The keychain utility has seen significant improvements, including the change from keychain -nextid to keychain -genid, streamlining identity management within GRIDNET OS. For detailed guidance on utilizing the new features, Operators are directed to the comprehensive documentation available on our community forum.
