bnb-chain/bsc v1.5.18 | Chain Release Info

This release delivers significant performance enhancements, validator-focused MEV improvements, and streamlined node management features.

Key Highlights

Enhanced MEV Blind Bidding for Validators
To better serve validators' interests, the MEV auction is now truly blind. The system no longer reveals the current best bid price through RPC methods or in bid rejection messages. This change incentivizes builders to submit their best possible bid upfront, which is expected to increase validator revenue. Additionally, default MEV configuration values have been fine-tuned for better performance.

Performance and Database Optimizations
This version includes several key improvements to boost node performance and stability:

Shared Storage Pool Re-enabled: A bug has been fixed and the shared storage pool feature has been re-enabled, providing a performance improvement of approximately 4%. Node operators can activate it with the flag --cache.enablesharedpool.
Pebble DB Compaction Tuning: The database compaction parameters have been adjusted to trigger more frequently. This significantly reduces accumulated DB "debt", leading to smoother I/O operations and better overall execution performance.
Inefficient Cache Removed: An internal Keccak256 hash cache was found to be decreasing performance and has been removed, resulting in a net performance gain.

Node Operations and P2P Improvements

Modernized Block Pruning: The outdated prune-block and pruneancient tools have been removed. They are replaced by a more efficient online pruning mechanism managed by the --history.blocks flag, which uses tail-deletion. The node will automatically detect and migrate configurations from the legacy tools.
Improved EVN Connectivity: To resolve connection issues, Executor Validator Node (EVN) peers are now automatically treated as trusted nodes, ensuring more stable and reliable P2P connections between them.
Database Simplification: When using the --multidatabase mode, only trie-related data will now be separated into a different database. The blockstore will no longer be split, as this was found to increase complexity without providing performance benefits.

Bug Fixes and Other Improvements

A fix has been implemented to prevent log spam that occurred when recommitting MEV bids under certain error conditions.
The build process has been updated to use Go 1.24.
Nodes running an outdated version will now see a warning, prompting them to upgrade before the next hard fork.
