Stats on compact block reconstructions

By analyzing the statistics from various nodes, it becomes evident that the efficiency of block reconstructions significantly depends on the node's ability to prefill transactions in the compact block, utilize transactions from its mempool, and draw from an extra pool when necessary. The analysis highlights periods where the need for additional transaction requests was notably high, coinciding with increased mempool sizes. This suggests a direct correlation between mempool activity and the efficiency of block reconstructions.

Adjustments made to node configurations during the observation period, such as increasing maximum connections or adopting mempoolfullrbf=1, appear to have tangible effects on the rate of compact block reconstructions that do not require additional transaction requests. Particularly, the shift towards enabling mempoolfullrbf by default is posited as a strategy to potentially enhance block reconstruction efficiency across the network, indicating a reevaluation of default Bitcoin Core policies might be beneficial for network-wide block propagation times.

Furthermore, the investigation points out significant disparities in median block reconstruction duration, especially between scenarios requiring transaction requests and those that do not. This variance underscores the impact of network congestion and node configuration on the blockchain's operational efficiency. The inquiry also opens up avenues for further research, such as examining the role of extra transactions in low- versus high-bandwidth block reconstructions and understanding how different extra pool sizes affect reconstruction efficiency.

By delving into these aspects, the discussion illuminates the complex balance between maintaining network security, ensuring efficient data propagation, and optimizing system resources. It encapsulates the ongoing efforts within the cryptocurrency community to refine and improve the underlying mechanisms of blockchain technology, striving for a more robust, efficient, and scalable network infrastructure.
