Combined summary - How was the average size of blk*.data chosen?

The determination of file sizes for storing data on blockchain networks is a critical decision influenced by various technical considerations to ensure optimal performance and compatibility.

For instance, the Monero cryptocurrency stores all block data in a single file, which poses challenges when dealing with older file systems that do not support files larger than 4GB. This limitation necessitates selecting a maximum file size below this threshold to avoid issues such as difficulties in copying files between locations. Additionally, storing an excessive number of files within a single directory can lead to operational problems, suggesting a balance must be struck between the number of files and their individual sizes.

The Bitcoin network adopts a structured approach to data storage through its blk*.dat files, which encapsulate raw block data including verified transactions. These files are generated sequentially and maintain a consistent size range between 128MB to 134MB. This size specification results from meticulous testing aimed at optimizing various aspects of system performance such as efficiency in read/write operations and synchronization speeds with the network. The underlying rationale is to achieve a balance that minimizes the number of read/write operations—thereby enhancing performance—while also ensuring files are not so large as to impede download and processing times, which could slow down synchronization with the blockchain.

Developers conduct extensive benchmark tests to ascertain the impact of file size on the blockchain's overall performance, examining factors like synchronization times and system responsiveness during read/write processes. Such experimentation is vital for maintaining the efficiency and scalability of the Bitcoin software, enabling it to handle growing transaction volumes without significant performance loss. The chosen file size has direct implications for users operating full nodes, affecting the required disk space and the speed at which nodes can fully synchronize with the network. As the blockchain continues to expand, ongoing adjustments and monitoring by developers are essential to keep the Bitcoin network resilient and accessible.
