A Pull Request (PR) has been submitted for consideration, signifying a strategic move towards parallelizing certain operations that have traditionally been executed in a sequential manner. This PR, accessible via GitHub, proposes modifications to the current process by introducing the capability to fetch inputs from the disk concurrently.

This modification is poised to potentially streamline operations within the Bitcoin protocol, addressing efficiency and performance bottlenecks by leveraging parallel processing. By fetching inputs in parallel, the time taken for these operations could be significantly reduced, thereby enhancing the overall throughput and responsiveness of the system. This initiative reflects a broader trend within the development community, focusing on optimizing core aspects of Bitcoin's infrastructure to accommodate growing demands and complexities.
