The suggestion to iterate through an "orphanage," in addition to the existing "vextra buffer," highlights a strategic approach to enhance the efficiency of transaction processing. However, the effectiveness of incorporating orphans directly into blocks is questioned due to the inherent necessity of including parent transactions for completeness and integrity.

Further exploration into improving the mechanism of populating "prefilledtxns" is proposed. This involves preemptively identifying transactions that peers are likely unaware of and transmitting these transactions immediately, potentially reducing the need for additional communication rounds to acquire missing information. This proactive strategy aims to streamline the process by which transactions are shared among peers, ensuring a more efficient distribution of data.

Additionally, there is a consideration toward updating and utilizing the FIBRE patch set, coupled with the reinstatement of public servers. This approach suggests leveraging existing technological solutions and infrastructure enhancements to address the challenges faced. By focusing on these updates and infrastructure improvements, there may be significant opportunities to optimize the overall system's performance and reliability, thereby mitigating the issues associated with handling orphan transactions and enhancing the network's efficiency.
