Sharing block templates

The email discusses concerns and clarifications regarding a proposal related to Bitcoin transaction handling. The sender addresses an issue by highlighting the misconception that employing a template per peer creates an attack surface similar to existing ones, but with added complications. This misunderstanding suggests that using such a template would allow a miner to unduly influence the transaction database in the same manner as current methods, which the sender refutes. They argue that it's unlikely the person behind the original proposal, referred to as AJ, hadn't considered this aspect.

The proposition under discussion involves maintaining a separate template for each peer connected to a network, as detailed in a commit found at this GitHub link. This approach aims to mitigate the risk of a single peer being able to evict transactions from other peers' views of the transaction database. Instead, the worst a malicious peer could do is to consume a finite amount of memory without affecting the transactions of others. This method represents a strategic move to enhance the robustness of transaction handling within the Bitcoin network by ensuring that no single peer can disproportionately impact the visibility or handling of transactions across the network.
