An overview of the cluster mempool proposal

The discussion raises a crucial concern regarding the potential for a new attack vector stemming from the significant effort needed to reject a Replacement By Fee (RBF) transaction. This issue highlights the necessity for thorough analysis and understanding of the implications such actions might have on system security and integrity. The consideration of this aspect is critical in ensuring that systems are robust against various forms of attacks, including those that may exploit the RBF mechanism. It prompts a deeper examination of how RBF transactions are handled and the safeguards that need to be in place to mitigate any associated risks.
