Re: [Opt-in full-RBF] Zero-conf apps in immediate danger

The discussion focuses on a significant change in the Bitcoin network, specifically the update in version 28.0 where the default setting for mempoolfullrbf was altered from false to true. This alteration is noteworthy due to its potential impact on the network's operation and participants. The fact that approximately 30%-40% of the network has reportedly adopted this version as of October last year underscores the relevance of this change. Furthermore, there is an interest in understanding the implications of this update on various fronts. These include the volume of bitcoin and lightning payments, customer satisfaction levels—especially in relation to any delays in payment acceptance—and the extent of engineering or support efforts required to accommodate this change. The inquiry seeks to gather insights or updates on these aspects to gauge the overall impact of the mempoolfullrbf default change on the network and its users.
