Andrew C questioned why they would wait so long to publish it and suggested publishing it a few days after the final alert instead. However, another participant in the discussion responded that they needed to ensure the revocation message was widely distributed before making the private key public.The context of this conversation is unclear, but it is likely related to discussions around potential security vulnerabilities in the Bitcoin network. There are several possible reasons why Lau may have suggested waiting to publish the key. One explanation could be that it allows time for any remaining users who have not updated their software to do so before the key is made public. Another possibility is that it gives developers time to create patches or other solutions to address any issues that may arise after the alert is disabled. Additionally, waiting a few months could help ensure that all nodes on the network have had a chance to disable the alert and are no longer affected by its presence.Bitcoin Core has removed the alert system, which was a centralized facility that allowed trusted parties to send messages to be displayed in wallet software and remotely trigger the software to stop transacting. The system had some potential uses but also had issues that made it problematic. It was a frequent source of misunderstanding about the security model and effective governance. Furthermore, the system was not scalable to different software vendors, and no one could tell who created a message. Additionally, there was good reason to believe that the key was compromised. Due to these issues, the alert system has been deactivated, and Gregory Maxwell via Bitcoin-dev plans to send a triggering alert in the future and disclose the private key in public to eliminate any further potential of reputation attacks and diminish the risk of misunderstanding the key as some special trusted source of authority.Overall, the email chain and discussions highlight the importance of careful planning and communication when it comes to managing security risks in complex systems like Bitcoin. It is crucial to address potential vulnerabilities and ensure the widespread distribution of important messages before implementing changes or disclosing sensitive information. The removal of the alert system and the plans for deactivating the key demonstrate a proactive approach to protecting the integrity and reputation of the Bitcoin network.
