[Vitalik Proposes 'Silent Alarm' Tool: Trigger Silent Alerts with Pre-set Code Words to Enhance Crypto Holder Security] Foresight News reports that Vitalik Buterin suggested a low-cost, high-security tool in a Warpcast post. Users can pre-set several secret code words, and when a smartwatch, phone, or home device hears these words, it will automatically and silently call 911, transmitting the location to the police in real time. This tool requires no explicit operation and only activates when the victim intentionally speaks the code word. This is particularly effective for crypto holders worried about kidnapping or robbery: robberies would become highly unprofitable, significantly increasing the cost of committing such crimes.
