[Vitalik Proposes Secret Voice Command Silent Alarm System to Combat Crimes Targeting Crypto Holders] Ethereum founder Vitalik Buterin posted on the X platform, proposing a tool to enhance personal safety and provide a low-cost safeguard for civil liberties. He suggested that everyone should have a simple and 'deniable' way to trigger an alarm. For example, by pre-setting a few secret keywords, when a smartwatch, smartphone, or home device hears these words, it would automatically and silently dial 911 and transmit the real-time location to the police. This would be particularly effective for cryptocurrency holders worried about kidnapping or robbery. Vitalik stated that if the environment ensures at least a 20% probability that the police would arrive immediately during a robbery, and the robbers cannot detect whether the alarm has been triggered, such crimes would become unfeasible due to the high risk. Since this feature requires the victim to take active steps to operate, the risk of it being abused by governments for mass surveillance is relatively low.
