Vitalik proposed establishing a silent alarm system using secret voice commands to combat crimes targeting crypto holders.

PANews reported on March 13th that Ethereum founder Vitalik Buterin published an article on the X platform proposing a tool to enhance personal security and protect civil liberties at a low cost: everyone should have a simple and "repudiable" way to call for help. For example, pre-setting a few secret words that, when heard by a watch, phone, or home device, automatically and silently dial 911 and transmit the location to the police in real time. 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 will arrive immediately in the event of a robbery, and the robbers cannot detect whether an alarm has been triggered, then such crimes would be too risky to be feasible. Because this function requires active action from the victim, the risk of it being abused by governments for mass surveillance is relatively low.
