According to CoinMeta, developers have shared their newly developed Android application BTCPuzScan, which is designed to help users find the private keys for ongoing Bitcoin puzzles. The application can run at a speed of scanning 2.5 million keys per second on their test devices and guarantees 100% accuracy. Users can test the application through an online cloud-based Android emulator without the need to install it on their phones. The developers stated that internet permissions have been removed from the application to ensure that even if private keys are found, they cannot be transmitted outside, thus safeguarding user security.
