SonoCoin is a technology company that developed a protocol for transmitting data over sound waves, enabling devices to connect and transact even without traditional internet connectivity. The project created its own cryptocurrency, the SONO coin, which was intended to facilitate these data transfers and transactions, particularly for IoT (Internet of Things) applications and offline payments. The company's mission was to create a new layer of connectivity and a universally applicable crypto-payment system, though development and public communication appear to have ceased around 2019.
