SonoCoin claims to be the first blockchain network to transact via encrypted audio files. The coin's .WAV file format gives anyone the power to transact using simple methods of delivery such as sound (similar to Shazam), messenger, QR and Bluetooth. SonoCoin’s blockchain platform is a “b-to-b-to-c” (b2b2c) model, where SonoCoin licenses its platform to retailers, who in turn leverage the technology to increase sales and customer engagement. The transmission of SonoCoins while watching a television commercial can offer viewers rebates on displayed products similarly to eCoupons. This solution helps companies eliminate costly third parties, streamlining services for both the consumer and company in the digital marketing, loyalty programs, and gaming industries.
