Blockchain-Based AI Voice Assistant Brings Data Privacy To Smart Homes

According to a 2017 University of Washington report, there are hundreds of millions of smart-home devices in more than 40 million U.S. homes. This number is expected to double by 2021. Amazon Echo, Google Home and other devices that have Alexa and Google Assistant built in, have proven to be some of the world's most promising new technologies. These AI-enabled assistants seem capable of doing everything, from turning on lights to answering simple and even complex questions. "OK Google" and "Alexa" have become common household phrases, as these smart connected speakers always have their microphones on, yet don't respond until their "wake words" are mentioned.
