One Chinese startup wants to build a blockchain toothbrush to mine coins while you clean your teeth

One Chinese company says they’re developing a toothbrush to let you mine coins while cleaning your pearly whites. And if you’re not impressed by 32Teeth’s idea, they threw in another two buzzwords too: They claim it will also use facial recognition and augmented reality.

(In case you’re wondering how a toothbrush can see your face or use augmented reality, that part is in the companion app.)

Given that the project is still at the crowdfunding stage -- and the idea seems rather odd -- it’s hard not to be suspicious. But some companies say there are benefits to integrating blockchain with household devices.
