The new prototype device, which is fully standalone, is composed of several hundred thousand transistors, a live memory, and a photovoltaic power supply. And it not only features a tiny form factor, its production cost, of around 10 cents per unit according to IBM, is also minuscule. The device was unveiled at IBM’s Think 2018 conference.

Not surprisingly the devices will not offer exceptional performance, but will be sufficient to record blockchain data to combat fraud. The goal is to attach them to tags, or even insert them into products, so that they can prove authenticity and record tracking information.
