The world’s smallest computer
A grain of salt—that’s the size equivalent of the world’s smallest computer, a less than 1mm x 1mm chip that will cost 10 cents to produce. Recently unveiled at Think 2018, the computer consists of a processor with several hundred thousand transistors, SRAM memory, a photo-voltaic cell for power, and a communications unit that uses an LED and a photo-detector. While there are countless potential applications, the computer is initially being developed to combat counterfeiting: its size makes it an ideal crypto-anchor—which, combined with blockchain technology, will create an immutable seal of authenticity—within supply chains.
