IBM unveils world's smallest computer that's tinier than a grain of salt

This device is a part of IMB Research's 5 in 5 project announced at the event. As the name suggests, this project is about IBM's Research team working on five technologies based on Artificial Intelligence (AI), blockchain, encryption and Internet of Things (IoT). All these technologies are clubbed under crypto-anchors based on blockchain technology.

These crypto-anchors can take the form of tiny computers or optical codes which can be embedded into products. IBM says that the purpose of these crypto-anchors is to help eliminate counterfeit products which are widespread globally. Crypto-anchors can be embedded into something as small as "an edible shade of magnetic ink". Also, crypto-anchors are considered "highly secure" which cannot be cloned.
