Could these grain-sized computers using blockchain networks thwart counterfeiters?

Within five years, IBM researchers hope to deploy granular microcomputers that, in conjunction with a blockchain electronic ledger, could be used to verify and track goods all over the world.

IBM has created a microcomputer technology called cryptographic anchors (abbreviated: crypto-anchors) and says they could be used to authenticate anything from pharmaceuticals to luxury goods, such as diamonds, from point of origin to merchant.
