The software behind the cryptocurrency bitcoin has found an unlikely use – stopping counterfeit drugs. Using edible barcodes and a blockchain, TruTag Technologies, based in Hawaii, believes it can track cannabis sold legally in the US.
The firm tags cannabis edibles, such as brownies or lollipops, with tiny silica particles described as edible barcodes. The idea is that these barcodes are very difficult to imitate and can be scanned to reveal that a particular product is legitimate.
