For a long time there was a popular trick among cheaters to get a new smartphone: they first looked for a used and no longer working device. Then they ordered the same model again at Amazon - and finally returned the second-hand phone. In the meantime, the online giant has prevented this possibility, but it is clear: tracking a specific product along the supply chain is not so easy. The Vechain Coin wants to make this possible now with the help of the Blockchain. The big advantage: once stored data can not be manipulated. With the help of a chip, each product can be safely identified and tracked.
