Can technology trace the origin of the cotton fabric you are wearing, down to the farmer? The answer is yes. With blockchain technology, it is now possible to trace cotton fabric down to the fundamental level of raw materials or crop, and ensure transparency that the final product is actually 'organic'. Cotton is the most widely used fabric all over the world and accounts for over 40 percent of the total global fiber production. To meet this demand, farmers use high-yielding genetically modified plants, with excessive pesticides and fertilizers. The crop pollutes the environment and the end products are full of chemicals and can cause allergic skin reactions.
