Why Ev­ery­one’s Buzzing about Blockchain

Clean Eating - - A GREENER YOU -

The same tech­nol­ogy that is be­hind cryp­tocur­ren­cies like Bit­coin is com­ing to your pantry very soon, al­beit in a more be­hind-the-scenes way. Blockchain is a shared and tam­per-proof dig­i­tal ledger, which al­lows re­tail­ers, such as Wal­mart, to show and track their supply chains. In the process, they are hop­ing to gar­ner con­sumer trust as well as min­i­mize waste. Mo­bile apps pick up real-time in­for­ma­tion through sen­sors and cam­eras or al­low farm work­ers across the chain to quickly en­ter data in one uni­fied place, thus re­plac­ing the time­lagged sys­tem of pa­per­work, bar­codes and com­puter pro­grams of yore. The goal? To help re­tail­ers and grow­ers gain more real-time in­sights and con­fi­dence about ev­ery point in the food sys­tem.

Test­ing has shown that blockchain can pro­vide a more com­plete pic­ture in real time

of food’s jour­ney, which ex­perts hope may help slash food re­call and con­tam­i­na­tion, re­duce food waste and fight food fraud. In one re­cent test case, blockchain al­lowed Wal­mart to trace a batch of man­gos in a mat­ter of mo­ments (2.2 sec­onds) back to the ex­act or­chard in Mex­ico

– ver­sus 63∕4 days from tra­di­tion­ally used meth­ods.
