Blockchain’s Latest Triumph: Mango Tracking

Do you know where these mangoes are from? Probably not, thanks to your primitive recordkeeping. But if you had blockchain, you'd know in 2.2 seconds!Momen Faiz/NurPhoto via ZUMA

This morning the LA Times greets me with this headline:

Could blockchain have solved the mystery of the romaine lettuce E. coli outbreak?

Blockchain will get us to Mars! It will cure cancer! It will tell us where our lettuce came from! And not just lettuce:

Take mangoes. The increasingly popular fruit grows on small farms scattered across Latin America, and can harbor listeria, a bacterium that kills 260 people per year in the U.S., according to the Centers for Disease Control and Prevention. Two years ago, [Frank] Yiannas told his staff to trace a packet of sliced mango from a Walmart aisle the traditional way. “I looked at my clock and wrote down the time and date, and I timed them,” he said. “It took them six days, 18 hours and 26 minutes.”

But with Walmart’s new IBM blockchain-enabled system, Yiannas tracked the mango in 2.2 seconds!

This is ridiculous. The problem, as the article makes clear, is that right now a lot of this recordkeeping is done on paper. To speed it up you need to computerize everything in a common format, which is what IBM did. In other words, the reason Yiannas could perform a trackback test in 2.2 seconds has nothing to do with blockchain and everything to do with “cooperative partners agreeing on what information to contribute.”

That’s called EDI, and it’s been around since the 70s. To make it work, all you need is (a) agreement from every single person in your supply chain about how to encode the data, and (b) agreement from every single person in your supply chain to computerize their records using the appropriate ANSI standard. Using blockchain as one of the underlying encoding formats is an architectural choice, but there are dozens that probably work just as well. The hard part isn’t the formatting, it’s getting everyone to computerize their records.

But it’s blockchain! Whoop!

In-depth journalism that investigates the powerful takes real money and is so damn important right now.But it doesn’t take a Mother Jones investigation to know that billionaires and corporations will never fund the type of reporting (like they do politicians) we do that exists to help bring about change. Instead, our mission-driven journalism is made possible by people power, and has been for 46 years now since our founding as a non-profit.

In “TITLE TK” Monica Bauerlein writes about the perilous moment we’re in, and why it’s so important that we raise $325,000 by the time November’s midterms are decided so we can be ready to throw everything we have at the big issues facing the nation no matter what happens.
