Wal-Mart has described its recent pilots with blockchain, a technology that aims to increase traceability and transparency in the supply chain, as “very encouraging.”

The retail giant has been testing the system with pork in China and mangoes in the U.S., according to a recent update from the company. Farm origination details, batch numbers, factory and processing data, expiration dates and shipping detail are among the data being recorded.

Wal-Mart has said the system can dramatically speed up the process of tracing a food item, from days to seconds, allowing for faster and more targeted recalls. Blockchain also serves as a digital home for audits, certificates and other documentation, ideally streamlining compliance.

With more consumers wanting to know about the path their food traveled to reach them, the technology may also be useful in being able to communicate to those interested about each stop along the supply chain for any particular item.

Wal-Mart is working with IBM on the project and plans to continue with its testing, according to the update.
