The ledgers are safeguarding the tracking of veggies, drivers, home keys
TOKYO — The blockchain is said to be bitcoin’s big technological innovation. Think of it as a public, digital, ever-growing ledger that tracks all transactions made with the cryptocurrency and, essentially, vouches for the currency. Now the innovation is being adopted by Japanese agriculture and other sectors.
Osaka-based venture Sivira has established a system in which multiple computers can share and record information regarding vegetables produced in Aya, in the southwestern prefecture of Miyazaki. The records are blockchained together against modification, thereby ensuring that consumers get accurate data on the produce they buy.
For instance, when a shopper buys a package of eggplant, often used in Asian curries, he or she would be able to look at a long set of data, including the farmer’s name, kinds of fertilizers used, planting time as well as the date and time of day the vegetables were delivered to a neighborhood store.
Consumers can access these chronological ledgers by using their smartphones to scan QR codes on packaging.
