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.
