HÀ NỘI — Three big Thailand-based agriculture groups on Wednesday signed a memorandum of understanding (MoU) with Vietnamese LINA Network to apply blockchain to make the source and quality of products transparent.

The three are ChokChai, SAP Siam Food International and AIM Thai.

Under the MoU, ChokChai Group — the largest dairy cow breeding group in Southeast Asia — will apply LINA Network into its dairy production and supply lines. SAP Siam Food International Co Ltd and AIM THAI Group will use the application to follow products processed from fruits.

Speaking at the signing ceremony, Vũ Trường Ca, chairman of the management board of LINA Network, said Lina Supply Chain has been part of the blockchain ecosystem along with suppliers and customers.

The ecosystem was built based on Ethereum Blockchain, which has been the most popular and easy-to-use blockchain, to allow users to follow the source of a certain product in a real time.

Ca said the application allows organisations in the supply chain to forecast the time of arrival of a product.

For example, Toyota uses blockchain to follow thousands of its spare parts that are transported through many countries to maximise its automobile assembly process.

Customers could be easy to trace the products’ source anytime and anywhere as data in blockchain is completely transparent and updated immediately.

Blockchain has been applied in 26 sectors including agriculture, healthcare, transport and administrative management. — VNS
