Blockchain technology: Advanced, modern

In the wave of industrial revolution 4.0, blockchain (block chain) is considered a “key” technology for digital transformation and building the future information technology platform.

With the ability to share real-time transparent data information, save storage space and high security, blockchain technology is one of the breakthrough technology trends, capable of wide application in many countries. professions and fields.

Blockchain is a technology that stores and transmits information using blocks that are linked together and expand over time. Each block contains information about the initialization time and is associated with previous blocks.

Blockchain is designed to resist data change. Information in the blockchain cannot be changed and can only be added when there is a consensus of all nodes in the system. Even if part of the blockchain system falls, other computers and nodes will continue to work to protect the information.

In particular, blockchain has the ability to transmit data without requiring intermediaries to confirm information. The blockchain system consists of many independent nodes capable of validating information.

In the field of agriculture or retail, blockchain will effectively serve for traceability to know where products and goods are imported and manufactured. For example, a livestock product from the farm to the consumer can have many stages. If blockchain technology is applied, it is possible to trace the breed origin, the history of the entire breeding process, information about the use of materials in the breeding process, information about the use of antibiotics, vaccines used to prevent diseases, on the use of product preservatives as well as information about the manufacturer and distributor related to the final product.

Approaching blockchain technology, the Institute of Food Safety and Nutrition has built a software for traceability of agricultural and food products (referred to as VFSC) that applies from planning and controlling the entire production process, circulation and consumption of agricultural products and foodstuffs, ensuring that at a certain time, once saved, people can read and see the images retrospectively, creating confidence in the producers and consumers of the products. agricultural products.

Applying high technology in agriculture

Currently, the requirements for traceability of agricultural products are very important, especially in export. Currently, blockchain technologies have appeared to serve traceability in livestock.

Currently, blockchain software is being applied in relatively large farms. From the access codes we can know which farm the seed is imported from, how much yield. Besides, it is possible to manage the breeding process such as animal feed for daily use, veterinary drugs, vaccines, etc.

Blockchain technology will also help farmers better manage the quality of agricultural products. Thereby serving the conditions of difficult export markets such as the United States, China or European countries.

VFSC software is built based on standards in accordance with international regulations, so it is possible to control the entire production process, from seed, materials to final product: at any time any certification organization identify what the certified organization is doing; All activities taking place on the farm are controlled.

The technology applied by VFSC is blockchain, the data is not modified, not deleted, etc., ensuring the reliability through which information can be transparent throughout the process from production to goods in the hands of consumers. how many days, what kind of materials are used, what varieties… how to harvest, preserve, people will believe.

The traceability stamp must indicate from the seed, manure, medicine, etc. to the product over how many days, what is the use of the materials used; Tracing to the root when sowing, which day to fertilize, which day to spray … that is electronic retrieval.

Recognizing the importance of applying high technology in agriculture, the National Center for Agricultural Extension (MARD) organized a training session on blockchain software for Hanoi farmers.

According to Ms. Ha Thuy Hanh, Deputy Director of the National Center for Agricultural Extension: “Currently, VFSC has been applied to 5 groups of agricultural products: cultivation, husbandry, aquatic products, ornamental plants and medicinal herbs. and in 26 provinces and cities across the country.”

After being trained in blockchain software, Ms. Le Thi Thu Hien, technical officer of Agricultural Extension Station in Son Tay town, Hanoi, said that the management of livestock supplies is much simpler.

“During the breeding process, disease prevention and treatment can be entered into the system for later export and sale, we have traceability from the very beginning to check whether this agricultural product is safe or not. “, said Mrs. Hien.
