Blockchain Technology Can Benefit Food and Agriculture
今年的重大事件之一是由“区块链技术” (BCT) 所支持的比特币等加密货币的崛起。现在我们简要地看看BCT及其对食品和农业的潜在效果和影响，特别是它如何能够具体影响到供应链，以及在农业粮食产业链中应用BCT需要什么。
One of this year’s big stories has been the rise of crypto-curriencies such as Bitcoin enabled by what is known as ‘blockchain technology’ (BCT). Here we would like to briefly look at BCT and its potential usefulness and implications for food and agriculture, especially how it can impact specific aspects of supply chains and what is needed to apply BCT in agri-food chains.
But first a word about BCT. BCT is not a single technology. BCT uses a combination of technologies that have a considerable history in computer science and in commercial applications. These component technologies include public/private key cryptography, cryptographic hash functions, database technologies especially distributed databases, consensus algorithms, and decentralised processing. The fundamental purpose is to achieve database consistency and integrity in a context of a distributed decentralised database.
BCT的关键技术选择包括：1) 是否需要权限才能访问区块链；2) 如何将新的区块加入区块链；3) 是否将区块链作为虚拟机，用于代表业务流程的程序运行；4) 是否使用加密货币。
Key technical choices of BCT include: 1) Whether permission is needed to access the blockchain; 2) Choice of how a new block is added to the blockchain; 3) Whether to use the blockchain as a virtual machine where programs representing business processes are run; 4) Whether or not to use cryptocurrency.
For BCT implementation, technical choices often result from the governance model chosen for the ecosystem of participants. So how can BCT be relevant to food and agriculture?
An increasing demand in society for greater information about food reflects the need for more transparency and the lack of trust. At the same time, more and more food products and beverages are branded and accompanied by a variety of certification schemes, which carry a risk of fraud (selling unqualified product with high-quality labels or claims) and adulteration.
In the current situation, much of the compliance data and information is audited by trusted third parties and stored either on paper or in a centralised database and these approaches are known to suffer from many informational problems such as the high cost and inefficiency of paper-based processes and fraud, corruption and error both on paper and in IT systems.
These information problems, indicating that current transparency and trust systems have not been able to solve or at times even have exacerbated the problems of low transparency and trust in agri-food chains, pose a severe threat to food safety, food quality, and sustainability. In particular, food integrity has become a major concern.
Food integrity refers to the fairness and authenticity of food in food value chains both at the physical layer and the digital layer, where the digital layer should provide reliable and trustworthy information on the origin and provenance of food products in the physical layer.
Blockchain technology provides a means to ensure permanence of records and potentially to facilitate the sharing of data between disparate actors in a food value chain. This potential may lead to an exciting paradigm shift facilitating transparency and trust in food chains that ensures food integrity.
Additionally, BCT can help consumers to observe whether farmers receive a fair share of the value created by the physical chain of activities that provide their foods from farm to fork.
In the coming year Dali SOL Farms will continue to strive and bring an expanded and diversified choice of nutritious and delicious products for consumers all over China.
