Food safety and blockchain

1. In July 2015, radar entered the virtual money market with a new attitude and quickly attracted many eyes. Looking back on the development of radar in recent months, it is full of twists and turns, and has been in the cycle of problems and solutions. No matter what difficulties we encounter, radar has not collapsed in front of people, and its strong vitality is determined by its value. Today's radars don't shine, but their value doesn't disappear
I believe many investors are full of confidence in whether the future value of radar can be reflected, because the power of science and technology is irresistible, and the height of radar's technological and theoretical innovation and practice is beyond the reach of any currency in the past. Radar explains a new concept of currency. Its emergence and rapid popularity is not accidental, nor is it just a game. In the real world, many countries have high inflation, and radar can protect users' wealth from inflation; Its transaction cost is almost zero, there is no control, anonymous, as a pure digital proct is very convenient to use; Because of its decentralization, it is difficult for the government to ban it. What is the value of radar in the future? As the use of radar becomes more and more popular, it will change many people's concept of money. In addition to the government, there is a new kind of credit that can be used to measure their own value. Just as the Internet has changed people's values and made them diversified, the greatest significance of the birth of radar is to innovate people's outlook on wealth. Radar will be a proct of improving the efficiency of asset flow around the world and recing costs. Its anonymity and independence from central control are symbols of freedom. It is also the place that fascinates users most. It is especially suitable for today. With the development of economy, people's respect for freedom is becoming increasingly strong. Of course, in the process of radar becoming a common currency, we need to strengthen supervision, establish rules, purify the radar market, and keep crime and money laundering away from radar. Only in this way can radar go further. So radar is a new expression of the concept of money in the Internet era
however, there is still a huge work to be done to ensure its future value. The first is to keep the radar usage up with the release speed. If it's just a distribution and there's no place to use it, then radar is also worthless, so the application and distribution should be synchronized. The technology development and related operating companies of radar should focus on making the transaction of radar an irresistible or inevitable new thing, making it a habit for the public to use radar, and creating conditions for the wide use of radar, just like we are now listening to iPods or shopping on Amazon. At that time, government and bank funds will be replaced by the Internet, which will give people more choices as the music and publishing instry experienced 15 years ago. Rome wasn't built in a day. It's a huge project, but it has great significance
when peripheral applications and transactions become an irreversible situation, radar will be considered successful and its value will have a foundation. Radar itself has a strong technical background and spiritual core. It is a combination of freedom spirit and creativity. There is still much room for such a creative combination. Let's wait and see!

2. Generally speaking, blockchain = block + chain. Block refers to the form of data, which is stored in the form of block (using higher-level encryption technology, which is difficult to tamper with). Chain is distributed storage technology. After block information is stored on the chain, distributed storage is carried out, which is linked with each other, and it is invalid to modify a single node

using blockchain technology, we can trace the source of food safety. This is an application scenario where blockchain technology is easy to implement and the technology is more mature. There are many procts that can be applied, including common commodities, high and low value-added procts
blockchain technology can improve mutual distrust, effectively improve proction relations, make it more transparent and digitally present traceability results
I'm going to develop the blockchain system. My friend introced Guangzhou Xuanling Network Technology Co., Ltd., which is a company engaged in software development and blockchain system development. Their development cases are not bad, involving a lot of business content, and the team strength is good. I feel the working atmosphere of this kind of company is comfortable, and I hope I can meet a good team.

3. By using blockchain, food companies can more quickly trace back to the source of food problems. This can not only help rece consumer risk, provide security, but also rece financial losses through targeted recall.

4. How to trace the origin of agricultural procts? In the past, agricultural proction paid special attention to & quot; Quantity security;, Agricultural science and technology also focus on increasing proction, resulting in excessive use or even abuse of pesticides and fertilizers, which will not only cause drug resies, but also bring secondary problems such as water and soil ecological environment pollution and drug resistance
with the change of food structure and consumption mode, the public has put forward higher requirements for the quality and safety of rice, so the establishment of rice blockchain traceability system is of great significance to both enterprises and consumers

for consumers, they can scan the anti-counterfeiting QR code on the rice package at any time by mobile phone. While querying the authenticity of the proct, consumers can obtain the information of rice from planting, processing, quality inspection, transportation to sales, and participate in the marketing means such as rewards, accumulated points and gifts issued by enterprises. Through traceability, consumers will be more assured and safer when they buy rice. In order to clarify the subject of responsibility and realize "the source can be traced, the destination can be traced, and the responsibility can be investigated"
for enterprises, rice is sown by many farmers, but it is unsalable because of various negative information in the market. At present, many enterprises have begun to use advertising to promote their brands and improve the trust of consumers. For some small-scale enterprises, there is not enough money to promote. At this time, we can use the blockchain Traceability Technology to enhance consumers' trust in the brand. Not only that, enterprises can also set up various rewards on the traceability platform to attract more consumers
therefore, it is necessary to establish a blockchain traceability system for rice enterprises and agricultural procts enterprises. Enterprises can use the well chain traceability platform to store multiple pictures to show the information of base proction, processing and circulation, and pesticide resie detection of agricultural procts in multiple dimensions. The whole process can be traced to create agricultural procts brand and realize root tracing.

5. In terms of food safety, with the help of blockchain technology, a reliable mechanism has been established for all transactions, which enables procers, suppliers, processors, distributors, retailers, regulatory agencies and consumers on the food chain to obtain the source and status information of food at any time, so as to track the contaminated food and speed up the removal of problem food, Effectively prevent the spread of food safety problems.

6. Thank you for the invitation. Last year, Hubei, Zhejiang and other places used the cold chain traceability system developed by ant chain for food safety, realizing "first stop code assignment, one code to the end, source can be traced, and destination can be traced". In this way, goods, warehouses, cars, and people can be traced accurately in the whole chain. This technology is really good, I sincerely hope to apply it to more instries
I hope the answer can help you!

7. The most basic problem of food safety is fidelity
