The application of blockchain technology to food industry
what is centralization
the so-called centralization means "ownership" or ownership by the company. For example, Tencent's q-coin, which is issued by Tencent, is a kind of centralized electronic currency, including the total amount and the issuing method, is supervised and controlled by Tencent. You can use it, trade and go shopping, but you always have to operate in the framework of Tencent, and the final right of interpretation belongs to Tencent
the issuing mode of bitcoin is preset by the program and encryption algorithm, and runs on multiple nodes all over the world. No one or organization can modify it (everyone has his own account book, so it is impossible for one person to control everyone's account book at the same time. If there is such a technology, why should it be so complicated, If you want to blackmail money into your account, you will be the richest man in the world. There is no one left, And it is not controlled by any single person or organization
take an example: for example, Lao Zhang borrows 100 yuan from Lao Li, but Lao Li is afraid that he will default, so he asks the village head to do notarization and write down the account. This is called centralization. But if you don't find the village head, you can use the loudspeaker to shout in the village: "I Lao Li lent Lao Zhang 100 yuan! Please put it in the account book. "We all put this account in our own account book. This is called decentralization
anyone who transfers money between them will release information through loudspeakers. After receiving the information, everyone will record the transaction in their own account book. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma, Lao Wang and other families have ledgers
the main advantages of blockchain are that it does not need intermediary participation, the whole process is open and transparent, and the cost is low, and the data security is high
at present, blockchain is in a stage where everyone talks about blockchain, but can't perceive its actual technical charm. Since 2017, it has graally come into our sight, and we have graally realized that bitcoin is more fierce than real estate speculation (the price of mining machinery has skyrocketed! The news is on the screen But I still don't know
so, in which fields can blockchain be applied, what kind of changes will it bring to our future life
the core key: everyone has an account book, everyone has an account book, and the information recorded in each person's account book is consistent and synchronous, and the information is completely transparent. If it is fake, it will be the public enemy of the whole people, which greatly increases the cost of data fraud
core key 2: decentralization, which does not need a central system to manage data, prevents some people from changing data and damages the interests of the majority of people
Application:
1. Account security and privacy protection: currency transfer, exchange, payment system. Blockchain can help prevent data manipulation and fraud, prevent distributed denial of service attacks (DDoS), and effectively protect users' network privacy. Key words: anti counterfeiting, anti-counterfeiting, loan payment
2. Copyright regulation and interest disputes: for example, when a song is downloaded, from the author to the procer and then to the singer, they can get payment in real time through the blockchain, without having to wait for a long time like the traditional way, or even get no reward e to right disputes. Instead of waiting for publishers to provide royalty checks, creators can freely control the process from publishing to payment through blockchain application. Key words: real time receipt, no property dispute
3. Internet of things + artificial intelligence: the intelligent devices in the Internet of things based on the blockchain will be used to monitor the real-time situation of urban infrastructure such as bridges, roads, power grids, etc. the blockchain can connect these intelligent devices together for unified management to help them monitor more efficiently. This will help people better understand how to build a smart city in the future. Key words: unified monitoring, intelligent city
4: proof of existence: in life, once you are asked to prove that you are you, that your mother is your mother, that you have never been married, that the house belongs to you, and so on, things seem very simple. Once it falls on you, it is a great trouble. The application of blockchain technology can perfectly solve the above embarrassment. At that time, all the information that belongs to you will be recorded accurately and can not be tampered with. No one has the right to change it. When the technology develops to a certain stage, birth certificate and marriage certificate may be recorded on the blockchain. Keywords: no keywords
in addition to the application scenarios mentioned above, blockchain technology can also be applied to e-commerce, data storage, logistics and other fields. As long as we grasp the characteristics of blockchain technology, it will become easy to understand.
(1) The underlying platform of the blockchain is a domestic independent and controllable blockchain platform developed by the science and technology of the blockchain. With the characteristics of high performance, high availability, scalability, easy operation and maintenance, strong privacy protection, and hybrid storage, the platform cooperates with the data sharing and security computing platform bitxmesh, the blockchain open service platform filoop, the supply chain finance platform filolink, and other platforms The deposit service platform filoink and the smart contract security R & D platform meshsec can better support the applications of enterprises, governments, instry alliances and other instries, and promote the efficient circulation of value among multiple institutions
(2) JD chain is the underlying framework of enterprise level blockchain independently developed by JD, and its birth marks that JD has started the construction of "Zhizhen ecology" based on the baas platform of blockchain and the underlying chain of "jdchain". Relying on the "one key deployment" capability of multiple optimization implementation, JD Zhizhen chain service platform has achieved the leading second level blockchain node deployment. In addition, it also has the core advantages of open compatibility with a variety of underlying, enterprise level dynamic networking and other mature applications. The timely launch of JD Zhizhen chain will effectively promote the large-scale implementation of enterprise level blockchain applications in various instries, and promote the construction of China's and global trust economy
(3) thunderchain is a blockchain application project independently researched and developed by netxin technology under thunderchain, which has high concurrency and second level confirmation capability of millions of TPS. Based on the research and development of high-performance blockchain procts, Xunlei has built an open platform of Xunlei chain, which helps enterprises or indivial developers to deploy smart contracts, easily realize the proct and service on the chain, and make the application development of blockchain more convenient
(4) Jingtong blockchain
Jingtong blockchain is the core underlying technology of Jingtong technology's blockchain with independent intellectual property rights. It is an effective decentralized Internet trading network based on blockchain technology, which adopts layered design (5 layers) underlying platform and multi language intelligent contract system, and has realized cross chain function. It has multi-level, all-round and one-stop service capabilities such as private chain, cloud chain and alliance chain. The layout of instry and regional ecology has taken shape
in addition to the above blockchain procts, there are community led LTC, cosmos, iota, Neuros, nuls, MOAC, etc., and enterprise led ripple, stellar, Weizhong bcos, network xuperchain, Huawei, Ping'an, Wanxiang, ant financial services, Zhongan, Bubi, matrix element, secret ape, zhongxiangbit, complex beauty, Shanghai Lianjing, etc
extended data:
blockchain is far more than a technology, which involves the spirit of "multi-party cooperation". In modern society, a lot of things must rely on everyone's cooperation to achieve 1 + 1 & gt; But we should try our best to avoid the problem of "information asymmetry" in cooperation
therefore, members of the alliance should keep accounts and share data together, and make everything public to eliminate "information asymmetry", so as to protect everyone's interests and make the business environment develop healthily. Honest work will get e benefits, if cheating will naturally be known to all. Technology is the foundation to help achieve this pattern. This is the more important "blockchain thinking"
food safety problem has always been the biggest pain. Due to the large variety and quantity of food materials required by the catering instry every day, it will take a lot of time and capital costs to use the traditional method for food traceability, which greatly increases the cost of people to eat safe food
with the development of blockchain technology, the regional centralized system of blockchain technology can create a database for each kind of food material, which will record the storage conditions, delivery time, origin and other information of each food material, which can speed up the acquisition and flow of information, greatly rece the cost of food traceability, and enable people to eat better food with less money.
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!
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.
I hope the answer can help you!
