『一』 Is blockchain safe?

When it comes to the essence of blockchain, I believe several keywords are already familiar. For example, decentralization, trustlessness, consensus mechanism, asymmetric encryption, distributed accounting, immutability, absolute transparency, openness, etc. At the same time, some teaching posts also list the structure of the blockchain, such as data layer, network layer, consensus layer, incentive layer, contract layer, and application layer.
However, anyone with a discerning eye can tell at a glance, why is there no security layer? In fact, several key features of blockchain have already solved security issues. First, blockchain uses asymmetric encryption technology. In fact, encryption and decryption are different keys, namely the public key and the private key. To put it simply, the public key is made public, while the private key is absolutely confidential.
Secondly, distributed accounting is the way blockchain stores data. It can also be understood as distributed storage, which is consistent with the concept of decentralization. From the perspective of the form of the ledger, it means that there is no central ledger in the network, and the ledger is stored in each node. Each node can work independently or act as a central node. Therefore, there will be no situation where the central node is attacked, resulting in the loss of core ledgers or data, and the entire network being paralyzed.
Furthermore, non-tamperability is a basic feature of the blockchain. As long as it is on the chain, it cannot be modified, and it cannot be deleted. If changes are needed, based on the principles of transparency and openness, the entire network and all nodes need to be notified. Therefore, under a democratic mechanism, the possibility of arbitrarily tampering with data is very low. Therefore, blockchain technology is applied in various industries, such as finance, payment, traceability, games, etc., such as the online "Universe", Tencent's "Let's Catch Monsters", and Zhongan Huanyu Blockchain's "DR Dragon Hunt" are examples of this area. Safe and high-quality products under blockchain technology.

『二』Brief description of the role of blockchain technology in the development of modern agriculture

Brief description of the role of blockchain technology in the development of modern agriculture in making agricultural products traceable , crops have insurance, which directly promotes the docking of production and sales, makes agricultural transactions more convenient, and makes agricultural finance more efficient. Zaipidian

1. Make agricultural products traceable: The most common use of blockchain in food and agricultural supply chains is to improve traceability. It enables companies to quickly trace unsafe produce to its source and where it was distributed. This prevents disease, saves lives and reduces the cost of product recalls.

『三』 I almost forgot to ask what you should pay attention to when managing money on the blockchain

Every investment product needs to be risk assessed, including the risk assessment of the project. Background, team, technology and market situation.

Security: Financial management products on the blockchain also need to consider their security, including whether there is a risk of hacker attacks and whether there are sufficient security measures to protect investors' assets.

『四』What are the blockchain applications in the agricultural field

Blockchain decentralization It will significantly reduce Internet maintenance costs and improve the intelligence and scale of the agricultural Internet of Things. At the same time, the agricultural product traceability system based on blockchain technology solves consumers' trust crisis in products and makes people's dining tables healthier and safer.
In the agricultural field, what trends and directions will blockchain agriculture present?
1. Internet of Things + Drones + Blockchain
Logistics ensures the interconnection of all things, drones provide production management services, and blockchain provides recording and traceability technologies. It will be conducive to the development of precision agriculture, reduce pesticide input, and improve the quality of agricultural products.
2. Blockchain + Data + Artificial Intelligence
Blockchain applied to agriculture can eliminate information asymmetry to the greatest extent, improve information transparency and timely response capabilities of the entire industry chain, thereby realizing the realization of the entire industry value added.
The integrated development of blockchain + data + artificial intelligence can maximize the value of agricultural big data and reduce input costs.
3. Blockchain + Agricultural Finance
In early February, the Chinese government issued the “Guiding Opinions on the Revitalization of Rural Financial Services.” The new framework proposed this time is part of the plan to improve the efficiency of financial services in the national rural revitalization plan.
Blockchain + agricultural finance will provide convenient access to loans to small farmers and bring authenticity and predictability to the credit reporting of agricultural financial institutions.
4. Blockchain + Rural Logistics
Due to the fragmentation of rural logistics, parcels are lost and agricultural products are difficult to transport. But blockchain technology can solve these problems.
5. Blockchain + Agricultural Supply Chain
This type of application is the reason why major shopping malls are grafting blockchain. For example: Walmart, Carrefour and other large supermarkets have incorporated the entire fresh food and food supply chain into blockchain management, thereby reducing costs and improving product quality.safety. At present, American agricultural giants such as Cargill are vigorously developing the application of blockchain + agricultural supply chain finance.
In addition to agriculture, the application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. The popularity of blockchain and Bitcoin has led to many related top All domain names have been registered, which has had a relatively large impact on the domain name industry.

『Wu』Is blockchain safe?

Hi, everyone, I am your Q&A assistant - Zi Xiaochen. Recently, blockchain resistance has been widely concerned and discussed. But there are many people who don’t know much about its safety. So today we will talk about the security issues of blockchain.
First of all, would you like to hear an easy-to-understand metaphor? A friend of mine joked: "Blockchain is like a password lock. Without a password, no one can open it." Although this is simple and interesting, it makes a lot of sense. Since the blockchain uses distributed ledger technology, data is stored in a huge network, and the transmission between each node uses asymmetric encryption, the blockchain has extremely high security, and third-party attacks are very vulnerable. difficult.
Secondly, of course there are some security issues that need attention. For example, hacker attack methods such as "51% attack" can pose a threat to the blockchain. In addition, there are also security risks in virtual currency trading venues, such as Bitcoin exchanges, and you need to pay attention to precautions. Therefore, when choosing a blockchain platform or participating in virtual currency transactions, you need to know more and consider carefully to avoid losses.
In short, blockchain is an open technology, which has huge advantages in ensuring data security and preventing tampering. But we also need to be alert to potential security risks and choose reliable platforms and exchanges to participate in cryptocurrency investments.
I hope my answer can help you better understand the blockchain and its security issues. If you have any questions or want to share your experience, please feel free to message me privately! Finally, don’t forget to like, comment and forward, follow my articles, more content is waiting for you!

『Lu』What are the main data security measures of the supply chain blockchain?

The main data security measures include identity authentication, access control, data encryption, data backup, etc.

『撒』 Can blockchain agriculture really ensure food safety?

How to trace the origin of agricultural products? Let’s take a look at the traceability of rice + blockchain
In the past, agricultural production paid special attention to "quantity security", and agricultural science and technology also focused on increasing production, resulting in the overuse and even abuse of pesticides and fertilizers, which not only caused The problem of drug residues will also bring about secondary problems such as water and soil ecological environment pollution and drug resistance.
With the changes in dietary structure and consumption patterns, the public has put forward higher requirements for the quality and safety of rice. Therefore, establishing a blockchain traceability system for rice is of great significance to both enterprises and consumers.

For consumers, they can scan the anti-counterfeiting QR code on the rice packaging at any time with their mobile phones. While checking the authenticity of the product, consumers can obtain information on rice from planting, processing, quality inspection, transportation to sales, etc. Participate in marketing methods such as rewards, accumulated points, gifts, etc. issued by participating companies. Through traceability, consumers will be more assured and safer when buying rice. In order to clarify the subject of responsibility, "the source can be checked, the destination can be traced, and the responsibility can be held accountable."
For companies, rice is sown by many farmers with hard work, but due to various negative information currently on the market, rice is unsaleable. At present, many companies have begun to use advertising to promote their brands and improve consumer trust. For some small-scale enterprises that do not have enough funds to promote, blockchain traceability technology can be used to enhance consumers' trust in the brand. Not only that, companies can also set up various rewards on the traceability platform to attract more consumers.
Therefore, for rice companies and agricultural products companies, it is essential to establish a blockchain traceability system. Enterprises can use the well chain traceability platform to store multiple frames of pictures to display information on base production, processing and circulation, and pesticide residue testing of agricultural products in multiple dimensions. The entire process can be traced, creating a brand for agricultural products and achieving traceability.

『8』 What is the main way to ensure the security of blockchain?

Blockchain technology is a distributed recording technology that encrypts and distributes storage of data. to ensure data security and reliability.
The security of the blockchain is mainly ensured through the following methods:
1. Encryption technology: The blockchain uses symmetric encryption and asymmetric encryption algorithms, which can effectively protect the security of data.
2. Distributed storage: Blockchain data is not stored centrally on a single node, but is stored dispersedly on various nodes in the network, which effectively prevents data tampering and loss.
3. Consensus mechanism: Blockchain usually uses a consensus mechanism to confirm the legitimacy of transactions, which helps prevent malicious transactions from occurring.
4. Contract mechanism: Blockchain can automatically execute transactions through smart contracts, which helps prevent manipulation of transactions.
Blockchain technology also brings some challenges while achieving security. For example, the security of the blockchain can be attacked by vulnerabilities, or assets can be stolen because private keys are leaked. Therefore, when using blockchain technology, you also need to pay attention to issues such as identity authentication and password security to ensure the security of the blockchain.
In addition, the security of blockchain technology may also be affected by policies, regulations, etc. For example, in some countries and regions, blockchain technology may be subject to censorship and restrictions, which may also have an impact on the security of the blockchain.
In general, the security of blockchain technology is mainly guaranteed through encryption technology, distributed storage, consensus mechanism and contract mechanism, but other challenges and influencing factors need to be paid attention to.

『九』 What is the value of blockchain agriculture? What opportunities and development can blockchain bring to agriculture?

The value of blockchain lies in security. The value of blockchain agriculture is for food safety, and These data play a very important reference role in the reproduction of agricultural products.
With the development of value-oriented agriculture, precision agriculture and centralized agricultural systems, this blockchain technology will promote the continuous development of the agricultural industry, and its technology can also bring more jobs.
Blockchain agriculture has already existed, but some areas are not mature enough, especially the traceability aspect. However, the launch of a Dmtc agricultural traceability project this year has filled this gap.
In terms of data collection, through the use of artificial intelligence and Internet of Things technology, it runs through the entire agricultural ecological chain. During agricultural production, the production environment data and production process data of agricultural products are fully automatically recorded. When agricultural products are transported, they are fully automatically recorded. For transportation data, DMTC terminals are connected to smart micromarkets during sales to collect consumption behavior data of product consumers. Through the popularization of smart micromarkets, terminals are spread throughout living quarters, collecting rich data for industrial development and progress, and more fully carrying the value of the agricultural ecological chain. Transmission and information transmission

『Shi』How does blockchain protect food safety

In layman’s terms, blockchain = block + chain, and block refers to the form of data. It is stored in the form of blocks (using higher-level encryption technology and difficult to tamper with). The chain is a distributed storage technology. After the block information is stored on the chain, it is distributed and stored, interlocking, and individual nodes are modified. invalid.

Using blockchain technology, food safety traceability can be carried out. This is an application scenario where blockchain technology is easier to implement and the technology is more mature. There are also many products that can be applied, including various common Commodities, high and low value-added products.
Blockchain technology can improve the situation of mutual distrust, effectively improve production relations, make it more transparent, and present traceability results digitally.
I am planning to develop a blockchain system. A friend introduced me to Guangzhou Xuanling Network Technology Co., Ltd. This is a company that specializes in software development and blockchain system development. Their development cases are pretty good and the business content involved Quite a few, the team is pretty good. I feel that the working atmosphere of this type of company is comfortable, and I hope that I can also meet a good team.
