⑴ What benefits does the application of blockchain technology bring to enterprises?

Blockchain classification:

1 Private chain

< p> refers to a blockchain with certain centralized control. Just using the general ledger technology of the blockchain for accounting, it can be a company or an individual, with exclusive write permission to the blockchain. This chain is not much different from other distributed storage solutions. The only participating nodes are the users themselves, and data access and use are subject to strict permission management. Since the alliance chain has certain centralized control, it can also be considered to belong to the category of private chain.

Features: Since the user has the final say, the data inside has no characteristics that cannot be changed, and there is not much protection for third parties. Generally used for internal audit. The vice president of technology at Huobi Network believes that private chains do have a large number of scenarios that can meet the needs of the real world. Limited decentralization makes it easier to reach consensus, can make transactions faster and more efficient, and can provide more controlled function. Decentralization is the core value of blockchain technology. If the private chain cannot fully utilize the decentralized trust foundation constructed by the public chain in practice, its development space will be limited.

2 Public Chain

Public blockchain is the earliest blockchain and the most widely used blockchain at present. It refers to a blockchain like the Bitcoin blockchain that is completely decentralized and not controlled by any institution. Any individual or group in the world can send a transaction, and the transaction can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Participants in the consensus process maintain the security of the database through cryptography and built-in economic incentives.

Features: Completely open, uncontrolled, relying on encryption technology to ensure security.

3 Alliance Chain

A certain group designates multiple pre-selected nodes as bookkeepers. The generation of each block is jointly decided by all pre-selected nodes. Other access nodes You can participate in transactions, but you are not involved in the accounting process (it is essentially still managed accounting, but it becomes distributed accounting. How many pre-selected nodes and how to decide the accountant of each block becomes the main risk point of the blockchain) , anyone else can make limited queries through the blockchain’s open API.

The nodes participating in the blockchain are selected in advance, and there are likely to be good network connections between the nodes. Other consensus algorithms other than proof of work can be used on such a blockchain. For example, a certain blockchain has been established among 100 financial institutions, and it is stipulated that more than 67 institutions must agree to reach a consensus.

Prospects:

The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted new developments in various industries. This kind of The impact of the driving force on society and the promotion of economic activities are also huge. Many new industry phenomena will occur one after another, and the public is also waiting and watching, hoping that this brand-new technology will be used by various industries to create betterBenefit all industries.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus reserve mechanism is a mathematical algorithm in the blockchain system to establish trust and obtain rights and interests between different nodes.

⑵ Does blockchain need to be adopted by all companies in the supply chain?

Blockchain needs to be adopted by all companies in the supply chain. According to relevant public information, blockchain and supply chain are inseparable. Blockchain can play a role in the planning, procurement, manufacturing, delivery, and recycling of the supply chain. Therefore, blockchain needs to be adopted by all companies in the supply chain. of.

⑶ What are the blockchain companies?

As follows:

At present, almost all Internet companies have started to develop blockchain. Most traditional financial companies are involved. There are serious pure blockchain companies that do some technology research and development, including Yunxiang, Qulian, and Taiyi; there are also companies that do public chain main chains, such as Xunlei, Xiaoyi, Byuan, etc.

There are also many companies that are actually working on blockchain technology, such as Qulian Technology, Wanxiang Blockchain, Energy Chain Group, Complex Beauty Technology, Galaxy Blockchain, Zhigui Technology, and Medical Chain The groups are all well-known companies in the industry with good technology. Internet giants basically have blockchain sections.

More than 10,000 new blockchain companies will be added in 2020

Despite the COVID-19 pandemic, China’s blockchain industry is still growing significantly. As of July 2020, more than 10,000 new blockchain companies have been established in China. The number of new companies in 2020 exceeded the 18,500 in 2019.

The continuous influx of new blockchain companies has laid the foundation for the development of my country's blockchain industry. However, due to the rapid development of the blockchain industry, there is a shortage of professional talents to match it, and most employers will face the problem of recruiting people.

⑷ What companies are currently using blockchain technology?

Large-scale domestic blockchain companies include Xinchen Technology, Yinjiang Shares, Cultural Great Wall, Radio and Television Express, Hengsheng Electronics, etc. .

1. Xinchen Technology

The company's current main business is application software development business, software and hardware system integration business and professional technical service business. In recent years, Xinchen Technology has been more bold in its attempts at innovation. The company has made certain progress in the application of new technologies such as cloud computing, big data, artificial intelligence, and blockchain in the financial industry. The domestic letter of credit business system based on blockchain technology has been successfully launched in banks and is expected to gradually become a new growth point for the company's software solutions business.

2. Yinjiang Co., Ltd.

The company mainly provides intelligent system engineering and services to users in transportation, medical, construction and other industries. "Elite" has conducted multiple follow-up reports on Yinjiang Shares. This company has made in-depth development in smart cities in recent years, covering all aspects of urban residents' lives including transportation, medical care, construction, environment, energy, education, and finance.

The company is a key software enterprise within the national planning layout, a key high-tech enterprise in the National Torch Plan, one of the top 100 enterprises in China's software business revenue, one of the top 100 high-tech enterprises in Zhejiang Province, and one of the most promising small and medium-sized enterprises in China in 2010 by Forbes. One of the top 100 enterprises and a unit with outstanding contributions to China's informatization construction over the past 30 years of reform and opening up. It is one of the companies with the highest comprehensive business qualifications and the most comprehensive types in the domestic industry.

3. Cultural Great Wall

Cultural Great Wall began to acquire large educational institutions such as Lianxun Education, Zhiyou Zhenlong, and Jade Sect World Education in 2015, and has become a leader in the A-share education industry. For listed companies, the rapid growth of the education industry has become a new driving force for the company's performance growth. Its subsidiaries began to lay out the blockchain industry in 2017, investing in the research and development of blockchain-related technologies, and obtained four blockchain technology copyrights in March 2018, becoming a pioneer in blockchain applications in the field of education. .

4. Radio and Television Express

The company stated on the investor interaction platform that it has been paying attention to the development trend of digital currency for a long time. Focusing on the industry development needs of digital currency, the company has set up a dedicated team to carry out Related work, including research on blockchain technology.

5. Hundsun Electronics

On June 1, 2016, the Financial Blockchain Cooperation Alliance was established in Shenzhen. Hundsun Electronics is one of the 25 initiators to use the blockchain Chain technology implements a digital ticket system based on the alliance chain.

⑸ What are the applications of blockchain in the industry?

Taking the tourism industry as an example, blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, credit consumption management, Tracking pilots' professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumer points management are several application areas. In addition, with the development of blockchain, many related top domain names have been registered, which has had a relatively large impact on the domain name industry. In addition, blockchain also has applications in finance, games, entertainment and other fields.

⑹ What convenience can the blockchain service platform launched by JD.com bring to the operation of enterprises?

The concept of blockchain has become very popular in recent years, but in addition to digital currency (virtual currency) Except for currency), there have not been many implementation projects in other fields. JD.com’s recently released “Zhi Zhen Chain” can be said to be an important attempt to implement blockchain in business scenarios. After all, JD.com itself is already very large and has established a relatively complete ecosystem. If “Zhi Zhen Chain” If it can gradually be implemented and play a role within the JD system, it will have a lot of reference value for blockchain applications in the commercial field.

The blockchain itself has the characteristics of tamper-proof, traceability, full process, decentralization, etc., and these characteristics are more consistent with the e-commerce field where market operation is relatively clear. In my opinion, the blockchain platform created by JD.com can bring the following benefits:

First, products can be traced. Product anti-counterfeiting has always been a headache for e-commerce platforms.This problem also occupies a large part of the e-commerce platform’s expenses. After using blockchain technology, product tracking can be completed to ensure product traceability. Product authenticity will no longer be a problem that troubles merchants.

Second, the service is traceable. Not only products can be traced, but services can also be traced using blockchain technology. Services that follow products are often one of the core factors that affect user experience. Making services traceable can build a service system to facilitate smoother connection and cooperation between merchants and between merchants and users.

Third, standardize bill (contract) management. Invoice management has always been a troublesome matter in a business environment. After using blockchain, standardized management of invoices can be completed. Blockchain notes have natural characteristics such as being unforgeable, tamperable, traceable, and verifiable, and these characteristics can avoid a large number of transaction risks.

Fourth, the process is intelligent and standardized. By using the "Smart Chain", many companies participating in the JD platform can effectively use the "Smart Chain" to complete various business operations (to be developed and improved), which greatly lowers the entry threshold for participating companies.

I believe that the "Smart Chain" will be further developed and improved in the future, and will also bring more convenience and benefits to service merchants.

My research direction is big data and artificial intelligence. I am currently leading graduate students in related fields. I will continue to write some popular science articles on big data on Toutiao. Friends who are interested can check it out. If you pay attention to me, I believe you will gain something from the demolition tribe.

If you have any questions about big data, you can also consult me.

Thank you!

⑺ Why should enterprises use blockchain

In many cases of blockchain commercial applications, we can always see the word BaaS, and BaaS is Blockchain
as
a
The abbreviation of Service, translated into Chinese as "Blockchain as a Service". So what exactly is Blockchain as a Service BaaS? With this question in mind, we followed Xiao Wang from the Renren Blockchain Technology Team to discuss it in detail.
According to Xiao Wang: Blockchain as a Service BaaS is a concept mainly proposed by the two giants Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service that combines blockchain technology. . For example, Microsoft's Azure cloud computing platform and IBM's Bluemix
Garage cloud platform both provide blockchain as a service BaaS.
Blockchain as a Service BaaS is a space created by companies such as Microsoft and IBM from their own cloud service networks to run a certain blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of BaaS nodes is to quickly establish the development environment you need and provide a series of operational services such as blockchain-based search queries, transaction submissions, and data analysis. These services can both It is centralized or decentralized, and is used to help developers verify their concepts and models faster. BaThe serviceability of aS nodes is reflected in: stronger tools, making it easier to create, deploy, run and monitor blockchains.

⑻ What is blockchain and what is its practical significance for enterprises
