Ⅰ A brief analysis of the application of blockchain technology

A brief analysis of the application of blockchain technology
For the recently popular blockchain technology, I believe many people Don't know its applicable scenarios. Although theoretically any industry related to digital networks can be applied, from the perspective of implementation costs, the following industries are more suitable for blockchain technology.
Since the essence of the blockchain is a distributed accounting ledger, digital currencies represented by Bitcoin and Ethereum are also a very simple and safe settlement method. The most important thing in the financial field is the accounting and clearing process. Blockchain technology can greatly improve the efficiency of traditional banks and the financial industry.
However, all of the above are the basic functions of blockchain, and there is still a lot of room for improvement. Currently, there is no mature blockchain financial project in the world. We still have a long way to go. Way to go.

When it comes to the application of blockchain, the first thing we think of is the banking and financial industries. Since the essence of blockchain is a distributed accounting system, it is most suitable for the financial industry. Digital currency based on blockchain can also be used in transactions, clearing and settlement, etc. The security and decentralization of blockchain are used to ensure the security of accounting. Currently, major countries are exploring this application.
In addition, many businesses of government agencies are also very suitable for the application of blockchain technology, such as the management of resident identity information, ownership records, product supervision, etc. Ensure the security and privacy of critical information through distributed immutable records. Many countries such as Ireland have included this development plan as a short-term goal, and it is also one of the more common areas of use of blockchain.
Financial field: The financial field is the field where blockchain has the most applications besides Bitcoin. After all, financial development also involves currency and digital currency. Especially in the past two years, the development of digital currencies has also driven the application of blockchain.
Regarding blockchain deception, when blockchain first emerged, it was questioned by many people and was called blockchain deception. Now the chief economists of various countries in the region have begun to quit studying blockchain, proving that blockchain is gradually being accepted by the public.
In addition, due to the emergence of Ethereum smart contracts, blockchain can also better assist resource sharing related industries, such as our common shared bicycles and other products. Another example is the medical field. We can also use blockchain technology to improve efficiency and safety, which will bring about a qualitative change in this industry.
I believe everyone has a preliminary understanding of the practical application of blockchain. Looking back at the ICO craze in China some time ago, a large number of unreliable projects such as dog chains forced speculation on the concept. Obviously, domestic investors There is not enough understanding of the blockchain application field, so stopping ICO not only regulates the industry, but also protects the investing public.

II What are the technological innovations and applications of blockchain

1. Blockchain system

As the underlying technology of Bitcoin, the blockchain system generally consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

1. Data layer

The data layer encapsulates basic data and basic algorithms such as underlying data blocks and related data encryption and timestamps. It mainly describes the physics of the blockchain. The form is the chain structure on the blockchain starting from the genesis block. It includes the block data and chain structure of the blockchain, as well as the random numbers, timestamps, public and private key data on the blocks, etc. It is the underlying data structure in the entire blockchain technology.

2. Network layer

The network layer mainly implements distributed network mechanisms through P2P technology, including P2P networking mechanisms, data dissemination mechanisms and data verification mechanisms. Therefore, in essence, the blockchain is a P2P network with an automatic networking mechanism, and nodes maintain communication by maintaining a common blockchain structure.

3. Consensus layer

The consensus layer includes consensus algorithms and consensus mechanisms. The consensus layer allows highly dispersed nodes to efficiently reach consensus on the validity of block data in a decentralized blockchain network. It is one of the core technologies of the blockchain and is also the governance mechanism of the blockchain community. There are currently dozens of consensus mechanism algorithms, including proof of work, proof of equity, proof of equity authorization, proof of burning, proof of importance, etc.

4. Incentive layer

The incentive layer mainly includes the issuance system and distribution system of economic incentives. Its function is to provide certain incentives to encourage nodes to participate in the security of the blockchain. Verification work, and incorporating economic factors into the blockchain technology system, incentivizing nodes that abide by the rules to participate in accounting, and punishing nodes that do not abide by the rules.

5. Contract layer

The contract layer mainly includes scripts, codes, algorithm mechanisms and smart contracts, and is the basis for blockchain programmability. It embeds code into the blockchain or token, and can implement customized smart contracts. When certain constraints are reached, it can be automatically executed without going through a third party, which is the basis for trustless blockchains.

6. Application layer

The application layer encapsulates various application scenarios and cases, similar to applications on computer operating systems, portals on Internet browsers, search Engine, e-mall or APP on mobile phone. It deploys blockchain technology applications on Ethereum, EOS, QTUM, etc., and implements them in real life scenarios. In the future, programmable finance and programmable society will be built on the application layer.

The data layer, network layer, and consensus layer are necessary elements to build blockchain technology. Without any layer, it cannot be called blockchain technology in the true sense; incentive layer, contract layer and application layer are not necessary factors for every blockchain application, and some blockchain applications do not completely include this three-layer structure.

From a business perspective, blockchain technology has its own characteristics, that is, it is sufficiently digital, it is cross-border, cross-time and space, and cross-organization. The flow of data has no boundaries, so the blockchain is distributed at the same time, it is self-organized and decentralized.

So the origin of blockchain and the application of any new disruptive technology have always had two routes, or two methods. One way is to regard it as a tool and use it to improve the traditional business model and obtain an improvement in marginal benefits. The other is to treat it as a system to reconstruct the underlying logic of business.

There is a good example of these two application methods in the past few years. When Internet companies are promoting "Internet+", we also see many traditional business organizations saying that it is not "Internet+", but "+Internet". So where are those people who shout "+Internet" now? Some people think that the Internet is just a technology used to improve it. Some Internet technologies can be added to traditional things. For example, if you use the Internet as email, you build an email system and think it is the Internet. But some people treat the Internet as a system and reconstruct the business from the bottom up. In the end, you will find that you are unemployed.

The second is decentralization. Why go to the center? Regional center technology in business has brought about business decentralization, which is an inevitable trend in history. Where is this trend? I think there are two points. One is economic globalization and entering version 2.0. Now through the Internet, it is no longer the company that is globalizing, nor the company turning itself into a multinational company, but the Internet is empowering any individual, so that it can sell its products through the Internet in a small county in China. worldwide. When economic globalization develops to personal globalization, solving point-to-point transactions and point-to-point services becomes a prominent issue. Then the real-time clearing and settlement and point-to-point transaction settlement brought by blockchain technology can just help the globalization of personal business activities.

The third is the digitalization of the economy. When data is collected to a certain extent, its circulation is basically across time and space. The demand for financial payments from commercial activities is carried with them anytime and anywhere, but it is impossible to provide scenario-based and virtualized payment settlement anytime, anywhere and on demand. Services will eventually be eliminated by technology and the market.

Ⅲ How does blockchain technology empower the real industry

Now there are domestic companies that have implemented blockchain technology into actual industries. For example, Wanglian Technology has applied blockchain to financial services, medical health, IP copyright, Internet of Things, sharing economy, communications, education,
Social management, charity, culture and entertainment and other fields

IV My understanding of blockchain technology

Blockchain is not a scourge

With the development of blockchain With the development of technology, especially the application of cross-public chain technology, the space for blockchain development and application is becoming more and more extensive. Let’s briefly introduce blockchain.

Blockchain is an important concept of Bitcoin. It uses a blockchain data structure to verify and store data; it uses a distributed node consensus algorithm to generate and update data; it uses cryptography. , ensuring the security of data transmission and access; using smart contracts composed of automated script codes to program and operate data as a new distributed infrastructure and computing method.

It is essentially a disintermediated database. As the underlying technology of Bitcoin, it also has new application models of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. .

Through this application model, blockchain technology can achieve the following three functions: First, ensure that the data on the chain cannot be tampered with or forged, and improve the credibility and credibility of the data; Second, realize the traceability of transactions, achieve traceability supervision and responsibility tracking; third, smart contracts can be automatically executed based on the contract, thereby improving work efficiency and reducing operating costs.

Blockchain technology is now being applied in Alipay to improve security and increase credibility and fairness. I believe that as the times progress, there will be more and more applications of blockchain and it will increasingly enter the lives of ordinary people.

Conclusion: Blockchain and digital currency are not scourges, but MLM coins and air coins that are harming the people.

IV What exactly can blockchain bring to us

I don’t quite understand this. After all, I’m only a student and haven’t had a deep understanding of this aspect. If you If you want to know, you can check online. It will be good for you to learn more.

VI This article summarizes the nine major benefits that blockchain technology brings to enterprises

The launch of Bitcoin, the first application of blockchain in 2009, transformed blockchain from theoretical application to Transformed into real-world applications, it proves that this digital distributed ledger technology actually works. Since then, many enterprise organizations have been testing how to make blockchain work for them.

Now, well-known companies, government organizations and non-profit entities are also trying to use blockchain to improve existing processes and enable new business models.

Blockchain’s value stems from its ability to share data between entities in a fast and secure manner—without any entity being responsible for protecting the data or facilitating transactions.

"This is a transaction ledger with unique characteristics that help solve problems in our systems and processes," says U.S. University Information Technology &explains Ayman Omar, associate professor in the Department of Analytics and researcher at the Kogod Center for Cybersecurity Governance.

From Maoqiu Technology’s perspective, blockchain and its features can, in fact, help enterprises in a variety of ways – whether they use a public blockchain network or choose a private or permissioned zone-based one. Blockchain applications.

Maoqiu Technology The following are the main advantages of blockchain:

Blockchain creates trust between different entities where trust does not exist or is unverified. As a result, these entities are willing to engage in commercial transactions involving transactions or data sharing that they might not otherwise do, or would require an intermediary to do so.

The realization of trust is one of the most promising advantages of blockchain. Its value is evident in early blockchain use cases that facilitate transactions between entities that are not directly related but still need to share data or make payments. Bitcoin, and cryptocurrencies in general, are prime examples of how blockchain enables trust between participants who do not know each other.

Daniel Field, Head of Blockchain at UST Daniel Field, Head of Blockchain at UST, a global provider of digital technologies and services, explains that when there is no central actor facilitating trust, blockchain The chain has truly proven its value.

Thus, in addition to enabling trust when participants lack trust because they don’t know each other, blockchain can enable data sharing in an enterprise ecosystem where no single entity is solely responsible.

Supply chain is a good example. Multiple businesses—from suppliers and transportation companies to manufacturers, distributors, and retailers—want or need information from others in the chain, but no one is responsible for facilitating the sharing of all this information. Blockchain solves this problem with its decentralized nature.

The security of blockchain-enabled systems is another major advantage of this emerging technology. The enhanced security provided by blockchain stems from how the technology actually works. Blockchain creates an immutable record of transactions through end-to-end encryption, which keeps fraud and unauthorized activity at bay.

Additionally, data on the blockchain is stored in a computer network and is nearly impossible to hack (unlike traditional computer systems that store data in servers). At the same time, blockchain can limit access by anonymizing data and requiring permissions, solving privacy issues better than traditional computer systems.

Blockchain can also reduce costs for companies, increase the efficiency of processing transactions, and reduce manual tasks such as aggregating and modifying data, as well as simplifying reporting and auditing processes.

Experts point out that financial institutions are usingBlockchain will significantly reduce costs, explaining that the ability of blockchain to simplify clearing and settlement directly translates into process cost savings. More broadly, blockchain helps businesses cut costs by eliminating the middlemen — vendors and third-party providers — that traditionally provide the processing that blockchain can do.

By eliminating intermediaries and replacing remaining manual processes in transactions, blockchain can process transactions faster than traditional methods. In some cases, blockchain can process transactions in seconds or less. However, times may vary.

How quickly a blockchain-based system can process transactions depends on a variety of factors, such as the size of each data block and network traffic. Nonetheless, experts have concluded that blockchain generally outperforms other processes and technologies in terms of speed. In one of the most prominent applications of blockchain, Walmart used the technology to track the origin of mango slices in seconds—a process that previously took seven days.

Walmart’s use of blockchain isn’t just about speed; it’s also about the ability to trace the origins of these mangoes and other products. This allows retailers like Walmart to better manage inventory, respond to issues or questions, and confirm the history of their merchandise.

If a specific farm has to recall its products due to contamination, retailers using blockchain can identify and remove products from that specific farm while selling their remaining products. According to experts, blockchain can help trace the origin of various items such as pharmaceuticals to confirm that they are legal as opposed to counterfeit and organic items to confirm that they are indeed organic.

Immutability simply means that a transaction cannot be changed or deleted once it is recorded on the blockchain. On the blockchain, all transactions are timestamped and date-stamped, so there is a permanent record. Therefore, blockchain can be used to track information over time, allowing for safe and reliable auditing of information.

For example, Omar pointed to Sweden's use of blockchain to digitize real estate transactions to track property ownership even as they change hands as an example of this benefit.

Experts say blockchain could enable unprecedented personal control over one’s digital data. "In a world where data is a very valuable commodity, this technology essentially protects the data that belongs to you while allowing you to control it," said Michela Menting, research director at ABI Research.

Personal and Individual organizations can decide what digital data they want to share, with whom and for how long, and enforce restrictions through blockchain-enabled smart contracts.

Leaders across multiple industries are exploring and implementing blockchain-based systems to solve tough problems and improve long-standing cumbersome processes.Law. Field cited the use of blockchain to verify job seeker resume information as an example of such innovation. Research consistently shows that a large percentage of people falsify their resumes, leaving hiring managers with the time-consuming task of manually verifying information.

But a pilot program that allows participating universities to put data about their graduates and degrees awarded on the blockchain, which can then be accessed by authorized hiring managers, could help address both Question - Get to know the truth and get to the truth quickly and efficiently.

Executives need to carefully consider where they make blockchain investments, experts say.

They emphasize that the real value of blockchain lies in its use in areas where traditional databases do not work and where there is no central control or trust.

“If there’s a high level of trust, blockchain has no problems to solve. But the less visibility you have or the possibility of corruption, that’s where you have a bigger use case. That’s what blockchain Where chain becomes the solution,” Omar said.

Blockchain-based applications could also be paired with artificial intelligence, machine learning or some other decision-making layer, he said.

However, experts still believe that blockchain will bring disruption and business transformation—even if the revolution doesn’t happen anytime soon.

It’s important to understand that there’s a lot of hype around blockchain, and while it’s revolutionary in theory, it’s not going to change society today,” Mentin said. “Maybe from now on It will appear in 10 to 20 years, but this is not a short-term technology. ”

VII What should the phenomenon and application of blockchain look like?

1. The revolution of blockchain

Until the 7th year after the emergence of Bitcoin At the beginning of the year, its underlying core technology blockchain began to be familiar to people. With the wealth effect caused by Bitcoin’s multi-million-fold increase, blockchain has become more and more popular. Its value is widely recognized and is generally considered It is the core technology leading the fourth industrial revolution.

In 2018, Xu Xiaoping, a well-known angel investor, raised his arms and shouted: "The blockchain revolution has arrived! Embrace this revolution! "One stone stirred up a thousand waves, and soon the official blockchain learning book was launched online. Official media interpreted it as a wave of entrepreneurship and recruitment. In 2019, blockchain was officially designated as "an important breakthrough for independent innovation in core technology." .

Under this situation, blockchain has become an out-and-out "new trend", and blockchain application has become a keyword. It has significant advantages in optimizing business processes and building trustworthy systems. , how to use these advantages of blockchain technology to empower the real economy?

Not only blockchain project parties are trying, but Chinese Internet giants represented by BAT, China Merchants Bank, Bank of China, safety InsuranceAll walks of life, including the financial system and mobile operators represented by the blockchain, are actively pursuing "blockchain+". Overseas, it is also in full swing, with Facebook, Goldman Sachs, JPMorgan Chase, etc. all actively promoting it.

2. Blockchain+

On August 10, 2018, Tencent issued the first blockchain electronic invoice. As of July 3, 2020, invoices were issued Volume reaches 25 million. Blockchain electronic invoices have the advantages of simple invoicing, on-demand supply, low cost, high efficiency, and anti-counterfeiting. Tencent Blockchain quickly occupied the market with first-mover advantages in blockchain + government affairs and blockchain + taxation.

Ant Financial, owned by Alibaba, began to deploy blockchain as early as 2015. So far, Ant Blockchain has open alliance chain, BaaS platform and other products covering dozens of application scenarios. It has reached on-chain cooperation with many well-known global companies such as Intel, Jingdezhen Porcelain, and Bayer. The Internet also entered the blockchain very early and launched blockchain games, blockchain certificate storage and other services. Currently, the number of certificates stored on the chain has exceeded 100 million.

In 2019, the scale of China's blockchain industry alone reached 1.2 billion yuan. Data from the research institution Research and Markets shows that the output value of blockchain technology in the telecommunications field will surge from 4.66 million US dollars in 2018 to 2023. 993.8 billion US dollars in the year. Against this background, 2020 will usher in multiple policy benefits.

1. Officials have included blockchain into the scope of new infrastructure and new technology infrastructure;

2. Hunan released the "Three-Year Action Plan for the Development of the Blockchain Industry in Hunan Province" ( 2020-2022)";

3. Guangzhou launched the "Implementation Opinions of Guangzhou on Promoting the Innovation and Development of the Blockchain Industry (2020-2022)";

4. Beijing issued the "Beijing Blockchain Innovation and Development Action Plan (2020-2022)";

5. Jiangxi launched a blockchain service hall online;

6. Wuhan A special event for the transformation of blockchain technology scientific and technological achievements will be held;

7. The Chongqing Smart Expo Blockchain Application Innovation Competition plans to invest a huge amount of 50 million yuan as investment incentives.

However, although the implementation of blockchain in financial, government affairs, public welfare, games, agriculture, manufacturing, medical care, copyright and other physical fields has achieved remarkable results, it has also played an active role in fighting the new crown epidemic. role.

However, due to the influence of the general environment, more funds, resources, and attention have been attracted to the direction of blockchain empowering the real economy, but the core native applications of blockchain have been ignored.

3. Blockchain native applications

The Internet has opened an era of information explosion, and blockchain will bring a future where value flows freely. In today's global economic and financial system, affected by many factors such as ideology, cultural systems, business models, and technological levels, the cost of value transfer is high and the efficiency is low, especially in cross-border payment scenarios.

In the future blockchain era, value transfer will be like information transfer: global, instant, free, and equally enjoyed by everyone. All offline assets such as stocks, securities, identities, and real estate can be freely converted on the chain.

Moreover, the impact of blockchain technology has far exceeded the technical category itself. It is also an idea. The soul of blockchain lies in consensus. In the era of blockchain, truly powerful vitality will be born in community consensus and application implementation, and community and consensus will become the main body and soul of the industry.

In a community with consensus, individual energy and value will be fully stimulated, offsetting the fission effect of traditional centralization, breaking the original solid underlying structure, and reshaping new business and social values.

Therefore, blockchain native applications should be based on community and consensus, give individuals a path to realize their value, and be able to maximize the application ecosystem that stimulates individual energy and creativity, ultimately breaking monopoly and forming Decentralized free value exchange network.

Individual energy and value are multi-dimensional and highly subjective. These blockchain model designs obviously cannot fully stimulate individual energy, and are even far from it.

Native applications that truly conform to the spirit of blockchain should be grand and comprehensive in application model design, taking into account all online and offline value-creating behaviors of individuals for personalized use by individuals. , each individual’s areas of expertise are different.

Borrowing from the Pareto optimal solution theory, each individual's energy can be maximized to maximize the energy of the whole, and only then can the original centralized business model be broken and a free flow of global individuals be formed. A peer-to-peer value transmission network builds a new decentralized business infrastructure, changes the value creation and delivery model, and reshapes the values ​​of the entire society.
