(2) Extended reading on the application of blockchain in real life:

Blockchain is far more than just a technology, it involves What comes across is the spirit of “multi-party collaboration”. In modern society, many things must rely on everyone's cooperation to achieve the effect of 1+1>2, but in cooperation, we need to try our best to avoid problems such as "information asymmetry."

Therefore, alliance members jointly keep accounts, share data, and make everything public to eliminate "information asymmetry" to protect everyone's interests and allow the business environment to develop healthily. If you do things honestly, you will get the benefits you deserve. If you cheat, it will be known to everyone and criticized by thousands of people. Technology is the foundation that helps realize this model. This is the more important "blockchain thinking".

IV Application aspects of blockchain

The main application scope of blockchain includes: digital currency, transaction settlement of financial assets, digital government affairs, certificate deposit and anti-counterfeiting data services and other fields. Blockchain is a database technology that links data blocks in an orderly manner. Each block is responsible for recording a file data and encrypting it to ensure that the data cannot be modified or forged.

Blockchain is essentially a distributed database system that uses cryptography technology for multi-party participation, joint maintenance, and continuous growth. It is also called a distributed shared ledger. Each page in the shared ledger is a block, and each block is filled with transaction records. The anonymity, decentralization, openness, transparency, and non-tamperability of blockchain technology make it highly favored by enterprises and has gained More extensive application attempts.

Blockchain application scope 1. Financial field

Blockchain can provide a trust mechanism and has the potential to change the financial infrastructure. Various financial assets such as equity, bonds, bills, warehouse receipts, fund shares, etc. It can be integrated into the blockchain technology system and become a digital asset on the chain, which can be stored, transferred and traded on the blockchain.

The decentralization of blockchain technology can reduce transaction costs and make financial transactions more convenient, intuitive and secure. The combination of blockchain technology and the financial industry will inevitably create more and more business models, service scenarios, business processes and financial products, thereby bringing more impact to the development of financial markets, financial institutions, financial services and financial formats. . With the improvement of blockchain technology and the combination of blockchain technology with other financial technologies, blockchain technology will gradually adapt to large-scaleApplication of simulated financial scenarios.

2. Public service field

Traditional public services rely on limited data dimensions, and the information obtained may not be comprehensive enough and have a certain lag. The non-tamperable nature of the blockchain makes the digital certification on the chain highly credible. It can be used to establish new authentication mechanisms in the fields of property rights, notarization and public welfare, and improve the management level of public services.

Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain to meet the privacy protection of project participants and other relevant laws and regulations. Under the premise of requirements, public disclosure will be made conditionally to facilitate public and social supervision.

3. Information security field

Using the traceability and non-tampering characteristics of blockchain, we can ensure the authenticity of data sources and ensure the non-forgery of data. Blockchain technology will fundamentally change information Security issues of the propagation path.

Blockchain is reflected in the following three points in the field of information security:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of blockchain will make Hackers are at a loss as to what to do. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.

4. Internet of Things field

Blockchain + Internet of Things can allow each device on the Internet of Things to operate independently, and the information generated by the entire network can be protected through smart contracts in the blockchain.

Security: Traditional IoT devices are highly vulnerable to attacks, data loss and maintenance costs are high. Typical information security risk issues for IoT devices include low firmware versions, lack of security patches, permission loopholes, too many device network ports, and unencrypted information transmission. The blockchain's consensus mechanism for network-wide node verification, asymmetric encryption technology and distributed data storage will significantly reduce the risk of hacker attacks.

Trustability: The traditional Internet of Things is managed and controlled by a centralized cloud server. Due to the security of the device and the opacity of the centralized server, it is difficult to effectively protect user privacy data. The blockchain is a distributed account book. Each block is interconnected and has its own independent working ability, ensuring that the information on the chain will not be tampered with at will. Distributed ledgers can therefore provide trust, ownership records, transparency and communication support for the Internet of Things.

Effectiveness: Limited by cloud services and maintenance costs, the Internet of Things is difficult to achieve large-scale commercial use. The traditional Internet of Things realizes communication between things through centralized cloud servers. The disadvantage of this model is that as the number of access devices increases, the server faces more load, requiring enterprises to invest a lot of money to maintain the normal operation of the IoT system.

Blockchain technology can directly realize point-to-point transactions, omitting the labor expenditure of other intermediaries or personnel, which can effectively reduce the costs incurred by third-party services and maximize benefits.

5. Supply chain field

The supply chain consists ofIt consists of many participating entities, and there is a lot of interaction and collaboration. Information is stored discretely in their own systems, lacking transparency. The lack of smooth information makes it difficult for various participating entities to accurately understand the real-time status and existing problems of related matters, affecting the collaborative efficiency of the supply chain. When disputes arise between parties, it is time-consuming and laborious to provide evidence and pursue accountability.

Blockchain can make data open and transparent among various entities, thereby forming a complete, smooth, and non-tamperable information flow throughout the entire supply chain. This can ensure that all entities promptly discover problems arising during the operation of the supply chain system and find targeted solutions, thus improving the overall efficiency of supply chain management.

6. Automotive Industry

Last year announced a partnership using blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, and drive” process. Future customers choose what they want The rented car enters the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain updates the information simultaneously. This is not an imagination, for car sales and car registration Said, this type of process may also develop into reality.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easy. Emerging Blockchain Chain startups believe that blockchain technology can make this process more secure and automated than any previous solution. At the same time, blockchain startup Chain is working with Nasdaq to enable private companies through blockchain. Equity transfer

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision. Since blockchain technology can ensure the transparency and immutability of information, it is very important to the government. The implementation of transparent management plays a great role. There is a certain degree of information opacity in government project bidding, and enterprises also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information cannot be tampered with and can ensure the transparency of information nature, forming a common trust between competitors who do not trust each other. It can also arrange subsequent smart contracts through the blockchain to ensure the construction progress of the project and prevent the growth of corruption to a certain extent.

There are many more applications of blockchain technology, and this is just a fulcrum of blockchain applications. In the future, blockchain technology will be applied everywhere

IV Blockchain can be applied in Which aspects

I have seen your question, so, in what aspects can blockchain be applied? The editor will answer it for you below.

A: Bitcoin is the first concrete application of blockchain. It was proposed in a paper in 2008 by a person or a group of people. Bitcoin uses blockchain to digitally send Bitcoins, The name of BitCoin is Bitcoin, which does not require the intervention of a third-party middleman.

But Bitcoin is not the only application of blockchain, as follows:

1. Financial field:The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

2. Internet of Things and logistics fields: Blockchain can also be naturally combined in the fields of Internet of Things and logistics. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.

3. Public service field: Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields. However, the centralized nature of these fields also brings some problems. It can be used to distinguish Blockchain to transform.

4. Digital copyright field: Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership

< p>5. Insurance field: In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims.

6. Public welfare field: The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

The above is for your reference only, I hope you can adopt it, thank you!

VI What are the actual application scenarios of blockchain now?

The actual application scenarios of blockchain now include:

1. Traditional information sharing The pain points

Either a unified center publishes and distributes information, or regular batch reconciliation between each other (typically once a day). For time-sensitive information sharing, it is difficult to achieve real-time sharing. .

The two parties sharing information lack a mutually trusting communication method, and it is difficult to determine whether the information received was sent by the other party.

2. Blockchain + information sharing

First of all, the blockchain itself needs to maintain the data consistency of each node, and it can be said to have its own information sharing function; secondly, Real-time problems can be realized through the P2P technology of blockchain; finally, using the immutability and consensus mechanism of blockchain, a safe and reliable information sharing channel can be constructed.

Okay. You may have this question: To solve the above problem, I can build an encrypted channel myself without using blockchain technology! But I want to say that since blockchain technology can solve these problems and it is very convenient to add nodes, why not use blockchain technology before you have built a safe and reliable information sharing system?

3. Application cases

Let’s take Tencent’s own application—Public Welfare Person Searching Chain—to illustrate the value of blockchain in information sharing. Bitcoin solvedRegarding the issue of trust in currency issuance and accounting, let’s take a look at how Bitcoin solves the above two problems one by one.

The problem of spam issuance: Bitcoins can only be obtained through mining, and the total number of Bitcoins is 21 million. The problem of currency spam issuance is solved in the issuance process; Ledger modification problem: Bitcoin transaction records solve the ledger modification problem through chain storage and a decentralized global node network.

Chain storage can be simply understood as: the blocks that store records are connected one to another, forming a chain; the records of all blocks except the first block contain the calibration of the previous block. Verification information, changing the information of any block will cause subsequent block verification errors. Because of this correlation, other blocks cannot be inserted in the middle, so it is difficult to modify existing records.

VII Where is blockchain technology mainly used?

From a technical perspective and an architectural perspective, I will tell you in layman’s language some of my understanding of blockchain. .

What exactly is blockchain? Block chain, in a word, blockchain is a storage system, and the storage system is more detailed. Block chain is a distributed storage system without an administrator, and each node owns all data.

What do common storage systems look like?

As shown in the picture above, the bottom is data, and data can be written above. A space stores data, a software manages the data, and provides an interface to write data. This is the storage system. For example, MySQL is the most common storage system.

What problems are common in ordinary storage systems? There are at least two common problems

The first is the problem of non-high availability, where data is dangerous if it exists in one place. In technical terms, the data is not highly available.

The second problem is that it has a single point of writing, and there is only one writing point. In technical terms, it is a single point of control.

How do ordinary storage systems usually solve these two problems?

In fact, MySQL can do a dual-master master-slave synchronization. Two nodes can write at the same time. If you want to build a multi-machine room and multi-active data center, in fact, multi-machine room and multi-active data center also requires data synchronization. What should be emphasized here is that multi-point writing often leads to consistency issues of write-write conflicts. Taking MySQl as an example, assuming that the attribute of a table is an auto-increment ID, then the data in the database is now 1234, then one of the nodes When writing, a piece of data is inserted, it may become 5. Then these 5 pieces of data are synchronized to another master node. Before the synchronization is completed, if another writing node also inserts a piece of data, it will also generate A piece of data with an auto-incrementing ID of 5 is obtained. Then, after generation, synchronize to another node, and then when the synchronized data arrives, it will conflict with the two local 5s, and the synchronization will fail, which will cause write consistency conflicts.question. This problem will occur if there are multiple writes.

How to ensure consistency when writing multiple points?

Weixin's "Swan Master Class" will give you more technical work

Ⅷ Which fields are suitable for blockchain to be used in?

The first one, information security industry.
The second one is the bill business field
The third one is the payment and settlement business.
Fourth, identity/account authentication business.
Fifth, each node participating in the maintenance of the proof of equity blockchain can obtain a complete data record. Using the characteristics of reliable and collective maintenance of the blockchain, the rights of the owner of the equity can be confirmed.
Blockchain technology is really powerful. With the advancement of the times, this technology may change the development direction and trend of the financial industry, and because the blockchain technology itself has large capacity, high-speed computing, security, and convenience And other characteristics have laid a strong foundation for the advancement and popularization of technology.

ⅨWhat are the application scenarios of blockchain?

I have seen a lot of information about blockchain on the soon-to-be-launched blockchain. Blockchain will make the information Internet more valuable. With the transformation of the Internet, Kuaishanglin has accumulated a lot of experience in these technologies and has made great efforts in Internet finance. Go online soon.

X What are the application scenarios of blockchain technology?

Blockchain technology has various application scenarios. Once popularized, the entire society will receive huge benefits.
1. Financial Services
The application of blockchain in the financial field has long been spread and is not a new thing. All over the world, the application of blockchain in financial technology has been widely concerned and highly valued.
In mainland China, ChinaUnionPay signed a strategic cooperation agreement on mobile payment with Bank of China in early 2018 and explored cooperation in the field of blockchain. Later, it cooperated with JD.com to jointly launch the blockchain-based "Internet Financial Payment Security Alliance Risk Information Sharing (Distributed Query) )platform".
In Hong Kong, China, the Hong Kong Monetary Authority was one of the first regulators to launch a sandbox to support financial innovation experiments including blockchain technology; the Hong Kong Monetary Authority also joined hands with the banking industry to launch "Trade Linkage" (eTradeConnect), this is the Hong Kong banking industry’s first large-scale trade finance information sharing platform that applies blockchain technology.
2. Judicial evidence storage
On September 18, 2018, the Hangzhou Internet Court was officially launched on the blockchain, becoming the first court in the world to use blockchain for trials.
It is understood that the complainant can submit electronic evidence such as the contract, rights protection process, service process details, etc. online through the online complaint portal, and the nodes on the chain such as the notary office, judicial appraisal center, CA/RA agency, and court will jointly witness it. , joint endorsement, providing one-stop service for prosecutors. The Internet Court of Hangzhou, Zhejiang Province publicly pronounced its judgment on a dispute over infringement of the right to disseminate work information online, and for the first time confirmed the legal validity of electronic data stored using blockchain technology.
3. Intellectual property rights
Blockchain and related distributed ledger technologies provide the possibility for the protection and registration of intellectual property rights and as evidence during the registration stage or court litigation stage. These technologies can also speed up the protection and registration process of the above-mentioned intellectual property rights in a cost-effective manner.
4. Logistics field
In early 2018, Cainiao and Tmall International jointly announced that they have used blockchain technology to track, upload, and verify the full logistics link information of cross-border imported goods.
After all nodes in the logistics chain are connected to the blockchain, goods can be traced from the manufacturer to the consumer, forming a complete chain; the more missing links a product has, the higher the probability that it will be exposed as a fake or shoddy product. big.
5. Electronic Invoice
On August 10, 2018, Shenzhen Guomao Revolving Restaurant issued the country’s first blockchain electronic invoice. It is understood that this blockchain electronic invoice issued by Shenzhen It is led by the Municipal Taxation Bureau and Tencent provides the underlying technology and capabilities.
Different from traditional electronic invoices and simple electronic invoices uploaded to the chain, this blockchain electronic invoice combines "fund flow and invoice flow" into one, combining invoice issuance with online payment, and opening up the invoice application process. The entire process of collection, invoicing, reimbursement and tax filing.
In addition to the above fields, the blue ocean application prospects of blockchain are broad. In the future, the application and development of new technologies will emerge in all walks of life, and blockchain will flourish.
