① What are the actual application scenarios of blockchain now?

The actual application scenarios of blockchain now are:

1. Traditional The pain points of information sharing

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

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 solves the problem 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 spam issuance of currency 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.

② What 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, Kuaishang Online has accumulated a lot of experience in these technologies and has made great efforts in Internet finance. Go online soon. Through research, it is concluded that blockchain will greatly improve the current life scenes. In which scenarios blockchain can be applied, I will list some answers here for reference only:

③ What are the specific application scenarios of blockchain?

Taking the tourism industry as an example, blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, Credit consumption management, tracking of professional certificates and qualifications of pilots, hotel and airline loyalty programs, reservation management, and consumption points management are several application areas

In addition, the development of blockchain will not Few relevant top domain names have been registered, which has had a relatively large impact on the domain name industry

In addition, blockchain is also used in finance, games, entertainment and other fields

④ Blockchain Application aspects

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 blockchainBy combining technology with other financial technologies, blockchain technology will gradually adapt to the application of large-scale 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 expenditures of other intermediaries or personnel, and can effectively reduce the costs incurred by third-party services and implementMaximize current benefits.

5. Supply chain field

The supply chain consists of many participating entities, with a large amount of interaction and collaboration. Information is discretely stored 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 among 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

⑤ What are the current blockchain applications? Application Scenarios

1. Blockchain and finance support supply chain finance and alleviate the financing problems of small and medium-sized enterprises. 2. Blockchain and copyright protection, from rights confirmation to rights protection, effectively reduce the time from rights confirmation to rights protection. The time cost required for rights protection will open up the entire process of copyright protection. 3. Blockchain and cultural entertainment will promote the formation of a new cultural industry value network. Represented by the game industry, it will change the current opacity of the industry and the weak voice of consumers. The current situation of poor value circulation. 4. Blockchain and education, integrating industry and academia, and encouraging learning to excel, protect the academic copyright of what you learn and improve the learning community. 5. Blockchain and medical health, establish a digital medical treatment and smart medical system based on blockchain, reconstruct the medical insurance system, and ensure drug traceability. 6. Blockchain and government affairs, government affairs processes are open and transparent, simplify taxation, resolve electronic invoice problems, and form a business environment with a stable trust foundation. 7. Blockchain and justice, establishing identity authentication, protecting personal information security, and supervising law enforcement
