❶ Advantages of Blockchain Technology Classification of Blockchain Technology

The development of Blockchain technology is becoming more and more prosperous with the continuous expansion of applications. This comes from The strong development momentum in response to the needs of various industries has led to rapid changes in blockchain technology, which has attracted more and more attention to the achievements of various industries. From professional technology to resources, they are constantly concentrated in this industry, thus allowing The development of blockchain technology has entered a new stage, and the impact of this development has also attracted much attention.

When talking about blockchain technology, Bitcoin has to be mentioned. Many people know that the electronic currency Bitcoin does not rely on the issuance of a specific monetary institution, but is generated through a large number of calculations by a specific algorithm. In fact, the core that truly supports Bitcoin is blockchain technology.

How does the invisible and intangible Bitcoin operate through blockchain technology? The interpretation circulated in the industry is that blockchain can be regarded as a technical solution for collectively maintaining reliable databases through "decentralization" and "trustlessness". In layman’s terms, this technology can be understood as a technology in which everyone participates in accounting. In the past, people used centralized servers to keep accounts, but in the blockchain technology system, everyone can participate in accounting and jointly identify Authenticity of records.

“Through this technology, even if there is no neutral third-party organization, two parties that do not trust each other can achieve cooperation. In short, the blockchain is like a ‘machine that creates trust’. "Bubi Company is a leading blockchain service provider in China. It has made many breakthroughs in the blockchain technology platform, can meet scenarios with tens of millions of users, and has the ability to quickly build upper-layer application businesses.

The blockchain technology used by all parties involved in recording and storing information adopts a decentralized distributed structure, which saves a lot of intermediary costs and can better ensure data security; at the same time, it cannot be tampered with Timestamps can effectively solve problems such as data tracking and information anti-counterfeiting.

Will it become the next trend of Internet finance?

Although blockchain emerged with Bitcoin, the derived value of this technology has transcended digital currency. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to allow digital assets to flow freely. What Bubi wants to do is to create a new technology and product - to realize real value circulation and bring the Internet to a new level. With the application of this technology, there will be no central organization when transferring assets, and direct transfer of assets between us can be achieved.

In the current international financial market, the U.S. Central Bank, Swiss Bank, and some insurance and futures companies are all competing to develop blockchain technology. Fang Liang introduced that in the Internet financial industry, blockchain technology will first affect the payment system and securities settlement.Financial infrastructure such as computing systems and transaction databases; later this technology will also be expanded to general financial services, such as credit systems, "anti-money laundering", etc.

“The payment and clearing system in the financial field will evolve towards decentralization. The electronic ledger supported by blockchain technology is a reliable system that is error-free and cannot be tampered with. Quan and others have a profound impact." Li Yan said.

Therefore, industry insiders believe that blockchain technology may be the next trend in the Internet financial industry. As the interconnection of all things deepens, Yang Tao, assistant director of the Institute of Finance, Chinese Academy of Social Sciences, also said that blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources, and will also promote the improvement of existing financial system rules. Build a shared and win-win financial development ecosystem.

Blockchain technology will affect many industries

“Blockchain technology has been widely used in the era of big data.” Li Yan said frankly that in addition to the Internet financial field, Blockchain technology has been applied in many fields and has shown great prospects.

For example, the healthcare industry has benefited greatly from blockchain technology. In reality, patient private information leaks often occur, and centralized database or file cabinet management in medical departments is no longer the optimal choice. Medical institutions are using blockchain technology to keep patients' private information confidential.

In addition, blockchain technology also has important legal implications. In some civil fields, it is often necessary to provide evidence to determine blame, and blockchain technology can record every step and help judicial authorities identify the specific responsible person.

“Especially in the field of assets, whether it is physical assets such as real estate and cars, or intangible assets such as health and reputation, this technology can be used to complete registration, transactions, and tracking. It can be said that any lack of Blockchain technology will be useful in all areas of trustful production and life."

The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted The new development of various industries, the impact of this 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 to see, expecting this brand-new technology to be used by various industries. Better benefit all industries.

❷ Advantages of blockchain technology

1. Decentralization:
Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control , in addition to the self-contained blockchain itself, through distributed accounting and storage, each node realizes information self-verification, transmission and management. Decentralization is the most prominent and essential feature of blockchain.
2. Openness:
The foundation of blockchain technology is open source. In addition to the private information of the parties to the transaction being encrypted, the data of the blockchain is open to everyone. Anyone can access it through the public Interface checkquery blockchain data and develop related applications, so the entire system information is highly transparent.
3. Independence:
Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties, and all nodes can Verify and exchange data automatically and securely within the system without any human intervention.
4. Security:
As long as 51% of all data nodes cannot be controlled, network data cannot be manipulated and modified at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.
5. Anonymity:
Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be carried out anonymously.
Digital China is a major development strategy clearly stated for the first time in the report of the 19th National Congress of the Communist Party of China. Digital technology applications represented by cloud computing, big data, and mobile Internet are no longer limited to the economic field, but have widely penetrated into public services, social development, and all aspects of people's lives, requiring macro coordination, overall control, and integrated development.
With the new round of technological revolution and industrial transformation continuing to deepen, the wave of digital economy is unstoppable on a global scale. Developing the digital economy has become a global consensus and is known as the key to opening the door to the fourth industrial revolution.
Adhering to the world-wide inclusive humanistic spirit of the University of Nice, always embracing changes, standing at the forefront, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of Nice's "Doctorate in Blockchain and Digital Economic Management" ( DDE for short) came into being.
This is the cornerstone to empower digital economy industry managers with a global vision and global integration thinking, integrate knowledge, intelligently operate the digital economy, promote the sustainable development of the industry, and contribute to a community with a shared future for mankind. Therefore, the DDE project will advance in collaboration with colleagues in the digital economy field.

What is blockchain technology? What are the core components of blockchain technology?

What is blockchain technology:
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block..
The core components of blockchain technology:
Blockchain mainly solves the trust and security issues of transactions, so it proposes four technological innovations to address this issue:
The first one is called distribution A type of ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction and can also jointly testify for it.
Different from traditional distributed storage, the uniqueness of blockchain distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally divides data into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and of equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node. [8]
No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.
The second one is called asymmetric encryption and authorization technology. The transaction information stored on the blockchain is public, but the account identity information is highly encrypted and can only be accessed with the authorization of the data owner. This ensures data security and personal privacy.
The third one is called the consensus mechanism, which is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.
The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be computing power, the number of shares, or other factors. A characteristic quantity that a computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. [8]
Taking Bitcoin as an example, it uses proof of work. Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
The last technical feature is called smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to implement it in some standardized insurance products.Automate claims settlement.
In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

What is the core layer of blockchain technology?

Chongqing Jinwowo Analysis: The consensus mechanism is the core of blockchain technology. The consensus mechanism largely determines the degree of mutual trust between nodes in the entire blockchain system, and also determines other users’ views on the blockchain. The degree of trust in online data

What is the core component of blockchain technology?

Analysis by Chongqing Jinwowo: Blockchain technology consists of three core technologies: consensus mechanism, common defense mechanism, and distributed storage.
The three core technologies are supported by machine trust, that is, through the support of network technology, breakthroughs in difficult problems such as point-to-point transaction, decentralization, non-tampering of recorded information, irreversible transactions, and information encryption are achieved through network technology support.

What is blockchain technology? What does blockchain technology mean?

The so-called blockchain technology, also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization. , open and transparent, allowing everyone to participate in database records.
Explained in layman’s terms: If the database is assumed to be a ledger, reading and writing the database can be regarded as a bookkeeping behavior. The principle of blockchain technology is to find out the fastest and best bookkeeping within a period of time. This person will keep accounts, and then send this page of information to everyone else in the entire system. This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.

What is blockchain technology?

Blockchain has been hyped up like crazy, but you know nothing about it!

Blockchain is a distributed database system participated by different nodes and an open ledger system.

It consists of a series of data blocks or data packets generated according to cryptographic methods, that is, blocks. Each block of data information is automatically timestamped, thus Calculate a data encryption value, that is, a hash value (hash).

Blockchain technology is essentially a distributed accounting technology. It allows everyone to have a real-time synchronized ledger in their hands, and every transaction that occurs in the entire network will have thousands ofTens of thousands of backups and synchronized records. When perpetrators attempt to tamper with ledger data, they must change the ledger in the hands of the majority of people to achieve their goal.
