1. What are the characteristics of blockchain?

There are five main technical characteristics of blockchain, namely: decentralization, information cannot be tampered with, openness and transparency, Collectively maintainable, reliable database. It can be used in many aspects, for example, let’s take a rental agency. In the past, the agency had information about the property and the tenants. Moreover, some unscrupulous agents would change the information at will, just to make money in the middle. More agency fees. And if a blockchain is built and applied in the rental field, then the property information will be filled in by the landlord, and the tenant's information will be filled in by the tenant. Note that once the information is filled in, it cannot be changed twice. So this is equivalent to removing the center of intermediary. Of course, we are just talking briefly. In fact, deploying such a blockchain is also very complicated.

2. What are the advantages of blockchain?

Decentralized, non-tamperable, convenient and efficient.
Blockchain is a distributed ledger technology that has the following advantages:
1. Decentralization: Blockchain is a distributed system that does not rely on any central organization or individual. This makes the blockchain more secure and stable, making it less likely to be destroyed or attacked.
2. Untamperable: Blockchain uses cryptography technology to ensure the security and reliability of data. Once the data is written to the blockchain, it cannot be tampered with. This makes blockchain very suitable for recording important transaction records or other data.
3. High efficiency: The distributed architecture of the blockchain enables it to quickly process a large number of transactions without relying on any centralized agency coordination. This makes blockchain very suitable for large-scale financial transactions or other data processing tasks.
4. Privacy protection: Blockchain can use anonymous accounts or other technologies to protect users' privacy, so that users do not need to worry about the leakage of their personal information when using the blockchain.
In general, blockchain has the advantages of decentralization, non-tampering, high efficiency, and privacy protection, so it has been widely used in finance, logistics, medical and other fields.

7. The future development prospects of blockchain will profoundly affect three aspects

It is still unknown how much technological impact blockchain will bring to the human world, but industry, academia and research generally believe that so far we have only seen the tip of the iceberg of the potential value of blockchain.horn! Blockchain technology will not only change technology and reshape industries, but will also shake the existing order, traditional rules and value systems of human society. As blockchain technology gradually matures, it is foreseeable that blockchain will show the following development trends.

Zero-knowledge proof

Blockchain is very transparent in nature. Any node running in the blockchain network can view and download all data stored in the ledger. Blockchain combines zero-knowledge proof technology to allow users and businesses to use private data to execute smart contracts without revealing specific data content.

Artificial Intelligence

Blockchain can serve as the foundation for decentralized markets and a coordination platform for various artificial intelligence components, including data, algorithms, and computing power. This could lead to new levels of innovation and use of artificial intelligence. Blockchain will also make such decisions more transparent, explainable and trustworthy. Since all data on the blockchain is public, artificial intelligence will become the basis for providing anti-counterfeiting and privacy protection.

Internet of Things

Blockchain can add a layer of accountability and security to IoT data, becoming the future driver of IoT efficiency, scalability and standardization By. For example, in healthcare, blockchain-enabled IoT devices will allow patients to control access to the data collected by these devices. This technology will make devices more resistant to cyberattacks and provide a detailed record of when another party accessed data. In supply chains, blockchain-based systems, powered by smart contracts, can automate payments based on specific conditions measured by IoT sensors.

The arrival of the blockchain era has revealed the future development trends of various industries, and the increasingly mature technology of blockchain has gradually entered a period of expansion. I believe that in the near future, it will definitely produce greater economic benefits for society.

8. Advantages of blockchain technology

1. Decentralization:
Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no center In addition to the self-contained blockchain itself, each node realizes information self-verification, transmission and management through distributed computing and storage. 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 The interface queries blockchain data and develops 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, which 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.

9. Characteristics of blockchain technology

The five basic features of blockchain technology are as follows:
1. Features of blockchain technology 1: Distributed database
Every party on the blockchain can access the entire database and its complete history. No single party controls the data or information. Each party can directly verify the records of its trading partners without the need for a middleman.
2. Blockchain technology feature 2: Peer-to-peer transmission
Communication occurs directly between peers, rather than through a central node. Each node stores and forwards information to all other nodes.
3. Blockchain technology feature three: Transparent anonymity
Any user with access to the system can see each transaction and its associated value. Each node or user on the blockchain has a unique address consisting of more than 30 letters and numbers, which is used to identify itself. Users can choose to remain anonymous or provide proof of their identity to others. The addition of the blockchain occurs at one of these addresses.
4. Blockchain technology feature four: Irreversibility of records
Once a transaction is entered in the database and an account is updated, the records cannot be changed because they are linked to every transaction record before them (hence the name "chain"). Various algorithms are used to ensure that records in the database are permanent, chronologically ordered, and accessible to all users on the network.All other nodes are accessible.
5. Features of Blockchain Technology Five: Computational Logic
The digital nature of the ledger means that blockchain transactions can be associated with computational logic and are essentially programmable. Therefore, users can set algorithms and rules that automatically trigger transactions between nodes.
Extended information:
Blockchain is a chain composed of blocks one after another. Each block stores a certain amount of information, and they are connected into a chain in the order in which they were generated. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes. These nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain. thing. Compared with traditional networks, blockchain has two core characteristics: data is difficult to tamper with and decentralized. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, and can help solve the problem of people's mutual distrust.
