⑴ Does the country support blockchain?

Legal analysis: As a new technology, blockchain is a new technology. Countries around the world have corresponding policies to support its development, with a wide range of radiation - — Judging from this year, more than half of the provinces and cities across the country have included blockchain in the 2020 government work report. In addition to first-tier cities such as Beijing, Shanghai, Guangzhou, and Shenzhen, central and western cities such as Gansu, Ningxia, and Xinjiang have also joined the blockchain technology research and application camp. Developed cities in the east continue to play a leading role in technological research and application innovation; cities in the central and western regions adapt to local conditions and combine new technologies to accelerate digital economic transformation. Strong support - this year the Central Bank, the Ministry of Transport, the State Administration of Foreign Exchange, the State Administration of Radio, Film and Television, the Ministry of Justice, the Ministry of Agriculture and Rural Affairs, etc., have respectively proposed the use of blockchain technology to accelerate the development of applications in various fields. Many other provinces and cities have also continued to introduce new policies, most of which are special support policies for blockchain. It is expected to build more industrial parks and open up more government application scenarios. The direction is clearer - there are clearer details under the general direction of blockchain assisting the transformation and upgrading of traditional industries and empowering the digital economy. Application scenarios such as transportation, agriculture, intellectual property, and certificate storage have become the first batch of experimental directions. In terms of government affairs, it is an important breakthrough and has been implemented. Beijing City’s “innocent approval”, Jiangxi Province explores “blockchain + undocumented handling”, Fujian Province implements the “on-chain government affairs” project, and Gansu Province accelerates the construction of “Digital Gansu”. ”, Shandong and Hainan are all committed to e-government and other fields. It is foreseeable that the future blockchain e-government scenario is worth looking forward to.

Legal basis: "Blockchain Information Service Management Regulations"

⑵ Does the country support tourism blockchain?

Supported
Blockchain is the futureThe country supports this trend and will not ban it now or in the future. Many people confuse the concepts of blockchain with Bitcoin and Ethereum. Blockchain is a public chain and a technology. It is distributed accounting, peer-to-peer, and cannot be tampered with. Solve the problem of trust between people, companies and companies, people and governments. It is an extension and upgrade of the Internet, so it is impossible to ban it.

⑶ It’s 2021. What will be the development trend of my country’s blockchain technology in the future?

Domestic blockchain technology has been conceptualized a few years ago and has now become widely used. It has been applied to actual business scenarios, such as the rice we eat, and the QR code on the packaging
Traceability is the application of blockchain technology. Companies like Shanghai Wanglian Technology entered the market earlier and are currently developing very well.

⑷ What disruptions does blockchain bring and why can it become a national strategy?

The disruptive characteristics of blockchain lie in the following four aspects: 1. Transparency. The data records of the blockchain system are transparent to the entire network nodes, and the update operations of the data records are also transparent to the entire network nodes. This is the basis for the trust of the blockchain system. Since the blockchain system uses open source programs, open rules and high participation, blockchain data records and operating rules can be reviewed and traced by nodes throughout the network, with high transparency.
2. Openness. The blockchain system is open. Except for the private information of the parties directly related to the data, which is always encrypted, the blockchain data is open to everyone (except for blockchain systems with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through public interfaces, so the entire system information is highly transparent.
3. Information cannot be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for systems such as private blockchains with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high
4. Decentralization. Decentralization is the most basic feature of blockchain, which means that blockchain no longer relies on central processing nodes and realizes distributed recording, storage and updating of data. In a traditional centralized network, attacking a central node can destroy the entire system. However, in a decentralized blockchain network, attacking a single node cannot control or destroy the entire network or more than 5% of the nodes in the network. It's just the beginning of gaining control. 2019 is the first year of commercial application of blockchain technology, and favorable policy incentives will make the development of blockchain technology more stable.
As the application of blockchain technology gradually penetrates into many fields such as digital finance and the Internet, everyone has a clearer understanding of the value of blockchain.
Blockchain has formed a global competition situation. All countries are seizing development opportunities, and China cannot lag behind; therefore, it is understandable that blockchain has become a national strategy.

⑸Is blockchain legal in China?

Blockchain investment currently has no clear laws to prove its legality in my country, and there is no law prohibiting the development of blockchain. However, blockchain investment is under the appearance of high returns. There are also great legal risks, so you need to be cautious.
First of all, due to the lack of supervision, most of its circulation and transaction forms are similar to the issuance and listing of securities, and there are behaviors of setting up exchanges for trading. First of all, due to the lack of supervision, most of its circulation and trading forms are similar to the issuance and listing of securities, and there is the practice of setting up exchanges for trading.
The transaction process and transaction results are not transparent, making it difficult to regulate the problem.
Legal basis:
Article 12 of the "Company Law of the People's Republic of China": Registration
The company is stipulated in the company's articles of association and registered in accordance with the law. A company can amend its articles of association and change its business scope, but it must register the change.
Projects within the company's business scope that are subject to approval under laws and administrative regulations must be approved in accordance with the law.

⑹ Is the blockchain legal?

Legal analysis: The blockchain is completely legal and compliant. Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is a shared database, and the data or information stored in it has the characteristics of "unforgeable" and "full traces". Features such as "traceability", "openness and transparency" and "collective maintenance".

Legal basis: "Blockchain Information Service Management Regulations" of the State Internet Information Office

Article 4 encourages blockchain industry organizations to strengthen industry self-discipline, establish and improve industry self-discipline systems and industry Guidelines for blockchain information service providers to establish and improve service specifications, promote the construction of industry credit evaluation systems, urge blockchain information service providers to provide services in accordance with the law, accept social supervision, and improve the professional quality of blockchain information service practitioners. Promote the healthy and orderly development of the industry.

Article 5: Blockchain information service providers shall implement information content security management responsibilities and establish and improve management systems for user registration, information review, emergency response, and security protection.

Article 6 Blockchain information service providers shall have the technical conditions suitable for their services. For information content prohibited by laws and administrative regulations, they shall have the ability to publish, record, store and disseminate information content in real time. and emergency response capabilities, and technical solutions should comply with relevant national standards and specifications.

⑺ What is the concept of blockchain? Is blockchain a scam? The most complete explanation of blockchain

What is the concept of blockchain?

On October 25, 2019, the country advocated the development of blockchain. Overnight, the blockchain concept became popular.

However, many people are hearing about blockchain for the first time.

So, what is blockchain?

MeLet’s take a look at it from an academic perspective:

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transactions. Information, used to verify the validity of its information (anti-counterfeiting) and generate the next block.

In fact, blockchain is essentially a decentralized database.

Is blockchain the same as Bitcoin? Blockchain is not Bitcoin. The first application of blockchain is Bitcoin.

What are the characteristics of blockchain? Now let’s take a look at several characteristics of blockchain:

1. Decentralization:

The most important feature of blockchain is decentralization. Blockchain systems are different. Based on a centralized database, it is not controlled by any person or entity. Through distributed storage, data is completely copied and distributed on multiple computers, and each node realizes information self-verification, transmission and management.

2. Non-tamperability:

The blockchain system also has the characteristics of non-tamperability. In the blockchain system, each node is the center and no information can be changed, not even the administrator can modify this information. The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. This situation is basically impossible, thus eliminating the possibility of fraud.

3. Publicity:

In a blockchain system, all nodes in the network can easily access information. The foundation of blockchain technology is open source. In addition to private information being encrypted, blockchain data is open to everyone. Anyone can query blockchain data and develop related applications through public interfaces, so the entire system information is highly transparent. .

4. Independence:

Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so there is no need for a third party whether in transaction or exchange of funds. of approval.

Based on consensus specifications and protocols, the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without any human intervention.

Let’s assume an environment: 6 people live in dormitory 188 of the university

There is a ledger in the dormitory for Xiao Li, who is good at calculation, to keep accounts.

In the beginning, when the dormitory was selling paper boxes and buying some public items, Xiao Li will record it in the account book. If Xiao Li wanted to enrich himself and made false accounts, there would be less money in the account books, but no one would know.

After all, there is already a general ledger room, who would have nothing to do to keep track of the ledgers?

However, one day, because Xiao Li took more, there were obvious errors in the account book. Now, he could no longer hide it, so Xiao Li had to admit his mistake and make up the money.

So, how to solve this problem?

If blockchain is used to solve the problem:

Everyone in the dormitory takes out a ledger, and every time a transaction occurs, everyone records it in their own ledger. , such problems will not arise, because everyone is keeping accounts and can see the transaction records and final results on the ledger.

Xiao Li can’t change, you can’t change, and neither can your lower bunk. No one can change it.

This is because the previous accounting model was a centralized accounting model, and the current accounting model is a decentralized accounting model, where everyone is the center and everyone is the accountant.

If someone wants to change it, it will obviously be ineffective if they only change the data on their own account book, unless they bribe three people.

So, is blockchain a scam?

With the emergence of the great benefits of blockchain, in a short period of time, the prices of blockchain-related assets have soared, and ordinary investors are becoming more and more interested in blockchain. And criminals have also taken aim at this. There are some criminals who wear the gorgeous cloak of "blockchain" and use the blockchain to commit fraud or issue digital currencies without permission, leading many people to think that the blockchain is a scam.

But in fact, it is not. Blockchain is just a technology. If it can be used well, it will benefit the public and promote the development of the industry.

In particular, the application of blockchain is very wide and can be applied to almost everything of value to human beings.

Medical field: For example, when you go to the hospital for medical treatment, you can directly check the previous medical treatment in your own database, which greatly saves medical resources and saves medical expenses for repeated examinations.

Food traceability: Do you know where the food on your table comes from? Which logistics team is transporting it? This information can be tracked using blockchain. It can provide us with a single source of truth.

Supply chain application: For example, when we buy a product on a certain product, it leaves the factory, goes to the distributor for logistics turnover, goes to the seller's store warehouse, and then reaches the consumer's hands. During these processes, if something goes wrong, only you will know about it, and others, especially consumers, will not.

Okay, about the districtThis is where I introduce the relevant knowledge about the concept of blockchain to you. I hope it can be helpful to you.

⑻ The future development prospects of blockchain

1. Blockchain has become the forefront of global technological development and opened up a new track for international competition. Blockchain will become a new key infrastructure to further accelerate the development of the digital economy, lead a new round of global technological and industrial changes, and become the "source" of technological innovation and model innovation. The world's major developed countries will further pay attention to blockchain technology, intensively introduce relevant policy plans, increase industrial support and guidance, and enhance the competitiveness of their country's blockchain technology and industry.
2. The digital currency bubble gradually cools down. With the spread and popularization of the concept of blockchain technology, more and more people will realize that Bitcoin is not the same as blockchain, and various air coins will be gradually eliminated. Blockchain technology innovation will return to a more rational track. Technical features such as decentralization, multi-party collaboration, and anti-calculation tampering will be highly valued by relevant industries. Some industries with strong innovation capabilities will continue to emerge with blockchain applications that have been transformed based on industry characteristics.

⑼ Why the country bans blockchain

What needs to be corrected is that the country prohibits transactions in digital virtual currencies such as Bitcoin, which are unregulated and have high financial risks. Blockchain is the underlying technology of Bitcoin. The country is supporting the development of blockchain technology, and local governments have introduced relevant support policies.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of applications. Data blocks generated by cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

Bitcoin is an online virtual currency. The concept of Bitcoin (BitCoin) was first proposed by Satoshi Nakamoto in 2009. It is a P2P digital currency.
