How many countries recognize blockchain

1. Legally, China only has restrictions on the issuance and speculation of currency in the blockchain, because a large amount of black money in China, such as those of corrupt officials, will be illegally obtained overseas by means of digital currency. If the blockchain digital currency is opened up and traded casually, it is estimated that China can not control the outflow of black money. Now the law encourages blockchain. In addition to legal currency, China encourages and supports other blockchain technologies.

2. On September 7, 2018, the Supreme People's Court of China announced the provisions of the Supreme People's Court on Several Issues concerning the trial of cases on the Internet (hereinafter referred to as the provisions). Article 11 stipulates that: "the electronic data submitted by the parties shall be collected through electronic signature, trusted time stamp, hash value verification, blockchain and other evidence If the authenticity can be proved by fixed and tamper proof technical means or by electronic forensics platform authentication, the Internet court shall confirm. " This is the first time that the Supreme People's court has made a judicial interpretation on the authenticity of electronic data deposited with blockchain technology, thus the legal effect of blockchain deposit has been confirmed
at present, a number of third-party right preservation platforms based on blockchain technology have emerged in China. The originator can use the electronic data provided by the platform as electronic evidence in case of right disputes.

3. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not 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 private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

4. Yes, it supports. There are many policies on record. You can see that there are also policies to encourage blockchain entrepreneurship. There are different preferential policies in different places

bitcoin:

is an electronic currency proced by open-source P2P software. Digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin."

bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. Since bitcoin was born with an algorithm, it was stipulated from the beginning that all bitcoins in the world would not exceed 21 million bitcoins. Because bitcoin is not regulated by the government, it is not subject to inflation constraints and external control

people use the computing power of CPU and CpG to "mine" to unlock the new bitcoin. To put it figuratively: bitcoin is equivalent to a gold mine created by people using computers. The setting of this gold mine is limited. The upper limit is 21 million bitcoin. People dig out bitcoin one by one just like miners using the principle of CPU computing

the principle of bitcoin, the distributed characteristics of P2P and the design without central management mechanism ensure that no institution can control the value of bitcoin or create inflation. This decentralization makes it a more secure and value preserving "virtual currency"

But in fact, netizens, as well as traders and investors of bitcoin, do not see one of the biggest drawbacks of bitcoin: bitcoin is not unique

What do you mean? We think that bitcoin is the only one with a cap of 21 million, which seems to have the function of preserving value. But the principle of bitcoin algorithm is not only applicable to "bitcoin", a kind of currency from Japan. Every computer engineer can develop the corresponding algorithm, make a man-made gold mine, and control its upper limit. In this way, every country, every region and every person can develop countless algorithms. Then the market will be full of virtual currencies such as "bitcoin a", "bitcoin B", "bitcoin C", "bitcoin D", and so on. By that time, who are you going to invest in? You can create your own currency

this hidden danger is not a dream. In fact, it has already started. You can log on bitcoin's official website in China. You will find that in addition to bitcoin, there is now another kind of thing called "Yuanbao coin". This is an algorithm similar to bitcoin developed by a Chinese development team. It also has the same upper limit. The same people can't control it and dig Yuanbao coin out through "mining"

if they can do this, I believe many computer workers can also write their own "Yuan Bao coin", "gold and silver coin", "China bitcoin" and "Shanghai bitcoin". Bitcoin, as the first code to appear, has no credit support from the Central Bank of any country. It has value only because of the scarcity of 21 million. In fact, this scarcity does not exist, because everyone can develop the virtual currency code, and then people from all over the world can mine it. So what's the price of bitcoin? There are limited kinds of metals on earth, so each metal has different value according to its quantity and scarcity. But the bitcoin like code in the network world is infinite. As long as people are willing, they can create unlimited kinds of bitcoin code. Tell me, is bitcoin still valuable

blockchain Technology:

the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database

the essence of blockchain is to achieve the goal of decentralization and disintermediation through a new generation of data technology, so as to transmit value more transparently and efficiently. This kind of point-to-point verification will proce a new network "basic protocol" which is different from TCP / IP in the Internet era

blockchain shows us a world in which all assets will be digitized. In a valuable Internet, the transfer of assets will be as fast, convenient and cheap as the transmission of information today

the significance of blockchain is not the wealth of digital currency, but the value transmission of its technology itself. Therefore, Ma Yun has repeatedly separated blockchain from digital currency, and stressed that the extent to which blockchain technology will change the world is beyond people's imagination

difference:

blockchain is a technology, based on blockchain technology, there can be many applications

bitcoin: is one of the most popular and well-known applications

7. At present, the state has not yet recognized
some time ago, the state specially cracked down on this virtual currency
so we should be cautious in investing in virtual currency

8. The simplest way for Xiao to buy currency is to buy it on Ouyi okex. It can get to the account quickly and operate foolishly. It is the largest trading platform in China at present and it is very convenient to use.
