Blockchain in different countries

1. Globally, governments have different attitudes towards blockchain and blockchain assets, but on the whole, they are still in the exploration period
European and American countries are actively monitoring. Germany is the first country to recognize bitcoin and other digital assets as private property. The US CFTC (US Commodity Futures Commission) has identified bitcoin as a commodity. The state of New York has issued three bitlicenses
the situation in Asia is different. Japan actively supports it. In April this year, Japan implemented the payment services act, officially recognizing bitcoin as a legal payment method
South Korea is actively monitoring. In July, South Korea's "bitcoin Regulation Act" came out, setting a threshold of 500 million won for investors
China has strict supervision. In September, the people's Bank of China and other seven ministries and commissions jointly issued the "notice on preventing the financing risk of token issuance", which stipulates that in China, trading platforms shall not engage in the exchange business between legal tender and "virtual currency".

2. The world blockchain conference, a semiannual world instry event in the field of blockchain, aims to build an international platform for global blockchain related instries to interconnect, share and co govern, and create a win-win situation.

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

4. Patents have always been controversial in the field of cryptocurrency and blockchain, because most projects are built on the premise of decentralization and open source. It is for this reason that the concept of intellectual property (IP) is highly controversial
for this purpose, the following search terms are used to collect the website data of the World Intellectual Property Organization (WIPO): blockchain, blockchain, bitcoin, virtual currency, virtual currency, digital currency, digital token and smart contract
the analysis found that although the price of bitcoin plummeted, 2018 was the year with the most patents approved, and records showed that at least 1060 patents were published ring this period

971 items were approved in 2017. In that year, bitcoin began trading at $998, reaching an all-time high of $19666 in December
according to the data, patent approval started to take off in 2012, and it remained at the same level until 2015. So far this year, the World Intellectual Property Organization has granted 242 patents related to cryptocurrency or blockchain
China ranks first with 790 patents
followed by the United States, which approved 762 patent applications. South Korea and Australia followed, 161 and 132 respectively. The UK is the only European country in the top 10 with 36 approvals

the companies on the list are mainly technology giants and financial service companies, such as IBM (119 items), MasterCard MasterCard (111 items), coinplug (84 items) and Alibaba (60 items)< Among them, Yao Qian, director of the digital currency Research Institute of the people's Bank of China, has obtained 92 patents.

the most difficult one-on-three win,
the computer player said on the screen:
you are a living person,
and I am just a computer program,
what can you be proud of when you win?!

the definition of blockchain

in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

there are many channels to learn blockchain

① you can buy some books related to blockchain, learn some knowledge related to blockchain, take notes in your spare time, and consult relevant information

② watch some videos of blockchain on the Internet, the contents of which are easy to understand, with relevant examples, It's also a very good way to learn

③ you can take part in some offline blockchain learning exchange meetings, or take part in some training courses, and some teachers will answer questions for you

to sum up,

all roads lead to Rome. There are many channels to learn blockchain, and the best one is suitable for you

7. China also leads the rest of the world in the number of patent applications for blockchain procts. According to the financial times, among the patent applications for blockchain technology received by the World Intellectual Property Organization (WIPO) in 2017, China has the largest number of applications, far higher than the second and third ranked United States (91) and Australia (12)

8. There are a lot of blockchain alliances in the world, but in fact, there are no outstanding features. Generally, the so-called alliance is only an alliance within a certain instry, which is not extensive. Not enough. Now some international giants have begun to pay attention to blockchain technology, which is very gratifying
of course, blockchain has also been applied in real life, such as medical equipment corresponding to Ruitai coin, ant financial services, etc.

9. China also leads the rest of the world in the number of patent applications for blockchain procts. According to the financial times, China has the largest number of applications in the chain chain technology patent applications received by the World Intellectual Property Organization (WIPO) in 2017, which is far higher than the two or three ranking in the US (91) and Australia (12)
more patent knowledge. Remember the official account Dr inventor.
