Block chain will replace Alipay

1. blockchain is the biggest trend in the next decade
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date
the concept of blockchain can be traced back to the end of 2008. In the forum, a mysterious personage named "Nakamoto Tsung" published a paper "bitcoin: a peer-to-peer e-cash system" and proposed the concept of blockchain for the first time
on January 3, 2009, the first block of the blockchain was born, which is called the "Founding block"
almost with the birth of blockchain technology, bitcoin became the first thing to play its role. In the following years, bitcoin graally swept the world. In 2017, its crazy market made blockchain technology known to all
the idea of blockchain first appeared in the famous bitcoin open source project. In the process of its birth and development, bitcoin project draws on the technical achievements from digital currency, cryptography, game theory, distributed system, cybernetics and other fields. It can be said that bitcoin project is good at all. As its core supporting structure, blockchain technology is a remarkable innovation achievement
blockchain is a distributed database system with different nodes, which is an open ledger system<
three characteristics of blockchain
compared with the traditional centralized scheme, blockchain technology mainly has the following three characteristics:
the core idea of blockchain is decentralization
in the blockchain system, the rights and obligations between any node are equal, and all nodes have the ability to vote with computing power, Thus, the result recognized by more than half of the nodes is guaranteed. Even under serious hacker attacks, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
block chain's biggest subversive is the establishment of credit
the collective maintenance of blockchain can rece the cost
in the centralized network system, the maintenance and operation of the system depend on the operation and operation of platforms such as data center, and the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. Each node can verify the correctness of the results of other nodes' records while participating in the records, which improves the maintenance efficiency and reces the cost
in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival< Its development has gone through three stages
1. Brewing period: from 2009 to 2012, bitcoin and its instrial ecology are the main economic forms
2. Embryonic period: from 2012 to 2015, with bitcoin entering the public view, new wallet payment and remittance companies appeared, and blockchain economy spread to the financial field. The underlying technology of blockchain is constantly innovated. Blockchain technology is separated from bitcoin system
3. Development period: in 2016, we began to explore instry applications, and a large number of blockchain start-ups appeared. The popularity of ICO in 2017 has given blockchain unprecedented attention
"blockchain 2.0 era" is coming
the application service layer is the driving force for the sustainable development of blockchain, which is divided into three stages of application: 1.0, 2.0 and 3.0
programmable currency: blockchain 1.0 application
programmable currency is the digital currency represented by bitcoin, but it is not the legal tender of any country or region, and there is no government authority to provide guarantee for it
programmable Finance: blockchain 2.0 application& quot; Smart contract& quot; Using program algorithm to replace the concept of contract execution. This enables blockchain to expand from the original monetary system to the registration and transfer of equity, creditor's rights and property rights, the transaction and execution of securities and financial contracts, and even the financial fields of gambling and anti-counterfeiting
programmable Society: blockchain 3.0 application
blockchain is the core of value Internet, which can confirm, measure and store the property rights of information and bytes representing value in each Internet. It can not only record the transactions of the financial instry, but also record almost anything valuable that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the whole society
at present, the application of blockchain has begun to surpass bitcoin (blockchain 1.0), enter the era of blockchain 1.5, and transition to the financial field (blockchain 2.0)
in the next 3-5 years, blockchain may go beyond the financial field and enter the field of social notarization and intelligence (blockchain 3.0), including identity authentication, notarization, arbitration, audit, domain name, logistics, medical care, mail, visa, voting and other fields. Its application scope will be expanded to the whole society, and blockchain technology is likely to become a new technology& quot; All things are connected& quot; It's the lowest level protocol
at present, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Accompanied by more people's attention, "in the next 30 years, new technologies will be integrated into all aspects of traditional instries, and human society will turn upside down. No matter who you are, no matter where you are, all of us will be a part of this great change."
this is the current situation. Blockchain has given the post-90s an opportunity. However, if you want to control blockchain technology without being affected by negative factors, the most important thing is to have a clear understanding of it, whether it is regulators, researchers, speculators or bystanders
it's time to devote more energy to blockchain technology
in China, the average annual salary of blockchain positions has reached more than 300000, and that of some enterprises has reached more than 1 million. The monthly salary of blockchain instry graates in Beijing, Shanghai and other places has exceeded 20K! If the post-90s seize the bonus of the times, they may become the next Alibaba in the future! If you miss it, you may regret it for ten years.

2. Registering the WeChat official account for block chain links is not required, as long as it is over 18 years old. The official account of WeChat is an open self media platform, anyone can check in.
however, wechat now has strict supervision on the number of keywords of blockchain, digital currency and bitcoin, so we should pay attention to it when we publish articles. Bitcoin, wikilink, bitcoin cash and Ethereum, which use blockchain technology, were too hot and speculative last year, and the government didn't like them.

3. 1. First of all, different brands and different series of procts have different characteristics and advantages. There are obvious differences in proct design, after-sales warranty service and many other aspects
2. It is recommended to select the motherboard suitable for indivials according to the actual use needs, use environment, actual budget, and proct comparison of physical stores or online stores
3. It is recommended to consult the local entity dealers or other major e-commerce websites about the description and specific price of the corresponding plate type, and make a comprehensive judgment and selection according to their own needs. As for which proct is better, there is no unified standard.

4. This is theoretical, that's why people ask questions about mining with galaxy, but it's hard to be true! The difficulty of mining will graally increase, and it will be found that the input and output are not very different.

5.

at the beginning, when people heard the digital currency, they confused it with Alipay and WeChat. In fact, the digital currency is different from WeChat and Alipay. It is a kind of currency, and WeChat and Alipay are tools of payment, but also a means of payment. Therefore, digital money and Alipay and WeChat are essentially different things. To put it simply, Alipay and WeChat are a kind of purse, which can be paid by recharge, while the digital money is directly paid. p>

digital currency

and Alipay need to complete payment in the case of network, but digital money is different, even if there is no network, the digital money can still complete the payment. Not only that, WeChat and Alipay have "cash withdrawals" services, and cash charges are charged for collecting cash. Each charge is charged at 0.1% of the cash withdrawal amount, but the use of digital money can save part of the service charge. In this way, the use of digital currency can avoid the cost of "cash withdrawal" and save a lot of money for people. Of course, the benefits of digital currency are more than that

digital currency is very different from WeChat and Alipay. There are two ways to use it. One is to pay by mobile phone, the other is by credit card. The process of mobile payment is not difficult. You need to use the software called "digital RMB". When collecting and paying, you just need to slide up payment and down payment. Swiping the card is for the elderly. Although they are not very good at using smart phones, it is more convenient to use the card. You only need to touch the relevant scanning instrument with the card to complete the payment

it should be noted that as digital currency is a new way of payment, it has not been fully promoted. At present, it is only a pilot project in some cities. Last year, Shenzhen, Suzhou, Cheng and xiong'an new area all launched corresponding pilot projects. This year, Shanghai and Beijing also started digital RMB pilot projects. It is understood that today, the total transaction volume of digital RMB has exceeded 1.1 billion

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system

6. It will replace many instries. The emergence of an instry will certainly drive the reform of an instry

7. In theory, the block chain will make Alipay unemployed, but in fact, it is very difficult to work out and the government will not allow it. Br />7 month in the financial science and technology summit summit (LendIt), dot fusion chief executive officer, LendingClub co-founder Soul Htite (Su Haide) put forward "block chain will let Alipay unemployed."
is this too alarmist for Ali? Maybe it's not groundless
soul believes that blockchain has a subversive effect on the payment instry. With blockchain, the cash flow between people directly through the bank, rather than through a third party. If banks use block chains, what Alipay and WeChat pay will be useless.
"blockchain" is a series of data blocks generated by using cryptographic methods. Each data block contains the information of all network transactions in the past ten minutes, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. It all comes from the underlying technology supporting these cryptocurrency protocols. Puyin, a tea based digital currency, takes advantage of this feature of blockchain.

8. Blockchain is the underlying technology of bitcoin. You can think of blockchain as a distributed database for storing bitcoin transactions. In the whole network, each node will have a complete blockchain

blockchain technology has realized the key characteristics of tamper proof, decentralization, anonymity, security and reliability. Now more and more instries choose to use blockchain technology. For example, NASDAQ has adopted blockchain technology to realize LINQ, a private equity trading platform. It is more secure, and the transactions stored in the blockchain can not be tampered with, that is to say, once written, it is impossible to be modified. In the future, the application of blockchain will be very wide, and all aspects can be applied to blockchain technology. For example, in the future, schools can store the electronic version of Graation Certificate in the blockchain, which will not be tampered with. Employers can check the authenticity of students' graation certificate by querying the information in the blockchain.

9. There is no substitute. At present, it is more icing on the cake. In the future, it may be a basic framework and a core operation. For example, the application platform of SMIC blockchain public service platform in Changsha is a good example. Internet technology is the support of the underlying framework, and blockchain technology is the core of the platform.
