Technical theory of digital currency

1. digital currency is the proct of currency development to a certain stage. The issuance of digital currency is mainly to make transportation more convenient and also concive to the supervision of the economy.

2.

From 2015 to 2017, the price of bitcoin increased from more than $100 to $17000, a 100 fold increase. Today, the market value of various numerical currencies is more than 700 billion US dollars. The myth of their benefits is not nonsense

but there are many things behind the chaotic digital currency. You may ask why air currency can be listed on the stock exchange? It's very simple. The exchange also has to charge a part of the fee. Raise the price and then sell it to make money. So the question is, how to identify air currency

first of all, you need to look at the projects behind the digital currency and see what their team background is. Generally speaking, teams without experience in the instry tend to earn money, but how much experience do they have? It is better to be able to participate in the construction of Ethereum and bitstock communities. Such a team is often more reliable. This requires investors to have a certain screening ability to identify good or bad

secondly, there is no way to implement many projects. How can we identify them? In addition to the ability of the team, we also need to see the feasibility, which requires us to systematically learn the knowledge of bitcoin and blockchain. For example, Zhu Jiawei, the COO of fire coin network, learned the blockchain from 0 to 1, and clearly described the development process of bitcoin and blockchain in the form of audio and text. Besides, don Tapscott and Alex Tapscott's "blockchain revolution" are worthy of careful taste

moreover, the bubble of digital money is very large nowadays. In the bubble, it is not difficult to make money, but the key is not to be greedy. Long term holding is not good, but it can be operated in a short term. You can make money if you want. However, the key is that people are all profit-making and greed is their nature. Therefore, many people do not accept what they see. They originally made money, but later they lost everything. The gain is not worth the loss. Therefore, it is necessary to control greed

3. Blockchain technology is the basic technology to construct digital currency. From bitcoin blockchain to Ethereum and super ledger, blockchain technology is still in the process of continuous development and improvement, which needs to be based on the actual needs of the central bank's digital currency. At present, Guido team has developed a digital currency technology theory and construction method suitable for China.

4. The future world will be a digital world, and money will develop from paper money in the past to digital money in the future, which is a trend. Because in order to adapt to the digital world, the future currency must also be digital. It can be predicted that digital currency will be safer, faster and more convenient in the future. Now many blockchain technology procts, although its name is what currency, but in fact it is not currency. Under the guise of digital currency investment, it is a Ponzi scheme. Even some of them don't even have blockchain technology, which is just a fake number to cheat people.

5. I'm too young to remember the birth of the Internet. When the Internet was booming, I was in high school, a little confused about what happened. At a family party, when my cousin bragged about how much money he made from buying and selling domain names, I thought it was stupid
it's not a reality. Up to now, I still think it's stupid to make money by buying and selling domain names. I know it happens sometimes. It's like a high-risk, low return investment
as a result, the Internet did. Now, 20 years on, domain names are cheap, and search engines make them brand specific Note: the author means that the convenience of search engines makes domain names cheaper and cheaper. Domain names are only related to brands.)
What does this have to do with the value of bitcoin
this is an example of how people's views on value change with the development of technology
at this point, most people see bitcoin as money. The chairman of the US SEC said, "yes, that's how drug gangs use it. Everyone I know thinks so.". It's called "bit coin" for a reason
bitcoin maximalists call it hard currency, critics call it fake money, and veteran players call it cyber currency

Digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency

Compared with paper money, digital money has obvious advantages, which can not only save the cost of issuance and circulation, but also improve the efficiency of transaction or investment, and enhance the convenience and transparency of economic transaction activities. The issue of digital currency by the central bank also ensures the continuity of financial policy and the integrity of monetary policy, and also ensures the security of monetary transactions

although the issuing method of digital currency is still under study, paper currency has been regarded as "the currency of the previous generation" by some professionals, and it is the general trend to be replaced by new technology and new procts. Due to China's large population and volume, the timetable for issuing digital currency is still uncertain. It is predicted that digital currency and cash will be in parallel and graally replaced for quite a long time. When the era of digital currency really comes, people will carry less and less cash, travel more and more safe, poverty alleviation more and more accurate, corruption more and more difficult to escape, and thieves more and more difficult

extended information:

in November 2016, the central bank prepared digital currency, and the cash is likely not to exist in ten years

in November 2016, China digital currency Research Institute was established to cultivate high-level talents of digital currency, carry out digital currency research, consultation, development planning and related activities. It is a non-profit unit with legal license approved by relevant ministries and commissions, and is committed to promoting the integrated development of scientific research and Practice of digital currency instry

so far, Hangzhou, Shenzhen and Guizhou have become the three hot areas for the central bank's digital currency pilot. It is reported that Hangzhou is actively promoting the planning and construction of Qiantang River financial harbor, including the blockchain instry. Hangzhou will build the first blockchain Instrial Park in China, which is located in the Internet Finance town of Xihu District, surrounded by ant financial services, e-commerce bank, Zhejiang University and its science and Technology Park and other well-known enterprises and parks

7. Blockchain and distributed ledger technology make digital currency development more reliable
blockchain technology has been questioned by the collapse of the centralized currency exchange, but its potential to solve the trust and centralization problems of the existing information architecture has attracted a lot of attention. Blockchain technology first gained great popularity in the field of bitcoin and digital currency. It uses a single shared ledger to store information. It is no longer to let a single central organization obtain the account book, but to obtain multiple copies of the same distributed account book by different nodes in the peer-to-peer network. Shenzhen yuanzhongrui blockchain technology adopts advanced encryption technology to ensure that any new information in the account book can not be tampered, unless it meets some preset parameters. Moreover, this kind of Ledger has stronger defense against external attacks, such as network attacks, because this decentralized system does not have a single point of failure with high cost of centralized information architecture. At the same time, all trusted nodes can affect any modification of the ledger, provided that they meet the specific preset parameters. These changes will be immediately reflected in the ledger, and all trusted nodes can obtain relevant data to make correct decisions. It can also adjust the design of the distributed ledger, create a hierarchical system within the architecture, and configure appropriate access rights and different levels of authority
blockchain and distributed ledger technology are concive to change the management mode of land registration. At present, the credibility of the real estate market is at the lowest level, which is attributed to the inefficient and opaque property registration system. The system relies on the centralized acquisition of land registration and corresponding property transaction information. Using distributed ledger technology to obtain, manage and modify these information can ensure that the public will not be infringed by land transaction fraud. Similarly, distributed ledger can simplify and integrate cross instry and cross regulatory compliance process, because it contains real-time compliance information needed by government departments, banks, investors and other third parties. By integrating data points of multiple projects and providing feedback on beneficiaries' project participation, we can better track the implementation of social welfare plans
at present, the biggest problems of technology development include: transformation cost of unique data storage system, data reliability verification of network nodes or all levels, privacy and security dimension of decentralized data acquisition, and revision of information technology act. What's important is that blockchain technology will change the way the government interacts with citizens, and this huge change is bound to be resisted by civil servants. These are all possible problems. We should take immediate action to formulate a regulatory framework to guide application development in addition to adopting blockchain technology.

8. Blockchain is its underlying application technology, and digital currency is its currency. Its practical application has little impact on the fluctuation of digital currency
when the economy is stable, it doesn't rise. When the economy is in turmoil, people begin to store digital currency. Of course, it is convenient for some corrupt elements
now the economy is stable, the digital currency is in a bear market, the financial crisis, the crisis, and only when there is a crisis can there be an opportunity. At that time, the rapid growth of bitcoin was the opportunity in the financial crisis. Don't worry, there will be a bull market in digital currency, which is expected to come in the second half of next year

9. In fact, the technical systems corresponding to various digital currencies are quite different
moreover, the development of digital currency is still immature.
