Digital money center

1. The core difference between centralization and decentralization is whether the private key is in the hands of the user. The decentralized platform can protect the user, such as celletf (celletf. IO), which solves the security problem of the user's assets, but the operation is relatively simple.

2. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis

above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized

3. Some with foreign qualifications will be better, safe and reassuring. At present, there are few in China. Most of them are done in Hong Kong on foreign platforms. You can ask the customer service for more information

4. It should be reliable.

5. That is, no one can control, not be controlled by the living center of a living group. Therefore, it can not be used as legal tender recognized by the state. There are a group of money speculators who argue that virtual currency will replace paper money every day. It's all bullshit. We must pay attention to investment risks. Now there are many pyramid schemes with virtual digital currency gimmicks to cheat money

The digital currency developed by the central bank has such a definition: encrypted digital string representing specific amount guaranteed and signed by the central bank . In a broad sense, digital currency includes a wide range of aspects, including electronic currency, virtual currency and legal digital currency. But strictly speaking, the digital currency developed by the central bank refers to legal digital currency

electronic currency is the digitalization of legal tender, including our common bank cards, Internet banking, electronic cash, Alipay and so on. No matter what the form of these electronic money is and through which institutions it circulates, its original source is the legal money issued by the central bank

In contrast, virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. For example, Tencent Q coin and other game coins, such virtual currency is mainly limited to circulation in a specific virtual environment; bitcoin, for example, solves the problem of decentralization and distrust through blockchain technology, realizes global circulation, and is sought after all over the world. In other words, virtual currency can only be closed in the network circulation, and digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency, bitcoin is illegal

the digital currency researched and issued by the central bank is indexed RMB, which belongs to legal encrypted digital currency from the perspective of national schemes, and it is not only a payment tool but also a currency itself< the purpose of digital currency issued by the central bank is to replace physical cash, rece the cost of traditional paper currency issuance and circulation, and improve the convenience and transparency of economic transactions

hope to adopt

7. At present, central banks and financial institutions all over the world are concting research on currency digitization and related technologies. At the "fintech summit in Shenzhen, China" hosted by Shenzhen Municipal Government on December 20, more than 40 units, including Ping An Group, Weizhong bank and Dacheng Fund, announced that they would jointly initiate the preparation for the establishment of China's Shenzhen fintech digital currency alliance, and cooperate with the central bank and other financial regulatory departments to study and formulate digital currency instry standards and relevant institutional mechanisms<

with the development of Internet technology and the profound changes of global payment methods, digital currency with higher operation efficiency and stronger economic adaptability is becoming a new trend of currency development in the future
in this trend, central banks and financial institutions around the world are concting research on currency digitization and related technologies. At the "fintech summit in Shenzhen, China" hosted by Shenzhen Municipal Government on December 20, more than 40 units, including Ping An Group, Weizhong bank and Dacheng Fund, announced that they would jointly initiate the preparation for the establishment of China's Shenzhen fintech digital currency alliance, and cooperate with the central bank and other financial regulatory departments to study and formulate digital currency instry standards and relevant institutional mechanisms
currency digitization is the general trend
in a global science and technology innovation survey released by KPMG, digital currency, 3D printing, Internet of things and biotechnology are listed as the most promising technologies in the next three years. At present, many countries in the world are promoting the research of currency digitization
at the beginning of this year, the Bank of England announced a new research report that the combination of digital currency and mobile technology may completely change the shopping habits of British people, and the Bank of England is considering using this technology to release official digital currency. Sweden's central bank is considering issuing its own digital currency, ekrona, in response to a sharp decline in the country's cash use

in 2014, the Central Bank of China set up a special research group to demonstrate the feasibility of issuing legal digital currency. At the beginning of this year, the central bank held a seminar on digital currency to further clarify the strategic objectives of the central bank in issuing digital currency. In November, the 2017 annual personnel recruitment plan of the printing Science Research Institute, a unit directly under the central bank's official website, showed that six professionals with master's or doctor's degrees would be recruited for digital currency research and development< In an interview with the media a few days ago, Yao / > deputy director of the science and Technology Department of the central bank and head of the preparatory group of the digital currency Research Institute, said that the prototype scheme for the central bank to issue legal digital currency has completed two rounds of revision, and is expected to be tested in relatively closed application scenarios such as the bill market in the future, but there is no clear timetable for the launch of legal digital currency in China<
Third Party Payment institutions may disappear
at the first "China Shenzhen fintech (Financial Technology) summit" held on December 20, the reporter of daily economic news learned that, under the guidance of Shenzhen municipal government, Ping An Group, China Merchants Bank, Weizhong bank More than 40 units, including Dacheng Fund, will jointly initiate the preparation for the establishment of China's Shenzhen fintech digital currency union and fintech Research Institute
according to Yao Yudong, chief economist of Dacheng Fund, the alliance will cooperate with the central bank and other financial regulatory departments to study and formulate the digital currency instry standards and mechanisms. The Research Institute will comprehensively carry out the research on fintech infrastructure and innovative business, and explore and promote the application of big data, cloud computing, artificial intelligence blockchain and other technologies
as one of the sponsors of the alliance, Li Lin, founder and chairman of fire coin, pointed out that when it comes to digital currency, it should be made clear that there is an essential difference between the digitization of legal currency and digital currency. The essence of encrypted digital currency represented by bitcoin is a standardized digital asset. However, because the digitization of legal currency may choose to use the underlying technology of encrypted digital currency blockchain as one of the core implementation technologies, there is a close relationship between the two
Li Lin said that blockchain has outstanding technical advantages in security attributes such as non repeatable transaction, non forgery and non tampering. Digital currency represented by bitcoin has the characteristics of disintermediation, openness, transparency and traceability, which will have a profound impact on the future circulation of sovereign digital currency
"in the global cryptocurrency operation and circulation system, there is a unified and open protocol, and different institutions follow the standard protocol, which provides the basis for the cross platform circulation of currency accounts. There is no need for third-party payment companies to provide services to connect with different banks. " Li Lin gave an example. In his view, in the future, if the sovereign digital currency uses the unified and open blockchain agreement or other agreements, and only provides technical services of cross bank agreement, the third-party payment company will disappear
at the same time, Li Lin pointed out that the structural system of encrypted digital currency under the decentralized structure has brought great problems to government supervision, so there will be some changes in the sovereign digital currency system. For example, anonymity is controllable anonymity, unlike complete anonymity in the bitcoin network.

8. In mobile applications, the introction of general digital currency will come with a digital wallet, and then use it in the digital wallet.
