How about the decentralized digital currency Hubble

1. 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

2. 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

3. HNB community set up a GMH, the policy and decision were voted by decentralized participants, executed by smart contract, without human intervention. Major issues shall be discussed and voted by the general meeting of all community members. The full-time boards (development board, reserve board and arbitration board) authorized by GMH perform their respective ties. It effectively protects the rights and interests of all.

Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

in recent years, the excessive issuance of banknotes has led to the aggravation of inflation, the frequent security crisis of third-party payment, and the graal maturity of blockchain technology, so decentralized digital currencies such as bitcoin, Ethereum and reborn have emerged. Digital currency has the advantages of low transaction cost, fast transaction speed, high anonymity and fixed amount of money

At the same time, the use scenarios of digital currency become more and more abundant, which makes the user acceptance grow. At present, the use of digital currency has covered all kinds of scenes, such as shopping consumption, wage payment, transportation, travel, takeout settlement and tuition payment. The expanding landing scene has also brought a wider range of consumers. In general, although the number of users of digital currency still accounts for a small proportion of the total population, the number of users is growing. At present, the utilization rate of digital currency has exceeded 10% in 10 countries around the world

In June 2019, Facebook launched Libra virtual cryptocurrency, which has caused worldwide influence. The emergence of Libra may form a global super sovereign currency, thus affecting the traditional transaction settlement currency. For China, the emergence of Libra, on the one hand, will have an impact on China's traditional currency and threaten the sovereign status of China's currency; On the other hand, because RMB is not included in Libra's basket of currencies, it will rece the reserve demand of RMB by central banks, thus hindering the internationalization of RMB. In response to this threat, CCTV timely launched the central bank digital currency. In September 2019, according to China Daily, the central bank's digital currency closed-loop test has begun, and the central bank's digital currency is about to come out

coincidentally, in addition to China, central banks around the world have also announced that they will launch a centralized digital currency based on national credit. In 2015, Ecuador took the lead in launching the national version of digital currency, which can not only rece the issuance cost and increase the convenience, but also enable people in remote areas who cannot have banking resources to obtain financial services through the digital platform. At present, Canada, Brazil, Norway, the United Kingdom and other countries are studying the central bank legal digital currency, while the Bahamas, Sweden, Russia and other countries are discussing the possibility of digital currency issuance. Generally speaking, the developing countries which have received a great impact on digital currency have supported legal digital currency for financial inclusion, breaking through sanctions and other reasons
