Why do virtual currencies need consensus

1.

virtual currency is valuable because of its liquidity and not easy to query

a bitcoin system written by a pile of codes, from worthless to 100000 yuan, what is bitcoin? Why is it so valuable? Once you understand the nature of bitcoin, you won't just focus on currency price fluctuations. It can be said that the invention of bitcoin has given people unlimited imagination. Of course, the value of bitcoin is also determined by its demand. So who needs bitcoin in the first place? When we talk about how to reach a consensus on a broader level, let's first look at the essence of value. Why is gold valuable and what is its essence

in my opinion, a group of virtual currencies led by bitcoin will exist for a long time and will not replace the current legal tender. It will exist independent of fiat money and will not belong to any country. Some virtual currencies are recognized by some people first, and then graally form a wider circulation because of their value. More people reach this consensus, and finally they have the value of existence. Of course, most virtual currencies have no value and are aviation currencies. If a currency wants to exist for a long time, it must go through a long period of ups and downs, and constantly dig out its greater use value, in order to become a virtual currency with real value

2. You are right. Indeed, it will be rolled back. If the transaction is unfortunately packaged on the fork, the transaction is likely to be cancelled after the main chain is synchronized

the reason why we need six confirmations is that it is more difficult to obtain the optimal solution (to prevent single node fraud). One block may also be able to get an optimal solution, and it is basically impossible to get six blocks together. It has nothing to do with bifurcation

3. It has been a consensus that digital currency is a kind of currency, which can be paid and protected. Bitcoin is also known as digital gold
you don't need to understand, just know that it's the truth, and it's more and more valuable

4.

Often when we talk about value, we will naturally relate to price. Indeed, price is an important data to measure value. As a blockchain technology, bitcoin's price reached 140000 RMB when it was high, and now it has dropped by about 50%, but it is still as high as 80000 RMB

At this point, you may have understood: if people do not have a common understanding of a thing, and do not give value to a thing, many things will not become "valuable". Just like our understanding of air and food, it is necessary for us to live and survive! This is the "consensus". We all believe that if we want to live, these two are indispensable! Therefore, we can conclude that the essence of value is consensus. What is the value consensus of virtual currency? Most people think that the essence of currency is not consensus, but the credibility and authority of the ruling government. This is not unreasonable. The government can only be one of the sources of value consensus, so most people think it is not comprehensive. In today's society, our consensus on the value of things comes from many ways, such as: Endorsement of authoritative institutions, corporate credit, religious belief, support of scientific theory

5. Facebook employees are already using Libra coins, and if a member of Calibra team (Facebook's digital wallet project team) is late for a meeting, he will be punished by confiscating a certain amount of virtual currency.

Bitcoin was born on January 3, 2009, which has a history of 10 years. The value of bitcoin has soared from zero to US $19850, the highest point in 2017. And most people have been concerned about cryptocurrency and bitcoin since then. Before that, most people would think that bitcoin was just an "internet currency", similar to q-coin

bitcoin is the leading cryptocurrency, which has been the absolute consensus in this instry. Looking back over the past few years, among the top ten cryptocurrencies in terms of market value, only bitcoin has always been the first, and the remaining counterfeit currencies are all in the past

7. I feel that virtual currency is a progress across the times, reflecting people's creative thinking.

8. Regulators talk about the supervision of virtual currency again. Why should virtual currency be supervised< p> Recently, the regulatory authorities reiterated their views on virtual currency, and then strengthened the supervision of virtual currency. This argument has attracted a lot of people's attention on the Internet. For a long time, virtual currency has been repeatedly banned on the Internet, which has caused many governments to have a headache. For example, bitcoin, which has been popular on the Internet before, has been admired by many people, and many people spend their time on it; Mining & quot; In recent years, the infatuation for bitcoin has reached a fanatical level. Recently, I believe many people have heard of dogcoin. As a similar proct of blockchain, dogcoin is a kind of virtual currency like bitcoin, which has set off a huge wave for people's social life

In addition, virtual currency has led many people to inlge in it and reced their enthusiasm for life. Therefore, many people waste their time and it is very unwise to waste their time in this kind of virtual data. Therefore, we should spontaneously boycott the virtual currency and contribute to the maintenance of the world monetary system

9. There is no such assumption. Foreign countries are not against cashless society. They just don't have talents in this field.
