2. What is the double flower problem

< / UL >

the problem of double spending is that a sum of money can be spent twice, three times and many times. Why has the double flower problem become such an important issue in the bitcoin system

the reason is that bitcoin is a virtual currency. It is virtual, presented in the form of code, and can be copied. Once the code vulnerability is broken, the same bitcoin can be recycled. In this way, the "money" of bitcoin will become very weak

let's think about it. If a sum of money can be spent many times, and you have 500 yuan, you can buy a 500 yuan dress, which can be recycled, and then buy a pair of 500 yuan shoes. In this way, can money be called money

therefore, when Nakamoto set up the bitcoin system, all his technical means are basically around solving the "double flower problem" of

, to protect bitcoin as a kind of currency, its own function as a means of payment

in fact, the problem of double spending is not a problem in our present centralized world, because with banks, the settlement of money transactions is through banks, which is very safe. If you have problems, you can go to the bank directly

however, in the decentralized world, without such a central institution as banks, it is necessary to ensure that a sum of money can only be spent once. How to eliminate the "double spending problem" under the premise of decentralization is a difficult problem

let's just say, why is Nakamoto so persistent in pursuing "decentralization" and asking for trouble? No, he hopes to solve some social problems through decentralization, the most important of which is the inflation caused by the excessive issuance of money by the authority

so, let's sum up his logic: centralized currency issuance leads to inflation - so we need to achieve Decentralization - decentralization will face many problems, the biggest problem is the double flower problem - so we need to solve the double flower problem - how to solve the double flower problem

here, Nakamoto introces the concepts of utxo and "timestamp" to solve the double flower problem

5. It's not the same thing, but it's all virtual money. Bitcoin rose from a dozen dollars to 1200 dollars, and then fell to about 600 dollars, which is the reason for speculation. Many countries do not recognize it as a legal currency, because the risk is really great. Bitcoin trading platforms in the United States are frequently attacked by hackers, resulting in investors' inability to trade normally, and there is no clear regulation and law. So if you don't understand it, you'd better know more about it first. Tianhou has a lot of bitcoin related news, which I read from there, You can have a look if you're OK.
