1. The concept range is different. bitcoin is a kind of digital currency, and the concept of digital currency covers bitcoin

However, some digital currencies have independent issuers

The biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

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. Bitcoin is a digital currency

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 currencies, such as bitcoin, lettercoin and ppcoin, are electronic currencies created, issued and circulated by means of 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

not long ago, the people's Bank of China and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, which clearly regulated the relevant behaviors. Experts pointed out that "virtual currency" is not legal tender (legal currency) issued by monetary authorities, but a specific virtual commodity in essence

therefore, it is undoubtedly a great legal and economic risk to think that "virtual currency" has or will have the nature of legal tender and to carry out speculation, network fund-raising, lending and financing

8. 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

9. The TOBI platform won't do that. This is a regular platform. It won't happen. It's going to pay soon.

10. Bitcoin is a controversial thing, and the controversy between the devil and the angel, there is no "between", which becomes a bit incredible.
