digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes

based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds

Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases

3. For many people, the concept of digital currency is a mystery. But there is no doubt that digital currency is different from virtual currency

virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency

in 2013, the central bank, together with five ministries and commissions, issued the notice on preventing the risk of bitcoin, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, not in the form of currency and legal currency< At the same time, digital currency is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.

5. The Chinese meaning of utxo is called: no cost transaction output
utxo is an account model in digital currency, which is different from our current bank account model< Taking transfer as an example, the current situation is:
I want to transfer 2000 yuan to Yiyi. I want to transfer 5000 yuan to her from my China Merchants Bank card. After transferring 2000 yuan to her, 2000 yuan will be dected from my China Merchants Bank account and 3000 yuan will be left
if it's utxo based on bitcoin, the situation is like this:
I have 5000 bitcoin, I transfer 2000 bitcoin to Yiyi, and 2000 bitcoin is consumed, right? be careful! This 2000 is not dected from my 5000 total. Instead, my total bitcoin will be divided into two parts (one is
2000, and the other is 3000). This is called "generating two new utxos": Yiyi takes 2000 bitcoin, and I take 3000 bitcoin myself. 3000 is my change
after the successful transfer, the 2000 bitcoin I gave Yiyi has been used and consumed, so it can no longer be called utxo. However, the 3000 bitcoin I gave my change has not been used yet, so it can also be called utxo, that is, the transaction output that has not been spent. Then, if I have 5000 bitcoins in total and I transfer them all to Yiyi, I just need to generate a new
utxo to Yiyi, and there is no need to change it
based on utxo, every transaction should confirm the situation before bitcoin and check whether bitcoin exists in my utxo. If not, the system will reject your transaction
in this way, the input and output of each transaction are related, which can be traced back to the birth of bitcoin, that is, the source of mining, through utxo
If I want to send the same utxo to two people, the system will only confirm the first one received. Once it is confirmed that utxo has been consumed, you can not transfer it to the next person, thus avoiding the problem of double payment
since the system only confirms the one received first, the problem arises. How does the system know who is first and who is second? Of course, the system knows, because the system has something called "time stamp".
