In recent years, the rise of financial technology drives the digital and intelligent development of finance, and the form of money is also evolving. Recently, the news of digital currency has attracted people's attention, and there is still a lot of gap with the current online payment
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".
you can set this charge, which normally ranges from 0.0001 to 0.0005 each time. If you set it high, the bitcoin network will confirm quickly, if you set it low, the confirmation will be slow.
