Digital currency mobile phone has no power
digital currency transactions only use the network, which has nothing to do with NFC. Of course, it can be used.
Digital currency carrier is digital currency wallet
digital currency is an alternative to paper money
functions and properties are exactly the same as banknotes, but the form is digital
Therefore, it can be seen that the use of digital currency will be more secure In addition, digital currency has unique coding, and there is no way to forge itand whose wallet digital currency enters may generate traceable information codes, including the identity information of the wallet owner. In this way, as long as the digital currency is spent or transferred, it is very easy to trace
even in the future, if big data and Internet of things technology are further upgraded, where you spend digital currency may be traceable, including spending a few yuan and so on, which can be easily known and traceable
in this case, your mobile phone is lost. On the one hand, it is difficult for the person who finds it to crack many passwords on the mobile phone. If the person who finds it takes a lot of effort to break the password, then if he wants to spend money or transfer money, it is also traceable
Digital currency is not attached to the memory of the mobile phone. If the mobile phone is broken, the digital currency wallet will not be lost. You only need to log in the currency wallet account on other devices to retrieve the corresponding digital currency
digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects:
1. Due to some open algorithms, digital currency has no issuing subject, so no one or organization can control its issuing
Because the number of algorithm solutions is determined, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency3. Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough
extended data
the central bank concted internal test on digital currency, and some civil servants received part of the salary paid in the form of digital currency
the screenshots of the digital currency wallet applications launched by Agricultural Bank of China, China Construction Bank and Bank of China are widely spread on the Internet, showing that they have many functions, including allowing depositors to track the transactions of digital currency and associate the digital currency wallet with their existing bank accounts

to understand decentralization is to understand blockchain. A real blockchain project is to practice the concept of decentralization through reasonable game rule design supplemented by information technology. Bitcoin system is an excellent demonstration project of decentralization concept and blockchain technology. It's no exaggeration to say that I think this is a revolution in the concept of the Internet and another revolution in the equalization of human beings. The last time it broke the inequality in status between people, this time it broke the inequality in the rules of the game itself. Because of this, blockchain can stimulate people's enthusiasm. It is a new thing that sounds like it can overturn all the old rules
why is it called "blockchain"
because Nakamoto designed this account book as a long chain of "packets", each "packet" is called a "block", and each of these blocks has a unique number (in the bitcoin system, the number is called height), which is the natural number 1, 2, 3, 4... All the way down, Jumping, interruption and repetition are not allowed<
the specific rules of blocks are explained below:
the first block was created by the inventor of blockchain "Nakamoto Tsung" personally. On January 4, 2009, Beijing time, on a small server in Helsinki, Finland, the first block was born, which is also called "Genesis block". On this block, the main information is:
the middle paragraph is a memorial of "Nakamoto Tsung" engraved on the first block. Starting from the second block, every block must be created in strict accordance with the rules of bitcoin system. The rules of the block are:
block rules
all the mysteries of the blockchain lie in the random number added to the tail, because it is so mysterious that ordinary people can only enjoy it, so I will call it "Olympiad" later for the convenience of explanation
because there are only two possibilities for each bit of a binary number, 0 or 1, the possibility of making up an Olympic number is one 72nd power of 2, that is, 1 / 4722366482869645213696. That's a dazzling number. It's about 1 in 4.7 trillion. In other words, it takes an average of 4.7 trillion Sha calculations to get an "Olympian number". You can see the value of each "Olympian number"
it may become a New Mathematical Olympiad with no rules to follow.
As we all know, China has begun to prepare digital RMB in recent years. In Shenzhen, some experiments and practices have begun. The so-called digital RMB is to transfer the real printed money into the form of digital characters. Although these currencies are issued in digital form, they have legal effect, because they are issued by the people's Bank of China. In other words, a dollar of digital currency has the effect of a dollar. The issue of digital currency not only greatly speeds up the process of digitization and scientization in China, but also has a certain role in environmental protection. We should know that the banknotes issued every year will consume a lot of trees and paper, and some banknotes can not be used again after they are damaged. In fact, it is a waste of paper, which is not environmental protection. The digital people's currency perfectly avoids these shortcomings, which is also one of the manifestations of human scientific progress{ RRRRR}
refers to your digital currency, which is put in the digital currency wallet of other people's mobile phones
or an exchange app on someone else's mobile phone
is it transferred or used for other transactions
your question is not clear enough. It is suggested to explain the actual situation again
