Huawei lays out digital currency
as far as I know, there is a big difference between the use of digital currency and traditional paper currency. The purpose is the same, but the technology, security and application are different. The simplest difference is that one is printed on paper, and the other is printed on the blockchain information system in digital form 
there are two simple understandings: currency digital currency is in the form of e-wallet, and RMB is paper currency. When it is used, one is to exchange currency and goods directly, and the other is to use digital currency wallet for transaction and transfer. Digital currency is certainly more convenient, while paper currency will have many problems, such as ring the epidemic, We should try our best to rece the risk of paper money transaction
when ordinary people don't understand the relationship between bitcoin and them, technical experts and financial experts have been arguing about the value of bitcoin and the advantages of digital cryptocurrency over existing payment systems. But none of this is important for understanding bitcoin
the only thing you need to know is that bitcoin is just another form of money, that's all.
Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance"
based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects. Bitcoin is a form of blockchain

to mine bitcoin, you can download special bitcoin computing tools, register various cooperative websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost<

blockchain is a technology, based on which there are many applications.
bitcoin is one of the most popular and well-known applications.
Second, what is the essence of blockchain technology
blockchain is essentially a decentralized distributed ledger database. Does it sound like a trap? Don't worry, we will explain it in the most profound and simple way. Anyone can check the public ledger, but there is no single user who can control it. Participants in the blockchain system will jointly maintain the updating of the ledger: it can only be modified according to strict rules and consensus, which has a very subtle design behind it.
at this stage, you are cleaning up the illegal and cheating accounts. If you exit, you will dect the money you g in one cycle. Exit cautiously
if there is no response, you can restart the phone, switch to 4G and try again. After logging in to other mobile phones, the previous account will be forced offline.
There is a long bridge on the beach of the tower at the bottom. You can walk to the central island and get to the second island through the central island
radiation island is an open survival game with nuclear theme, which focuses on nuclear energy again. Nuclear energy is an alternative new energy, but the panic caused by nuclear leakage is still difficult to eliminate. The game takes the distant future world as the background, the human hands have destroyed the beautiful home personally, the earth has become critical, the radiation is rampant, the weather is bad, what's more terrible is, fierce mutant zombies are everywhere, and the important task of the players is to survive in such an extreme environment
Introction:
primary Survival Guide: if you want to survive, food is essential. It is very important to get food in the 4399 radiation island game. All kinds of food and props will be randomly brushed on the map, which we can collect. It is very important in the case of lack of resources in the early stage. Of course, we can hunt animals to get food. In the early stage of survival, we can create two essential necessities in the game, furnace and bonfire, through simple operation
bonfires can be used for lighting and heating at night (it is worth noting that in the night mode, when the temperature drops, we will be fatally injured, so a bonfire is necessary. Of course, if conditions permit, sleeping directly can help you spend the night safely and quickly. In the 4399 radiation island game, the furnace can be said to be the most important thing to survive. We can refine various materials and cook in the furnace (how to use the furnace: click the furnace to enter the refining interface, and the two spaces above are the place where the articles are put in. Just put in the raw materials and fuel wood that need to be refined, and the successful refining items can be taken out in the space below)
primary survival suggestions: stone axe, stone pick, bow and arrow. In the early stage of 4399 radiation island game, stone axes and stone pickaxes can be made with very few resources. They can be used as acquisition necessities and weapons at the same time. Of course, we can also obtain resources through one handed tree rolling (this is also a small unexpected setting). Bows and arrows can also be completely obtained by simply collecting materials. You can look at the introction of manufacturing formula materials
