1. At present, bitcoin is the only reliable virtual currency. Bitcoin is a kind of virtual currency generated by the corresponding algorithm, which needs to use a large number of mining machines, that is, servers for mining. At present, only the virtual currency issued by the central bank is legal in our country, and the others are illegal
I hope I can help you. Thank you for your adoption.

2. As a blockchain researcher, many new people often ask this question. In fact, there are two main ways to invest in bitcoin. The first is to buy bitcoin directly from the corresponding digital currency exchange; The second is to mine for bitcoin
first of all, mining is the main way to obtain bitcoin, but the current threshold of mining is relatively high. If you choose to mine by yourself, first you need to understand certain technology, then download the bitcoin client and mine by yourself according to the online bitcoin mining tutorial
however, in theory, bitcoin can still be mined with computers or graphics cards. However, e to the development of mining instry in recent years, the whole network computing power of bitcoin is extremely terrible (more than supercomputers), so if you want to mine with computers or graphics cards, you can't find bitcoin, If you want to dig bitcoin, you still need to buy mining machines. Now the better mainstream mining machines in the market have to be tens of thousands. Of course, there are cheap second-hand mining machines, but these second-hand mining machines are all obsolete ones, and the electricity cost of mining is relatively high
in addition to the second way of direct purchase, the digital currency exchange is a special place for bitcoin trading. If you want to own a bitcoin, you can buy it directly with money. However, it should be noted that there are many digital currency exchanges in the market at present. Many small exchanges are specialized in cutting users and eating customer losses for a living. Therefore, when choosing an exchange, it is better to focus on the head exchange. For example, Hufu, one of the head exchanges in China, I have been using it for nearly two years, and it is very stable and safe.

3. In the first floor of the valley mine cave on the edge of viper Valley, we can see an NPC named shigongtou. As long as we click this NPC, we can enter the mine cave where we can dig. The deeper the mine cave, the higher the risk we will encounter, but the more abundant the relative rewards will become
we can go to the mine for half an hour every day through shigongtou. Although it's only a short half hour, it's the fastest way for novice players to earn Yuanbao. Because the difficulty of each level is different, players of level 35 or so can go to the third floor of the mine, while those of level 35 or below can go to the second floor of the mine, As for the first floor, because the shipment is too rubbish, we do not go mining
after entering the mine, we will find a large number of zombies around us. The level of zombies on the third floor is level 40. As long as our combat power is not too low, we can easily solve them. After that, we need to find a safe place to speed up mining. Here, new players choose the corner, where we are not easy to be found by other players, It's only 2 zombies that can be refreshed at most once around, which is very easy for us to solve
as long as we persist in mining for half an hour every day, we can purify at least 20 pieces of 5-quality black iron ore at the end of the day. According to the price in the game, we can get 60 yuan. For today's 50 equipment weaving, we only need to mine for two to three days to replace a set of 50 level equipment, As for weapons, we still have to work hard for a week to buy a powerful weapon.

4. It seems that it can't be refunded, because it's equivalent to spending a certain amount of gold ingot to obtain the qualification of mining. If you are lucky enough to mine in Wu you legend, there will be a lot of harvest~

6. We know the process of information computing hash packing: transaction record, time, account number, last hash value. We also know that all calculation and storage need to consume computer resources. In Nakamoto's design, the completion of bookkeeping can be rewarded with bitcoin by the system, which is also the process of issuing bitcoin. Therefore, bookkeeping becomes mining
bookkeeping
because bookkeeping is a reward, each time you can add a certain number of bitcoin for yourself, so everyone is competing for bookkeeping, which of course leads to a problem: when there is inconsistency in bookkeeping, the system introces workload proof to solve the problem, and the rules are as follows:
1. In a period of time, only one person can succeed in bookkeeping
2. Obtain the unique bookkeeping right by solving the cryptography problem
3. Other nodes the bookkeeping results
but before the workload proof, The accounting node will do the following preparatory work:
1. Collect the original transaction information that has not been recorded in the broadcast
2. Check whether the payment address in each transaction information has enough balance
3. Verify whether the transaction has the correct signature
4. Package and record the verified transaction information
5. Add a reward transaction: add 12.5 to your address Bitcoin
if you succeed in competing for bookkeeping rights, you can get a reward of 12.5 bitcoin
workload proof
the hash value of the previous block and the current account page information will be hashed together as the original information in each bookkeeping. In order to ensure that only one person can keep accounts around 10 minutes, we have to improve the difficulty of keeping accounts. The results of hash must start with several zeros. In order to satisfy the condition, hash is to introce a random number variable
denoted by pseudo code:
1. Hash (last hash value, transaction record set) = 456635bcd
2. Hash (last hash value, transaction record set, random number) = 0000afd635bcd
if you change part of the original information of hash, the hash value will also change continuously. Therefore, when you run hash, the value of random number will change continuously, A random number can always be found so that the result of hash starts with several zeros. The node that finds the random number first obtains the unique bookkeeping right
verification
after the node successfully finds the hash value, it will broadcast and package the block to the whole network immediately, and the node of the network will verify it after receiving the broadcast. If the verification is passed, it indicates that a node has successfully decrypted, it will not compete for the current block, but will choose to accept the block and record it in its own account book for the next round of competitive guessing. Only the fastest decrypted block in the network will be added to the ledger, and other nodes will to ensure the uniqueness of the whole ledger
If a node has cheating behavior, it will cause the node of the network to fail the verification, give up its packaged block directly, and cannot be recorded in the general ledger, then the consumption cost of the cheating node will be in vain. Therefore, miners consciously abide by the consensus protocol of bitcoin system, and ensure the security of the whole system
it's like you go to the construction site to move bricks. After moving bricks for one day, the contractor asks you how can you prove that you move bricks for one day?

We do it in Nanning. Is it the following
second hand ones are not easy to use, so it's better to make new ones
the length and width of the ore washer should be designed and matched according to the actual needs
at present, we design a new type of recer with a width of 1.9 to 2.0 meters, a diameter of 10 to 12 meters, a power of 55kW and a zq1000. Compared with the traditional 7.6m machine, it is more suitable for the raw ore with more mud, and the particle size is less than 200 mm, but it is better to be broken to less than 100 mm before ore washing. This new type of equipment can achieve the cleaning effect of two sets in series. For the raw ore with more mud, the hourly output is 50-100 tons
if you need a small one, you can also customize it
8. Mining is the most primitive "exploration method" to obtain digital currency. In essence, it is to solve a complex mathematical problem with computer. If blockchain is compared to a large account book, the block in which is a page in the account book, and all miners are bookkeepers, the process of mining is bookkeeping, and also to maintain the normal operation of the whole network
the process of mining is very simple. Take bitcoin as an example. Every 10 minutes, all the miners work out a math problem together. Whoever works out the answer first is equivalent to digging this block and getting the corresponding bitcoin as a reward. Mining equipment is the first to use computers. With the rising price of bitcoin, more and more people participate in mining. CPU mining has graally turned into a professional graphics card. In recent years, it has become a specific mining machine. This evolution is e to the problem of computing power. As I said just now, mining means "all miners work out a mathematical problem together." the higher the computing power, the stronger the hardware computing power and the faster the speed. Suppose that the computing power of the computer is 1, the computing power of the graphics card is 5, and the computing power of the mining machine is 100, then the mining efficiency of the mining machine is 100 times that of the computer, It's almost impossible for computers and mining machines to dig bitcoin together
warm tips: investment has risks, so we should be cautious in choosing. According to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have monetary attributes such as legal compensation and compulsion, is not a real currency, does not have the same legal status as currency, and cannot and should not be used as currency in the market, Citizens' investment and transaction of virtual currency are not protected by law
