1. Take bus NO.48 at Dongfeng overpass or Taixing South Road and get off at decaili. Go ahead to Balitai overpass and turn left. Inside Jingyan building is Balitai new culture square

or you can walk to Jintang Road, take bus no.643 at Hedong stadium and get off at Balitai (Weijin Road). Go ahead and cross the overpass to Jingyan building

2. How to mine every day; Share mining tips every day; When the initial physical strength is tight, when it is close to 20 times, you can leave two small monsters without fighting. For example, when the number of monsters reaches 18, you can leave two small monsters, and then dig long-time gems to save your strength. When the physical strength is close to the upper limit, you can kill the two small monsters and start looking for the big boss. This can avoid that you can't find the big boss if you don't have enough medicine. Because mining is mainly for the soul crystal and the golden man, the little monster will appear in your field of vision, and the little golden man will appear in your field of vision + 1, so the larger the field of vision you open, the greater the chance of the appearance of the little monster and the little golden man. The same physical strength, in order to open a larger field of vision, the following mining method is recommended. First, one line is g to the bottom. At present, the deepest mining area is 302, which can be g to about 270. Then, four lines are opened horizontally, which are A copper tin Ruby line, about 30 deep A line of iron violet, about 65 deep Silver Emerald is a line, and other gem ores are a line at 270 depth It doesn't matter about the left and right sides. You need to dig horizontally and don't dig back. You can adjust up and down if you need minerals or rocks that need explosives. This can ensure the maximum range of vision under the same physical strength. When you need certain resources, you can dig along a certain line. In addition, if the field of vision is large, more pink gemstones such as pink diamonds will be proced, which can improve the mining efficiency. It is suggested that novices can open a miner card after digging to the depth of 270. For nothing else, the efficiency of double line mining can be improved a lot. There is no need to upgrade the types of automatic mining, because it does not improve the efficiency of mining. If there is a shortage of ore, you can buy more miners. You must order titanium Titan steel before going to bed every day. Automatic miners are the same as mining areas. Although they can't be used at present, they can't be used in the later stage. Keep at least 4 or 5 explosives, otherwise sometimes you will cry when you meet the little golden man surrounded by stones.

1. During the first phase of the interstellar war, players only need to place the hang up location in the first and second levels of each map, and they will get a crystal ore as well as props. Because the first and second levels can get props once an hour, So players can get 24 crystal ores in one day, and 24 * 7168 crystal ores in seven days

2. During the activity period, players only need to open any treasure box in the mining area to a certain extent to get the crystal ore reward, which is divided into five grades

3. Electronic competition Wallet: ring the activity period, you can get rewards when you recharge to a certain amount, among which you can get crystal ore bag when you recharge more than 30 yuan, and you can get 100 crystal ore when you open the crystal ore bag

accumulatively support 50 crystal ores to obtain: honor fragment * 1000, detonator * 5, troll statue * 5, mysterious stone * 1

4. If you want to contribute to the bitcoin network, it's a good choice to run a full node to synchronize the block data; If you just want to use bitcoin, you don't need a full node wallet at all. You just need to install a new wallet. The better one in China is the coin pack.

5. It means that your wallet is consistent with all the blockchains on the Internet. It takes a long time for bitcoin wallet to synchronize and takes up a lot of hard disk

6. Bitcoin wallet has a large amount of data, many areas and dozens of G's. If it's the first synchronization, it's normal.

7. Only full node clients like bitcoin core need longer synchronization time. Technically, synchronization is a process of downloading and verifying all previous bitcoin transactions on the network. Some bitcoin clients need to know all previous transactions to calculate the available balance of your bitcoin wallet and complete new transactions. This step consumes a lot of resources and needs enough bandwidth and space to store the whole block chain. In order to maintain the security of bitcoin, enough users need to use the full node client, because they play the role of confirmation and relay transactions
an error has occurred, which may be e to network disconnection or incompatibility. Just update it. As a matter of fact, the online money and packet technology has developed quite mature now. It's better to put bitcoin in your own computer than in your online wallet. Of course, if you are a technology flow, you can go anywhere.

8. In order to achieve the goal of decentralization, everyone in bitcoin network can keep accounts. But with so many people all over the world recording accounts at the same time, who should listen to
this is the consensus issue of bitcoin. In other words, how to achieve decentralization at the same time, let the nodes of the whole network reach a consensus and keep the consistency of all accounts? This is a problem that the decentralized system could not solve for a long time in the past
Nakamoto Tsung proposed the solution of proof of work. It stipulates that the person who pays the most calculation work has a better chance to obtain the final bookkeeping right. His bookkeeping results will be recognized by the whole network. How to measure the calculation workload? Bookkeepers need to spend computer power to solve a problem called hash function. This problem can only be guessed one by one through computer enumeration. The stronger the calculation power, the easier it is to guess the right answer. Once a lucky bookkeeper finds the answer, he will get the right to keep accounts. And get a bitcoin reward. Everyone should listen to his accounting results and start new records on his basis
to put it simply, more is more. The harder you work, the luckier you are. POW solves the problem of mutual distrust nodes reaching consensus, and is considered to be the ancestor of all consensus mechanisms. It makes bitcoin a truly decentralized autonomous system.

9. Single precision decimal point can be accurate to 7 decimal places. Double precision can be accurate to 15 decimal places. They are all floating point numbers. This is the biggest difference between them. It must not be confused.
