1.
As of July 24, 2020, the state has not issued any laws to prove that bitcoin mining machine is illegal
bitcoin mining machine is one of the ways to obtain bitcoin. Bitcoin is a kind of network virtual currency proced by open source P2P software
it doesn't rely on the issuance of specific monetary institutions, and it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
extended data
the issue and transaction of bitcoin are realized by mining, and it is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block
the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins. In addition to the block award, the miner will receive a handling fee for all transactions within the block<

2. Bitcoin uses a graphics card to do an arithmetic, just like we do math problems. It has a rule of that algorithm, and then it uses a graphics card to do the arithmetic. His algorithm will be geometric superposition. So it's hard to find this bitcoin now. There is one of them. Well, you download the roaming browser. He has one called symbiotic coin. That is to say, when you usually surf the Internet, use this browser. You'll generate some virtual coins. Then it can be changed into RMB. I'm not quite clear about his ratio.
3. 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?

4. The decline in the use of cash in the future may accelerate the efforts of the central bank in the field of digital money. The European Central Bank believes that is the same trend.
5. Ether clown is based on Ethereum blockchain to develop a digital phone, blockchain game with collection value! Now I'll introce it
1. The proction of clowns
the proction mechanism of clowns can be divided into two kinds, one is the official output, the other is the breeding output between two clowns
one official clown is proced every 15 minutes, and the total number is only 50000. At certain times, the official will also release some strange clowns with special shapes. The price of the original clown is the average of the prices of the last five clowns in the market
two clowns of different genders can reproce in the breeding center of the market. In each breeding pair, one clown who plays the role of father can receive the breeding fee paid by the other party (maternal Master). After breeding, there is a certain recovery period, which is related to the clown's genes. The clown in the role of mother will have a period of pregnancy, and she will not be able to breed with other clowns until she gives birth to her baby. There is no limit to the number of breeding times of each etheric clown, but the recovery period and pregnancy period will increase with the number of breeding times< Each clown's appearance is determined by the tamperable genes stored in the smart contract, and each gene is unique, so each clown is unique
the appearance of a clown is composed of eight parts, each part of which can be divided into ordinary and rare attributes. The number of rare attributes is less than that of ordinary attributes, which makes the clown with rare attributes more precious
the appearance of a clown born in breeding is closely related to his parents and the genetic genes carried by his parents. The offspring have a high probability of inheriting the shape of some parts of his parents, so that their parents' good genes can be inherited, and it is possible to mutate and become a completely different clown from his parents
3. Clown trading
etheric clown can be directly used for trading
sell: users can choose clowns to be auctioned in the market, and they can sell their own clowns. When selling, users need to set the highest starting price, the lowest acceptance price and the auction time. The Dutch auction is adopted in the auction. During the auction time, the highest price set by the seller is graally transferred to the lowest price. If the owner is not willing to sell at a low price, a longer auction time can be set or the clown can be sold off the shelves
buy: the buyer selects the clown on sale in the market and pays ether to buy the clown he likes. When the buyer purchases, the transaction will be concluded at the auction price at the current time point. If you have a favorite clown, but feel that the price is not suitable for the time being, and want to pay more attention, you can collect the clown after you like it. Later, we can understand the dynamic of the clown through "my attention"< There are four kinds of clown attribute values: growth value, strength value, agility value and wisdom value. Generation 0 clowns get the value of each attribute randomly, and the non generation 0 clowns are mainly inherited
attribute values can be changed by eating food
after the clown's growth value reaches the requirement (100 points), he can go to the factory to earn money (ETH). Different kinds of factories need different clowns. Dream college needs the wisdom of every working clown. Clowns with more than 800 points of wisdom go to Dream Academy of Sciences to work, and their income can get bonus. If a clown with less than 300 wisdom goes to work, his income will be reced to
a part-time job will consume physical strength. The total physical strength is 120 points. It consumes 1 point every 12 minutes and can work up to 24 hours. During the period of not working, physical strength can be recovered, a little every 8 minutes
when the time reaches 0 o'clock or the clown's physical exertion is completed, the clown's work income will be settled according to the actual working hours at 0 o'clock every day. When every 12 minutes is a work, less than 12 minutes will not be counted
5. Clown food and feeding
owners can buy spinach, beef, carrots, walnuts and other food through the mall to feed clown pets
the price of food is related to the selling price of original clowns on the platform the day before. So the owners can hoard some food when the price of food is low
feeding spinach is helpful to growth value, beef corresponds to clown pet's strength value, carrot corresponds to agility, walnut corresponds to wisdom
the clown can only eat one food a day. We suggest that spinach should be fed in the early stage to meet the working conditions as soon as possible, and then according to the natural properties of clown in the later stage. When working, choose the type of factory with the highest attributes to work.

6. There are many old desktop computers in the purchase of independent graphics card, add an independent graphics card can play a good role! Now the price of mainstream graphics cards on the market ranges from more than 200 to 1000. Of course, adding independent graphics cards is the most expensive of these upgrade methods. If you think it's too expensive for you to upgrade a four or five hundred graphics card, you'd better give up the idea of playing games! l
7. To answer this question, is the foreign currency presented in stationery illegal? This is a violation of the law, because it is not a gift.
8. Mineral resources belong to state-owned assets. Any natural person or organization operating mining must apply to the relevant departments of the state for a franchise license, strictly perform the relevant obligations and responsibilities, and carry out safe proction. Only in this way can the mining of natural resources be carried out legally and legally.
9. The way to solve the rail corrosion is to change the water-based cutting fluid into oil-based cutting oil, emulsion oil, or change the cutting fluid with poor cleaning effect, or choose the rail oil with molybdenum as the anti-wear raw material
experienced operators of CNC lathes and machining centers must have met that the antirust effect of antirust cutting fluid used in daily proction is very good, and the antirust cycle between processes of procts after processing can also achieve the expected effect, but rust often appears on the worktables and guide rails of CNC lathes and machining centers
since the antirust performance of cutting fluid is very good, why does the proction equipment rust? Does the period have anything to do with the cutting fluid? What's the relationship?
if the antirust performance of the machined workpiece is acceptable, the viewpoint that the antirust performance of the cutting fluid is poor can be basically ruled out, and the rail corrosion directly caused by the cutting fluid can also be ruled out
this is e to the oil applied on the door of the guide rail. Guideway oil is usually composed of base oil, mineral oil and some sulfur and phosphorus antiwear agents. During the circulation process, cutting fluid contacts with guideway oil to proce part of oil-water mixture, namely oil sludge
oil is lighter than water, and oil absorbs most of the alkali and antirust components in the cutting fluid. Combined with the effect of water, the guide rail is very easy to be oxidized and rusted
this is not the main reason for the corrosion of the guide rail. The main reason is that the anti-wear agents such as sulfur and phosphorus in the guide rail oil are hydrolyzed under the action of water, which is the main component of the cutting fluid. Sulfur and phosphorus have serious corrosivity to steel parts, which is the main reason for the corrosion of the guide rail.
