In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining
the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig
another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful
extended data
currency characteristics of bitcoin
1, decentralized
bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership
controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost
bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution
5, no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining
users can explore the computing power of different hardware on many platforms
2. 99% of them are deceiving. It's deceiving to say how much it will appreciate. It's just a technology, its application is valuable.
3. Cryptoclone is a digital and collectable blockchain game based on Ethereum blockchain. The use of ether money to adopt clown pets can not only resell them, but also use them to breed a new generation of clown pets with strange shapes. It can also cultivate them and let them work to make money, which makes the digital collection of clown pets more sustainable and playable. At the same time, based on the characteristics of blockchain development, all clown pet trading, working, breeding, feeding and other values can never be tampered with, ensuring the security of assets
1. The proction and breeding of clown pets
the proction mechanism of clown pets can be divided into two types, one is the official proction (zero generation clown pets), the other is the breeding between two clown pets
the official clown pets can be divided into two categories: ordinary zero generation clown pets and special clown pets. Ordinary zero generation clown pets proce one every 15 minutes, and the total number is only 50000. The appearance of ordinary clown pet is composed of 8 parts. The attributes of each part can be divided into ordinary and rare. The number of rare attributes is less than that of ordinary attributes
Special clown pet is a variant of clown pet. Special clown pets are divided into three categories: creation clown pets, special clown pets and strange clown pets, all belong to generation 0 clown pets. The creation clown pet is the creator of the whole clown pet world. There is one male and one female. It is no longer bred and belongs to the platform. It can't be traded within one month after the release of cryptotown. It will be auctioned after one month. The lowest price is 5 times of the average selling price of all clown pets proced by the platform at the time of auction. Clown pet is a kind of customized clown pet in operation activities, which is limited in quantity and cannot be bred. Strange clown pets are some funny looking clown pets. After they are launched on the platform, they can be purchased directly or mutated ring breeding
two clown pets of different genders can reproce in the breeding center of the market. In each breeding pair, one clown pet bearing the role of father can receive the breeding fee paid by the other (maternal owner). After breeding, there is a certain recovery period, which is related to the clown pet's gene. The clown pet in the role of mother will have a period of pregnancy, and she will not be able to breed again until she gives birth to the baby. There is no limit to the number of breeding times of each etheric clown pet, but the recovery period and pregnancy period will increase with the number of breeding times
male clown pets can click breeding on the details page of clown pets in the "my" interface to carry out hanging list breeding. If there are genes favored by female clown pets, or the price is particularly suitable, female clown pets will soon breed with them to proce the next generation
female clown pets can go directly to the "market" and choose their favorite male clown pets "to be bred". After paying the breeding fee, they can breed the next generation together
2. The appearance of clown pet
the appearance of clown pet is composed of eight parts: eyes, mouth, nose, hair and hat, body shape, pattern shape, pattern color, skin color and clothing color. The attributes of each part can be divided into common and rare. The number of rare attributes is less than that of common attributes, which makes the clown pet with rare attributes more precious
each clown pet is born with 54 gene codes, which are divided into three groups, 18 in each group. The first two groups represent the genetic genes of the clown pet's grandparents and parents, and the third group represents the clown pet's own genes. The 18 genes are divided into nine groups, representing nine attributes, including background color, eyes, mouth and nose, hair and hat, body shape, pattern shape, pattern color, skin color and clothing color. Gene codes and random functions are written on the chain and cannot be changed. The appearance of the clown pet is closely related to the parents and the genetic genes carried by them. The offspring have a higher probability of inheriting the shape of some parts of their parents, which makes the parents' good genes inherited and may also mutate to become a completely different clown pet from their parents. In order to get a baby clown pet with rare attributes, please try to choose those clown pets with more specific attributes for breeding
the appearance of each clown pet is determined by the tamperable genes stored in the smart contract, and each gene is unique, so each clown pet is unique
3. Clown pet trading
selling clown pets
users can choose clown pets to be auctioned in the trading market, and can sell their own multiple clown pets. During the auction, 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 pet can be sold off the shelves
buy clown pets
the buyer selects the clown pets on sale in the trading market and pays ether to buy their favorite clown pets. When the buyer purchases, the transaction will be concluded at the auction price at the current time point. If you have a favorite clown pet, but feel that the price is not suitable for the time being, and want to pay more attention, you can like it and collect it. Later, you can learn about the dynamics of the clown pet through "my attention"< There are four attribute values of clown PET: growth value, strength value, agility value and wisdom value. Generation 0 clown pets get the value of each attribute randomly, and the non generation 0 clown pets are mainly inherited
attribute values can be changed by eating food. Please refer to point 5 of this page for the relationship between attributes and corresponding food
working
after the growth value of clown pet reaches the requirement (100 points), you can go to the factory to work and earn money (ETH). Different kinds of factories need different clown pets. When the clown pet attribute is higher than 800, go to the factory with the corresponding attribute to get an additional bonus. On the basis of 800, for every 10 points higher in the attribute, the revenue can be increased by another 1%. If the strength of clown pet is 801, he can get basic income * (1 + 1%) by working in a power factory. When his strength reaches 811, he can get basic income * (1 + 2%), and the maximum bonus is 20%. When the clown pet attribute is lower than 300, the income from working in the corresponding factory will decrease. For every 10 points lower, the income will decrease by 1%, and the maximum will be reced to 20%
each owner can allow up to three clown pets to work at the same time
the basic income of working
the working system is a part of the platform. The platform will allocate 20% of the previous day's income every day as the basis for calculating the benchmark income. If the clown pet has a profit bonus, the bonus part of the income can reach up to 24% of the previous day's income. Working income is settled by 12 minutes as a working hour, with 5 working hours per hour. Benchmark income = daily income before the platform * 15% / (number of jobs * 24 * 5) * [working time (minutes) / 12]
when the time reaches 0 o'clock or the clown pet's physical strength is 0, the work income of the clown pet will be paid 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
jobs
in the early stage, we opened a total of three factories with a total of 150 jobs. Hosts can sign up for work as soon as possible. If you don't sign up successfully, you can go to the factory interface when you have time. Other clown pets can sign up for work if they leave their places after work
when the total number of owners of the zero generation clown pet on the platform reaches 900, we will open 3 new factories to 300 working seats. The number of work places will continue to increase as the total number of alt clowns and hosts increases
physical strength
physical strength is 120 points in total. Working will consume physical strength, consuming 1 point every 12 minutes, up to 24 hours. During the period of not working, physical strength can be recovered, a little every 8 minutes
5. Clown pet food and feeding
owners can buy spinach, beef, carrots, walnuts and other food through the mall to feed clown pets
feeding spinach is helpful to growth value, beef corresponds to clown pet's strength value, carrot corresponds to agility, walnut corresponds to wisdom. Each food can add 10 corresponding attributes. After property growth, it will not be reced
the price of food is related to the selling price of original clown pets on the platform the previous day. Spinach accounts for 20% of the average trading price of generation 0 clown pets on the platform the previous day, and the other three foods account for 15%. Owners can hoard some food when the price of food is low
clown pets can only eat one food per 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 pets in the later stage. When working, choose the type of factory with the highest attributes to work
6. It's more lovely to bask in the sun
in order to increase the social attribute of the game, we added the "square" section. Many lovely owners and clown pets gather in the square to share their stories. If you adopt a very ugly and cute clown pet, you can share it with us to let us know our style.

At present, there are not many videos on the market for systematic learning of blockchain, and self-learning of blockchain is still relatively rare. You can apply for classes. Black horse programmers will open a new blockchain discipline. Teachers will teach in an easy-to-understand way and explain in simple terms. You can certainly learn it. Source area video network, want to understand the blockchain, watch video tutorial here
5. Comparison trading platform, such as bitcoin
6. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block.
7. Blockchain game is a game that allows you to make money in your spare time. However, the current blockchain game feels that mining world Qicai is OK, and the rest are scalpers, which are not very interesting
8. 1. Most people don't know what blockchain is
compared with traditional stocks, real estate, bonds, gold and so on, blockchain assets are a very abstract and virtual form of assets. Represented by bitcoin, blockchain assets are a very professional computer language and program operation mode, and there is no credit endorsement from any country behind them, In this case, although the operation logic of decentralization has been completed, its experiment is still in the initial stage and development stage. Participating in relevant investment is actually a kind of brave adventurer behavior
2. The price of blockchain assets fluctuates violently
many blockchain projects are completely dependent on community operation and market speculation because there is not much support from the use level of entities, so it is difficult for investors to hold blockchain assets from the perspective of value investment, which leads to frequent capital flow, and the situation of price fluctuations has become a normal. A blockchain related token can soar by 500% in a day, or fall by 90% in a few hours. This kind of drastic price fluctuation is not affordable to ordinary investors
3. The uncertainty of national policies is too great
as an underlying technology, blockchain has basically accepted its value all over the world. However, as the "companion proct" of blockchain, there are still great controversies on national policies, and with the continuous increase of digital currency trading volume, the impact on the global financial market is also increasing. At present, the daily trading volume of the whole digital currency field exceeds US $60 billion, which is comparable to the trading volume of China's Shanghai and Shenzhen stock exchanges, or the average daily trading volume of the New York Stock Exchange. It is impossible to continue to operate outside the supervision. There is a very large regulatory game cycle, and the policies of various countries in this regard may be introced one after another, The impact on the market cannot be ignored
4. All kinds of blockchain projects are good and bad.
blockchain technology is originally a very basic architecture technology. At present, e to the global pursuit of funds, many project parties who have nothing to do with blockchain begin to use the concept of blockchain to design procts, And can complete the writing of the white paper of blockchain in a very short time, and then raise market funds. In this case, the technical threshold of the whole blockchain has been lowered. Many companies without the strength and willingness of blockchain development have developed the concept of blockchain purely to obtain financial support, resulting in the flooding of projects. The gap between projects is widening, but ordinary investors are difficult to identify and easy to fall into the trap
5. Currency speculation is not equal to blockchain investment
at present, there are many views that blockchain and digital currency are a whole. You can't develop blockchain technology while suppressing digital currency. I agree with this logic, but currency speculation is not the same as blockchain investment in the real sense. The thing with real investment value must be the thing with scarce supply. If any digital currency is issued, it can represent the application value of the blockchain and bring some innovation to the society. Then any blockchain technology team that can issue digital currency can issue dozens of digital currencies and change its name in a very short time. Therefore, digital currency itself has little logical relationship with blockchain assets. Blockchain projects must be a market with obvious scarcity, but digital currency does not have great scarcity. This is like saying that any Internet company can develop a chat software similar to wechat, but the chat software itself does not have much value. The real value lies in how many people participate in the chat software. Digital money is just a chat software. The current situation is that everyone is frying the software, and few people are concerned about what is on the software.
6. Short term overheated, easy to be used by lawless elements
the particularity of the blockchain instry is that many of its ecology has become very financial. In the whole process of operation, funds will be very concentrated, and most of the links are related to funds. From raising funds by ICO to sending tokens to investors, to online trading of exchanges, and trading of tokens by users in exchanges, the whole process is almost full of financialization. If the practitioners are not professional enough, have no self-discipline ability, and lack of supervision, then every link may be used by criminals to manipulate the market and obtain all kinds of illegal profits< In order to catch up with the next round of financial technology and digital revolution, Japan holds a very open attitude towards bitcoin and other transactions. Digital currency transactions denominated in yen account for half of the whole French currency trading area in the world, Japan hopes to use digital currency to revive its financial competitiveness. The United States hopes to use mainstream financial markets, such as futures and options derivatives market, to tame bitcoin and make it another powerful tool for us dollar hegemony. And China is also trying to promote sovereign cryptocurrency, one of the important purposes is to promote the internationalization of RMB. The field of digital currency and blockchain assets is likely to become the next big country's game and contention point, which will virtually increase the systematic risk to investors. It's hard to know what unexpected policies appear behind this big country's game and what impact they will bring to the whole market
8. The threat of quantum computer
blockchain generates a set of self-motivated system to ensure its self-operation under decentralized conditions. Most of them use asymmetric encryption, and use the corresponding public key to verify the transactions signed by the private key, so as to ensure that bitcoin and other blockchain assets can only be used by legitimate owners. But quantum computer can solve the problem of asymmetric encryption. Quantum computer can calculate the private key from the public key in a few minutes. After knowing all the private keys, people with quantum computer can spend bitcoin and other digital currency at will. Of course, when the quantum computer will come out is also a problem. The digital currency protocol is constantly adding new encryption standards, but the potential threat brought by the quantum computer has to attract the attention of investors
9. There is a possibility of a big reversal in the supply and demand level
the market value of the blockchain token market has hovered around one trillion US dollars. Although OTC funds are still pouring in, the stability and growth rate of the capital inflow are questionable. The supply of encrypted digital currency is a very embarrassing thing. From the perspective of a single digital currency, the total amount is strictly limited. For example, there are only 21 million bitcoins, but the threshold of issuing encrypted digital currency is getting lower and lower. Anyone and any organization can issue encrypted digital currency anytime and anywhere, and the supply is almost unlimited. On the other hand, the increasing transaction cost is restraining the demand side. At present, investors in the transaction link need to pay the transaction fees in the exchange, and also pay the miners' fees when transferring money. If countries begin to tax digital currency transactions in the future, it means that this market will have to bear more operating costs without generating its own profitability, If coupled with the increasing supply level, the overall market supply and demand expectations may reverse in a moment
10. The block chain assets are lack of legal protection
it is not uncommon that global digital currency exchanges are "hacked", and in the process of all kinds of over-the-counter and on-the-spot transactions, fraud also occurs from time to time, and the legal protection for investors is very limited. Especially for domestic investors, once they are stolen or cheated because of trading digital currency, it is almost difficult to recover effectively. Due to the lack of intermediary guarantee from banks and other levels, the security of digital currency is entirely under their own responsibility. Although this is in line with the logic of self preservation of private property, it also brings greater uncertainty to the storage and transaction of digital currency assets. Before there is no complete legal system to protect the rights and interests of personal digital currency assets, the legal security of investment in blockchain related assets is a very serious problem.
compared with traditional stocks, real estate, bonds, gold and so on, blockchain assets are a very abstract and virtual form of assets. Represented by bitcoin, blockchain assets are a very professional computer language and program operation mode, and there is no credit endorsement from any country behind them, In this case, although the operation logic of decentralization has been completed, its experiment is still in the initial stage and development stage.

the market value of the blockchain token market has hovered around one trillion US dollars. Although OTC funds are still pouring in, the stability and growth rate of the capital inflow are questionable. The supply of encrypted digital currency is a very embarrassing thing. From the perspective of a single digital currency, the total amount is strictly limited. For example, there are only 21 million bitcoins, but the threshold of issuing encrypted digital currency is getting lower and lower. Anyone and any organization can issue encrypted digital currency anytime and anywhere, and the supply is almost unlimited. On the other hand, the increasing transaction cost is restraining the demand side. At present, investors in the transaction link need to pay the transaction fees in the exchange, and also pay the miners' fees when transferring money. If countries begin to tax digital currency transactions in the future, it means that this market will have to bear more operating costs without generating its own profitability, If coupled with the increasing supply level, the overall market supply and demand expectations may reverse in a moment
10. The block chain assets are lack of legal protection
it is not uncommon that global digital currency exchanges are "hacked", and in the process of all kinds of over-the-counter and on-the-spot transactions, fraud also occurs from time to time, and the legal protection for investors is very limited. Especially for domestic investors, once they are stolen or cheated because of trading digital currency, it is almost difficult to recover effectively. Due to the lack of intermediary guarantee from banks and other levels, the security of digital currency is entirely under their own responsibility. Although this is in line with the logic of self preservation of private property, it also brings greater uncertainty to the storage and transaction of digital currency assets. Before there is no complete legal system to protect the rights and interests of personal digital currency assets, the legal security of investment in blockchain related assets is a very serious problem.
