Master blockchain
in short, blockchain is a community-based technology, which can make value exchange more secure. Blockchain is their name 
therefore, chain operation has a huge impact on the people, creating the greatest value for the enterprise and bringing more convenience to the people
first, define the
blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain
Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network securityin the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent
In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high fees1. Jinrong China Financial Instry Co., Ltd.
this is a digital currency trading platform in Hong Kong. At the beginning of trading, it developed on the principle of safeguarding the rights and interests of customers. Similarly, in order to expand trading customers, the company launched the privilege of opening accounts free of charge, and gave customers some concessions in some festivals, This is an important reason why the enterprise takes the first place in the domestic formal blockchain platform
2. Bitfinex
is a digital currency trading platform in Hong Kong, China. It is one of the largest cryptocurrency exchanges in the world. It occupies an important position in the world's cryptocurrency trading and circulation. It also provides the world's most liquid registration policy and plays an important role in the world's trading operations, At present, it occupies the second place in the domestic regular blockchain platform
3. Fire coin network
this is an earlier digital currency trading platform in China, mainly trading bitcoin. As the third instry of domestic regular blockchain platform, it is the trading platform with the largest bitcoin trading volume in China. Many new digital asset trading platforms have been developed under the company, For the future development of the foundation
This is a digital currency trading platform jointly established by some digital currency enthusiasts, and its founder is Zhao CHANGPENG. In fact, this trading platform didn't attract much attention at the beginning. With the continuous operation of the company and the founder's understanding of digital currency, this enterprise has become the top four domestic regular blockchain platforms, which shows the power of this platform This is one of the most popular digital asset trading platforms in the world. There are many kinds of digital currencies for trading, and their main functions are cash out and derivative trading. They are well-known in the world's exchangesdecentralization means that there is no separate intermediary
Specifically, users can share the idle storage space and bandwidth resources of cat disk, and these resources will be output to companies such as content, video, game, blockchain, etc. cat disk company will convert the legal currency and various digital currencies paid by the latter into bitcoin, and users will get the corresponding bitcoin income. This is also the unique mining mode of cat disk
why reward bitcoin
because similar procts on the market reward users with points, diamonds and other rights and interests issued by relevant companies, and most of these rights and interests are of low or no value. In addition, those projects that once seemed to be hot are now almost withered, and the early players may benefit, while the late players will lose all their money
as we know, bitcoin is the anchor currency in the digital currency world. Cat disk directly uses bitcoin to motivate users, and users can pick up the coin to their wallet at any time, and their income can be guaranteed. Moreover, the risk of bitcoin breaking is almost zero, and the user's income will be more lasting and stable
how is the mining income distributed when it comes to distribution, we should first introce the concept of "storage power", which is directly linked to the income of cat disk users. Storage power is an index based on users' shared storage space, bandwidth and online time. The larger the storage space, the faster the bandwidth speed and the longer the online time, the larger the storage power, and vice versa the cat disk gains revenue by sharing storage bandwidth resources, and users can check the revenue through app every day, that is, how much bitcoin they earn. The profit distribution of maopan mining is not random, but through a series of calculations. In short, users' daily income depends on their personal storage capacity, all users' storage capacity and the amount of money issued each day. The calculation formula is as follows: single user's daily income = single user's daily storage capacity / all users' daily storage capacity * Daily currency amount it can be seen that users' daily income is positively correlated with the daily storage capacity index and the daily currency amount, and negatively correlated with all users' daily storage capacity index what is the amount of money issued every day the cat disk integrates the storage and bandwidth resources shared by users, provides storage and bandwidth services to the demander, and converts various digital currencies paid by the other party into bitcoin for distribution to users. How much bitcoin is issued every day depends on the actual business situation, so there is no way to give specific figures for the time being. What we can make clear is that, unlike other mining procts, cat disk does not issue its own currency or restrict the mining of a specific kind or several kinds of currency. Instead, it earns various digital currencies paid by others. These currencies are all market currency. Cat disk converts these currencies into bitcoin and distributes them to users note that all the currencies are negotiable, and the more storage nodes, the more business, the higher the overall mining revenue; For other mining procts, the amount of money that can be mined is limited or issued by the owner. With the passage of time, there will be more and more mining machines, and the mining income will be less and less
No, all right. If block currency is used for trading in the game or something. It's likely to touch the penalty area. No contact< br />
in 2019, the expenditure scale of China's blockchain market will be close to US $300 million
according to the statistical data of in depth analysis report on business model innovation and investment opportunities of China's blockchain instry , released by foresight Instry Research Institute, as of 2017, the expenditure scale of China's blockchain market is only US $83 million. In 2018, the expenditure scale of China's blockchain market will reach US $160 million. It is predicted that the expenditure scale of China's blockchain market will be close to US $300 million in 2019. At this stage, the overall market scale of blockchain is small, because most blockchain projects in the market are in the trial stage, with little investment. On the other hand, many enterprises have realized the potential of blockchain and plan to increase the budget in the future. Affected by this, China's blockchain market will usher in rapid growth. It is estimated that the market expenditure will reach US $1.95 billion by 2023, and the average annual compound growth rate will be 60.51% from 2019 to 2023
statistics and forecast of China's blockchain market expenditure scale from 2017 to 2023
data source: Analysis on adverse factors of China's blockchain development sorted out by the prospective instry research institute
1. Immature technology. At present, blockchain technology is not mature in system stability, application security, business model, etc., which can not meet the requirements of "high efficiency and low energy", "decentralization" and "security" at the same time. First, performance. The transaction throughput that can be carried out on the blockchain is not high, and the current block capacity is very small, which leads to network congestion, and it is difficult to meet the needs of high-frequency business. Many projects are also starting to optimize, but there is still a certain distance from the transaction throughput of real scenes such as banks and stock exchanges. Second, consensus mechanism. In terms of energy consumption, consensus algorithms such as workload proof consume a lot of energy and cost, which makes blockchain waste a lot of network computing power and pairing power; In terms of types, there are too few types of blockchain consensus mechanisms at present. In the future diversified business scenarios, more abundant consensus mechanisms are necessary to adapt. Third, security. Privacy protection, harmful information on the chain, smart contract vulnerability, consensus mechanism and private key protection, computing power attack, cryptography algorithm security and other issues make the blockchain face a severe situation of platform security and application security. Fourth, the database problem. Different from traditional databases, blockchain applications require a lot of write operations, hash calculation and verification operations. The database system for blockchain is still a difficult point to break through
2. Unclear application scenarios
currently, the blockchain project is still in the exploration stage, and no specific landing scenarios can be found. At present, the more promising fields are finance, sharing economy, Internet of things, public services, etc., but from the perspective of the existing blockchain technology maturity, there are still many problems in the application of blockchain, and there is still a gap from the actual use. First, the immaturity of blockchain technology restricts the implementation of commercial applications. At present, although there are many kinds of blockchain core technologies such as privacy protection algorithm and consensus mechanism, they generally do not have commercial availability. Second, the application mode of blockchain is still in exploration, and the "irreplaceable" advantage of blockchain has not been reflected. Blockchain itself represents a consensus system, so we should build a consensus system in line with the corresponding business scenarios from a higher level, rather than just "business + blockchain". There are many users in China, and the business scenario is complex. Moreover, any commercial proct will involve a very large flow and population. The current blockchain technology can not meet the demand
3, lack of professional talents
blockchain technology is a multi-disciplinary and interdisciplinary technology, which mainly involves operating system, network communication, cryptography, mathematics, finance, proction and so on. However, at present, there are still deficiencies in interdisciplinary and fields in China, and the supply of talents in related fields is seriously insufficient. On the one hand, there is a large gap of R & D technical talents. Blockchain technology research and development mainly focuses on go, JavaScript, C and C + programming languages, and new smart contracts use Haskell, Ocaml, rhoang and other new functional programming languages. In China's talent market, there is a big gap for technical talents with senior R & D experience in relevant languages. On the other hand, there is a lack of bottom design talents. Different from R & D technical talents, blockchain bottom system architecture designers need to master a number of interdisciplinary professional skills, not only to deeply understand the block chain bottom design principle, but also to have the system architecture design experience, but also to master the business logic of specific application scenarios. Although some colleges and universities have launched interdisciplinary ecation and blockchain special skills discipline setting, professional talents are still very scarce
analysis of favorable factors for China's blockchain development. In January 2017, the Ministry of instry and information technology issued the development plan of software and information technology service instry (2016-2020), which proposed that the innovation in blockchain and other fields should reach the international advanced level. In August 2017, the State Council issued the guidance on further expanding and upgrading information consumption and continuously releasing the potential of domestic demand, proposing to carry out the pilot application of new technologies such as blockchain and artificial intelligence. In October 2017, the State Council issued the guidance on actively promoting the innovation and application of supply chain, which proposed to study the use of blockchain, artificial intelligence and other emerging technologies to establish a credit evaluation mechanism based on supply chain
in March 2018, the Ministry of instry and information technology (MIIT) issued the key points for standardization of informatization and software service instry in 2018, proposing to promote the establishment of the national informatization and instrialization Integration Management Standardization Technical Committee, and the national blockchain and Distributed Accounting Technology Standardization Committee. In June 2018, the Ministry of instry and information technology issued the instrial Internet development action plan (2018-2020) to encourage the application and research of emerging cutting-edge technologies such as edge computing, deep learning and blockchain in the instrial Internet
since the blockchain was listed in the 13th five year plan for national informatization for the first time in 2016, the national government has paid more and more attention to the blockchain. 24 provinces and cities or regions, including Beijing, Shanghai, Guangdong, Hebei, Jiangsu, Shandong, Guizhou, Gansu and Hainan, have launched dividend policies to carry out the layout of the blockchain instry chain, Actively explore instry applications based on blockchain
At present, China's blockchain technology continues to innovate, and the blockchain instry graally takes shape, and has begun to be applied in supply chain finance, credit reference, proct traceability, right trading, digital identity, electronic evidence and other fields, which is expected to promote China's economic system to achieve technological change, organizational change and efficiency change, To make important contributions to the construction of a modern economic system. With the continuous influx of entrepreneurs and capital, the number of enterprises is increasing rapidly. The application of blockchain will accelerate the landing, boost the high-quality development of traditional instries, accelerate the instrial transformation and upgrading, use blockchain technology to "rece costs" and "improve efficiency" for the real economy, and boost the standardized development of traditional instries. In addition, blockchain technology is becoming a new business form and a new driving force for economic development. Blockchain technology is promoting a new round of business model reform and becoming an important support for building a social system of integrity In the past, the circulation of physical banknotes was difficult to trace, but with the application of blockchain technology, the flow of all digital assets will have a "chain" to check. For example, in the financial field, blockchain is expected to solve the pain points and difficulties in the payment field, rece the complexity of transactions, improve the end-to-end speed of transactions, rece the communication cost in the transaction process, and improve the transparency and non tamperability of transaction records. The cost of reconciliation, clearing and settlement among financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution among financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In addition, the application of blockchain will also extend to many fields, such as health care, ecation, charity, social management and so on. The market prospect is very broadIn a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
blockchain
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access A new distributed infrastructure and computing method using intelligent contract composed of automated script code to program and operate data
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. It's more lovely to bask in the sun
it's OK. Go to the square and have a look. Here gathered a lot of lovely owners and clowns, if you adopt a very ugly cute clown, also bask in, let everyone know our style.
