Who invented the mining machinery regional chain

1. With the development of cryptocurrency, the "blockchain technology" has become popular. In China, both giant companies such as batj (network, Alibaba, Tencent, and Jingdong) and companies like didi and ofo are actively exploring blockchain technology. Throughout the world, Wal Mart, MasterCard,
IBM and giant automobile manufacturers are trying to use blockchain technology to solve instry pain points. In addition, there are "declining" enterprises such as Kodak of Japan, hoping to fight a "turnaround battle" through blockchain
What does these phenomena show? This shows that the technology of block chain has great commercial value. Everyone hopes to cultivate a new world on this unknown land. So, with the development of blockchain technology this year, it has not only been a simple underlying technology, but also formed a complete ecosystem. Now let's talk with you from two aspects of "coin circle" and "chain circle": what is the ecosystem of blockchain, and let's understand the whole picture of blockchain instry
the first section of the coin circle
in the coin circle, there are always several terms: project party, exchange, media, mining machinery manufacturer. Next, let's take a detailed inventory of what's going on
first, the project side of the coin circle can be understood as follows: all those who issue tokens are the project side. Attention, it's a coin ring. There are also some project parties that don't issue money, such as Alibaba, Tencent and Netease, which are also doing blockchain projects. They don't issue money and only focus on technology. Then these project parties that don't issue money mainly focus on the role of blockchain in data security and supply chain, which we will talk about later
let's return to the topic of coin circle project parties. For example, yilaiyun and BoChang, which are more controversial recently, are the project parties of coin circle, as well as blockchain games, which are more popular recently. They also belong to coin circle project parties
one of the subversive aspects of the coin circle project is the combination of the project and the token, which directly replaces the equity with the token, and the token can be directly circulated. This is a very revolutionary point, so that many initial projects can be more convenient for financing. After financing, the feedback token can be circulated on the digital currency trading platform, and the investors can also exit very well
this "financing investment" approach seems to be another way to realize the listing and trading of equity in disguised form
therefore, it is such a mode that makes the project side of the coin circle the nearest place to the money. They can easily circle the money, and of course they can't resist the temptation, or they have been planning for a long time and run away after circling the money. The detailed process of token issuing by the project side is generally as follows:
the first step is to build a token system, which is similar to an app application. This is not very complicated, because Ethereum is open source, similar to Android Apple system, on which developers can develop specific applications
the second step is to write a white paper, which is similar to the business plan. The white paper is similar to the business plan, mainly including the team situation, technical situation and other information of the project
the third step is to find someone to do endorsement, and find some influential instry bigwigs to promote
the fourth step is to promote marketing, find some blockchain media to push soft articles and pull cooperation, which we will mention below
the fifth step is to find financing
Step 6: go to the stock exchange, and the token begins to spread widely
Second, the exchange
with the project side, let's talk about the exchange. If the project side is a procer, then the things they proce have to be sold and traded, right? The exchange is a trading place for the token of the project party. If the token of the project side is similar to the stock, then the exchange of the currency circle is similar to the secondary market of the stock market. However, the exchange of the currency circle has more power. It has the right to audit the currency, and can decide whether to put the currency in or out
of course, if the project party wants to pay the exchange a huge amount of money charging fees, the investors who trade in the exchange also need to pay the handling fee or withdrawal fee, and the rules of the handling fee and withdrawal fee of each exchange are different. In fact, the currency fees, handling fees and cash withdrawal fees constitute the profit model of the currency circle exchange. Of course, in addition to these three profit models, the profit model of the exchange includes the "market maker" business to earn the price difference, that is, the exchange creates liquidity through continuous trading, acts as a market maker and earns the price difference at the same time
at present, e to the increasingly fierce competition in the instry, there will be less and less currency fees and handling charges, or even no need, so the proportion of conventional profits will be less and less, which leads to the emergence of other profit models, such as platform currency and leverage handling charges. Let's talk about platform currency first. Platform currency is the currency issued by the exchange: okb and coin an belong to platform currency. These platform currencies issued by the exchange can be exchanged for BTC and eth. At the same time, the appreciation of platform currency's own value can lay a solid material foundation for the development of the exchange. For users, holding platform currency can enjoy the benefits of commission discount, platform dividend, special activities of the exchange, etc, This is platform currency. Leverage service charge refers to the currency financing function on the platform, which supports leveraged transactions and charges a certain proportion of service charge to currency financing users
all of the above are actually ecosystems constructed through the exchange's own resource output. Now, the exchange is still actively planning the whole instry to obtain income, such as the establishment of capital, mine pool, wallet, incubator, Engineering Institute, fund and other ways. We believe that if the exchange wants to develop for a long time, it must lay out the whole instry chain, find new breakout points of the instry, and build a complete ecosystem. Therefore, the proportion of strategic profits should be increased
3. Blockchain media
in the past two years when blockchain is hot, there are not only a lot of project parties, but also media. At present, there are about 200 well-known blockchain media. The content on the blockchain media platform is about the following points: policy, hacker, exchange, boss and project party. In addition to words, the operation mode of blockchain media also includes community activities, such as inviting "big guys" to share in the group, so as to achieve a precipitation of high-quality content and earn some traffic at the same time
Why do we have to mention blockchain media? It's because there are some differences between blockchain media and the media in our impression. What's the difference? The difference is that there are some interest relationships between blockchain media and the above mentioned project parties and exchanges. We just said that the project side is like a "procer" and the exchange is like a "sales market". Then, the role of the media is like "advertising platform & quot;. If the project wants to sell well, it needs publicity and advertising, then blockchain media plays such a role. Therefore, the investors of some blockchain media are the project side and the exchange
recently, there has been a bear market. Many blockchain media have laid off employees on a large scale. The reason is nothing more than the shortage of projects and funds. Therefore, it is far from enough for blockchain media to rely solely on the investment of the project side, the exchange and the advertising revenue. When the bear market comes and the project side and the exchange are affected, then the media is bound to face a very cruel winter. As a result, many blockchain media are also doing token issuing by project parties (the most typical are content communities such as coin and coin car, which belong to a media platform and are also doing token issuing by project parties), or some blockchain media are doing business such as wallet selling, mining machine renting and computing power
however, we believe that blockchain media, as the media, still play the role of guiding public opinion. Therefore, we should return to the essence and be a place to deliver instry value information, rather than a place to pile up advertisements. Therefore, blockchain media should keep up with the development of technology to realize its own survival and development. Relying on the advantages of blockchain technology and based on the consensus mechanism in the token system, it can realize the reasonable distribution of the interests of the media instry. In this regard, it may have a certain imagination< Fourth, mining machine manufacturers
in the final analysis, bitcoin mining is the competition of computing power. The stronger the computing power, the greater the probability of bitcoin mining. Therefore, in the business system of the whole coin circle, mining machinery manufacturers are a very important existence. We can see from one data: in the blockchain instry of Hurun 100 rich list in 2018, the richest person is Mr. Zhan ketuan, a partner of bitcontinental, a miner. In addition, according to the prospectus, bitcoin's net profit in the first half of the year was US $743 million, an increase of nearly eight times over the same period last year. Bitcoin once occupied more than 70% of the global market share of mining machinery, becoming the leader in the mining machinery instry. Not only mining machinery, bitmainland still occupies a near monopoly position in the mining pool (that is, a mode of cooperative mining): at present, the computing power of the top six mining pools in the world accounts for 79.2%
after the invention of China's first bitcoin miner, Jianan Yun, another miner chip research company, began to engage in the research of chips in the field of blockchain and artificial intelligence. In just a few years, it has also become an internationally famous chip enterprise
in fact, as early as 2012, the United States announced that it was going to sell a butterfly miner, but many people later thought it was a scam, because it took several years for the butterfly miner to go on sale, which also made the R & D of mining machines in other countries become very scared, and they were all scrambling for time, in a sense, Butterfly mining machine is also driving the prosperity of mining machine instry. So, in 2013, the mining machine has entered a season of contention, and a large number of ASIC mining machines have been put forward: or announced research and development, or announced pre-sale, or in the form of spot: cat roasting mining machine, pigeon mining machine, TMR mining machine, biter mining machine, Rand mining Bureau, little bee mining machine, Avalon original factory and various OEM, garden mining machine, Smart mining machine and so on... Maybe you haven't heard of these mining machines, because they are basically dead. Bitcontinental, Jianan Yun and Yibang have become mining machine giants< However, as a derivative instry under the prosperity of cryptocurrency market, the price of mining machinery is closely related to the cryptocurrency Market: in the bull market, the supply of mining machinery often falls short of demand, and it is common for miners to buy Mining machinery from "scalpers" at several times high prices. At this time, mining machinery manufacturers enter the dividend period. However, in a bear market, mining machinery manufacturers will also be adversely affected. As miners' enthusiasm for mining declines, some manufacturers have to rece the price of mining machinery to recover costs. For example, when bitcoin plummeted in March this year, a certain model of mining machine sold by Huaqiangbei was on sale at a price of 5000 yuan, and the price dropped from about 19000 yuan to
14000 yuan
[summary]
at this point, we can find that whether it is the project party, the exchange, the media, or the mining machinery, it can be said that it is a kind of "one-stop"

2. Bitcoin is a digital currency based on a specific algorithm. < blockquote >

bitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a kind of currency since ancient times. Bitcoin was born in 2009 and created by a person named Nakamoto. As the earliest digital currency, it was worthless at the beginning of creation. Until 2017, the highest transaction price of bitcoin exceeded 30000 RMB. The reasons why bitcoin became a valuable digital currency are as follows:

first of all, it is like gold, as a natural mineral, The total amount of bitcoin is limited. Bitcoin can not be over issued according to its own algorithm, so there will be no rapid devaluation of currency e to excessive currency issuance. The number of bitcoin is controlled to no more than 21 million e to the algorithm, so it can not be issued in large quantities, so its value is guaranteed

3. Yes, it has increased 45 times in half a month

4.

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

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

5.

The concept of bitcoin was founded by Nakamoto

On December 12, 2010, when bitcoin graally became a hot topic, he quietly left and disappeared from the Internet

As a descendant of samurai, Nakamoto was born in 1949 in Beppu, Japan. His mother, quanzi, was a Buddhist and brought him up in poverty

When his parents divorced in 1959, Nakamoto's mother remarried and immigrated to California with her three sons. Nakamoto and his stepfather don't get along well, but according to his younger brother Arthur, Nakamoto showed his talent in mathematics and science when he was very young, but also showed his "fickle and strange interest"

Nakamoto graated from Caltech, majoring in physics. Upon graation, he joined Hughes Aircraft and worked in defense and electronic communications. Later, Nakamoto worked for the U.S. military, and his experience was classified as a state secret. Now searching his files, his life is a blank

In 2008, in an e-mail group discussing information encryption on the Internet, he published an article outlining the basic framework of the bitcoin system. In 2009, he established an open source project for the system, officially announcing the birth of bitcoin. On December 12, 2010, when bitcoin graally became the climate, he quietly left and disappeared from the Internet

6.

Blockchain platforms include Ethereum, Asch and other underlying application development platforms

Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)

arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises

extended data

in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: public account book for all transactions

by using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently. The blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design is a source of inspiration for other applications

bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications

7. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.
