Virtual currency is available every 5 minutes

Bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours

China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin

bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it

instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan

in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction

assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours

now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second

at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements

in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

Background: the financial application of blockchain technology brings high investment value

2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles

1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:

in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost

2. Why can blockchain solve the above pain points:

blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs

3. The application of blockchain technology in the financial field mainly includes the following aspects:

① digital currency

among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits

Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost

③ digital bills

④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost

The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology

4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points

in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it

Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall)

In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreement

bitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain

based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network

2. Master node network

the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

Figure 6: Mining reward model

5. Bitcoin generates a block in an average of 10 minutes, not evenly distributed
a block is a record in the block chain, which contains and confirms the transactions to be processed. On average, a new block containing transactions is added to the block chain by mining every 10 minutes
Puyin, Laite coin, doggy coin and Ruibo coin all have their own blocks, and the transaction information will be recorded on the blockchain.

In the environment of virtual currency trading, the fluctuation of the currency market is weaker day by day. According to Du Dongfeng, an analyst of the medium and long-term currency Commission network, the medium and long-term cycle should be a downward trend of inter district fluctuation. The price fluctuation in the range of 8000-4500 in this year is more likely, and the currency market may continue to fluctuate for a long time. The intraday fluctuation range may shrink again, and the intraday fluctuation range within $100 may become a high probability event! The weakening of the mainstream currency range will undoubtedly affect the profit margin and lengthen the trading time of medium and long-term trading. For investors, the rate of return and capital occupancy will be greatly reced! Therefore, the general virtual currency trading or short-term or into a virtual currency position trading short-term trading trough. But the popularity of virtual currency trading is still on, so users of virtual currency trading are likely to find a neutral proct in the derivatives of virtual currency trading to replace the vacancy of virtual currency position trading. Du Dongfeng, an analyst at cnki.com, believes that short-term trading of virtual currency will be the best choice for the next round of virtual currency fever

what is virtual currency short-term trading

There is no doubt that the short-term transaction of virtual currency can be understood literally as the short-term transaction mode of virtual currency. The short cycle trading mode of virtual currency is a new way to play in the virtual currency market, and it is also a popular derivative proct of virtual currency trading in this year. Its trading mode can be understood as: fixed investment amount to judge the market fluctuation direction of fixed time cycle. Transaction amount and fixed transaction profit and loss can be predicted. It means that transaction costs, gains and losses are controllable

for example: when trading on the short-term trading platform of virtual currency, Xiaoge found that the short-term fluctuation of bitcoin was in a small downward trend at that time (the price of bitcoin was 6666.66 at that time), and predicted that the market would start to fall in five minutes. He made a five minute drop of 100usdt bitcoin at this price, and when the closing price of bitcoin was lower than or equal to 6666.65 five minutes later, Then I can get 180 usdt of income (including 100 usdt of transaction principal). If the closing price is higher than 6666.67 after five minutes, the single transaction will be at a loss

as shown in the figure:

generally, the lowest transaction is from 5usdt, and a single transaction may reach 1000usdt or higher. The transaction time cycle is generally 1, 2, 5, 15, 30 and 60 minutes, and the rate of return is also determined according to the time cycle

I think if we want to keep up with the upsurge of virtual currency, we can pay attention to the short-term transaction of virtual currency! Because in any investment, investors at the forefront are the most profitable and still belong to the first group to eat crabs! More related consulting money commission network, money commission network is not only to provide you with a virtual currency trading platform, but also a virtual currency instry leader! The short-term transaction of virtual currency is undoubtedly the derivative proct of virtual currency transaction, which accelerates the virtual currency transaction to the super short-term stage

As we approach the end of the year, when we plan to sprint for the goal of the end of the year, earn more bonus and prepare to release ourselves in the Spring Festival, don't forget that the fraudsters also have such a plan. At this time, the tide of shopping on double 12 and new year's day comes one after another, and people working outside are also busy booking tickets and air tickets for the Spring Festival, which provides opportunities for fraudsters. Here, liewang, the first online fraud information reporting platform linked by the police and the people in China, makes an inventory of the new trends of online fraud in 2017. Can you see through all these scams

trend 1: mobile payment has become the mainstream, beware of two-dimensional code trap

mobile payment has greatly facilitated people's life and made people travel easily. However, there are many criminals who use the way of scanning two-dimensional code to carry out fraud, which is impossible to prevent. For example, on bike sharing, a fake QR code is used to cover the regular QR code, and the avatar is set as the official icon of bike sharing to cheat users to pay or recharge; Next to the store's two-dimensional code, there are words full of temptation, such as "scan code to grab red packets", "scan code discount", etc., to lure users to scan the code, and then obtain user information or directly guide users to transfer money. There are even criminals who the illegal parking notice posted on the car by traffic police. The fake ticket is attached with a payment QR code to lure the car owner to scan the code to pay a "fine"

trend 2: fake businesses want to refund. Users should be careful of being" loaned online "

generally, people think that their bank card balance is small, even if they encounter swindlers, it doesn't matter. However, according to the report cases received by liewang platform, In the common refund fraud in 2017, fraudsters use mobile phones to receive SMS verification code to lure victims into Internet micro loan business, and finally transfer the loan to the swindler's account. This kind of fraud often involves a high amount of money and brings serious property losses to users

trend 3: mobile phones also contain extortion virus, and the payment method is more" people-friendly "

mobile phone extortion software has become a common tool for criminals to seek benefits e to its low proction cost and fast cash flow. At present, there are different forms of blackmail software in the mobile application market. Different from the blackmail software in the computer, bitcoin is needed to pay for it. The payment form in the mobile blackmail software is more "people-friendly"

a batch of blackmail software captured in 2017 attached wechat two-dimensional code information to the blackmail interface, and prompted the winner to directly scan the two-dimensional code for payment by wechat, which will automatically unlock after successful payment, and the user will automatically enter the transfer interface after scanning the code. However, through technical analysis, this kind of blackmail software does not have any code related to wechat transfer. The so-called "scan payment, automatically unlock" is actually a fraud, even if the user transfers, it will not automatically unlock

trend 4: fake customer service requests to provide payment code and swipe only by numbers

because code scanning payment is simple and convenient, in 2016, many fraudsters took a screenshot of the two-dimensional code to swipe. But in 2017, as payment companies added anti fraud tips or confidentiality settings in the process of payment QR code screenshots, swindlers immediately thought of countermeasures and swindled the numbers under the payment code, forming a new instrial chain

criminals often disguise themselves as merchants customer service, requiring users to provide figures such as Alipay, WeChat and other payment bar codes, and then, on the grounds of digital failure, require users to refresh the numbers and send them several times to achieve the purpose of stealing. p>

trend 5: download the specified software, but the account password is shared by cloud disk

users' privacy information can be stolen without using phishing websites and Trojan horse software. This year, swindlers have come up with new tricks: as long as the victims' trust is obtained, they can download cloud disk, synchronization software and other procts, log in to the account designated by the swindler to upload files and synchronize, and then they can easily get information. What's more, if the user synchronizes the SMS verification code at any time, the swindler can easily steal the funds in the bank card

fraudsters often disguise themselves as e-commerce, suppliers and other customer services, requiring users to download some cloud disk synchronization software, and then provide the specified account password for users to log in. At this time, if the user logs in and synchronizes the personal account, password and other information on the software according to the swindler's instructions, the funds on the account will be transferred quietly

trend 6: new phishing websites on mobile terminals are more covert and easy to be recruited

as security manufacturers increase their efforts to crack down on phishing websites, phishing website makers also strengthen their covert means, spread links by using proct sharing functions such as short URL, cloud disk service, browser and social tools, and finally jump through the URL, Guide users to phishing sites to launch online fraud

trend 7: indemnity should be paid in intimate way. Be careful with this kind of fraud SMS

as early as 2013, 360 company discovered a high-risk fraud binding the victim's online banking account. In recent years, with the use of mobile payment becoming more and more popular, In 2017, there was a similar kind of fraud, which used a payment platform to bind accounts and swipe victims' accounts

in May 2017, Mr. Di received a flight delay text message sent in the name of the airline, with flight information and customer service phone number attached in the text message, and said that Mr. Di could get 300 yuan of delay compensation. Fake customer service in the phone to guide Mr. Di refund operation, and provide the enterprise account, but also ask Mr. Di to open intimate payment function. However, after Mr. Di opened, he found that he had two dections, and realized that Mr. Di was cheated and immediately called the police

trend 8: investment in the circle of friends? Do not gambler psychology

in everyone's wechat group or circle of friends, there are often many activities or proct recommendations under the banner of discount. Not long ago, Mr. Wang saw a WeChat official account named "double half price win" in WeChat group chat. Mr. Wang then identified the official account as having an enterprise certification and believed that the platform had high credibility. p>

Mr. Wang invested a small amount in the early stage, and found that there was a certain income every day, so he subsequently invested in batches, but graally began to lose money“ He wants to invest more in order to earn back the capital. As a result, when contacting customer service again, he found that the other party had blackmailed him. Only then did he realize that he had been cheated and that the money he had invested had gone to nothing

trend 9: identity impersonation has a new pattern, be careful that "friends" are high imitations

in the past, online fraud of identity impersonation often occurred on QQ, wechat and other social platforms, but this year, swindlers shifted their focus to microblog. The swindler specially studies the social habits of the victims, such as the relationship between microblog staff and chat content, and then changes their avatars and nicknames to create high imitation numbers. Because most of the fake users are abroad, it is difficult for their microblog friends to distinguish the true from the false in time

trend 10: the combination of various means makes it impossible to prevent the" ghost "fraud.

in March 2017, 360 assisted the Shenzhen police in successfully cracking down the" midnight ghost "Telecom fraud Gang, which the police identified as an illegal trade instry chain relying on personal information, It is a high-tech, high intelligence, cross platform, remote-control new type of telecom network fraud crime that combines mobile cloud service, operator's deputy number service and Internet financial service. And this kind of stealing brush mainly uses different services of various platform service providers. A single service does not have the security risk of stealing brush, but it is combined to form stealing brush. In order to make it difficult for the victims to detect, the criminals choose to commit crimes late at night. The whole process does not need to have any contact with the victims, and the victims do not need to reply to any SMS, so prevention is very difficult

from the above ten cases, the current situation of network fraud is still not optimistic. The anti fraud experts of liewang platform hereby remind the netizens that the new year is approaching, the fraudsters are highly active, and all kinds of fraud means emerge in endlessly. At this time, we need to improve the anti fraud awareness, so that the fraudsters have no chance to take advantage of it

net hunting platform is jointly launched by Beijing Public Security Bureau and 360. It is an innovative platform to crack down on Internet fraud through Internet platform and Internet technology. Up to now, liewang platform has established contact with public security organs in more than 300 regions of the country, helped to detect more than 100 major Internet fraud cases, involving 170 million yuan, and knocked down more than 10 large-scale fraud gangs with strict organization and clear division of labor. Internet users can report malicious programs, malicious web addresses, fraulent phone calls, etc. to 360 Internet security center through the platform. Every piece of information reported by Internet users will be included in the big data of liewang platform, providing effective clues for the police to solve cases

8. Wen Yuan is a liar! Before Wen Yuan, the character was Han Ze, all pseudonyms! Before they cheated us to buy mythical currency, now the dog cheated us to buy bitcoin on their own fake platform. The data on the platform will be delayed compared with the external disk. In this way, they can control long or short. If they ask you to reverse it, you will be closed, and you will not know how to die! These are all pig plates (three months of harvesting victims, the first month has given lectures for Mingbo's favor, the second month deliberately said that stocks are not easy to do, how good digital currency bitcoin is, and then told you that their own fake digital currency has prospects, deliberately took out their own fake account to cheat people in, the third month after harvesting, the swindler lost contact, and the swindler retreated completely), We have been cheated in the case of 10 people arrested, but this fake article is far from continuing to be a shooter, cheating! Now, there is a group called "competing for the best" and an organization called "JingWuMen". They have a clear division of labor among cheaters (lecturing, entrusting, collecting money, opening an account, assistant, etc.) and really ignore the national law! Now Wenyuan has an account holder named Liu Qian, Zhang Jia (pseudonym) and others. I suggest you buy ukgr digital currency! Lower case (ukgr) don't buy it. The platforms are all made by themselves. You can control the rise and fall at any time. If it's not a real platform, you can close the platform at any time! It's the same as the myth coin recommended by Han Ze (the same person in Wenyuan) before. It's all fake! At present, we have lost hundreds of millions! The whole country has also set up an ad hoc group to solve this case. I hope that more people who have been cheated can read this article, so that this group of swindlers can be less successful! Finally! The most important word! Ask the local police before investing, because they will explain to you that this is a fraud! It's a fraud!

It can not be said to be a fraud, but there are certain risks, because digital gold currency is a form of physical currency, and its deposits are measured in gold rather than legal currency. Therefore, the purchasing power fluctuation of digital gold currency is related to the gold price. If the price of gold goes up, it becomes more valuable. If the price of gold goes down, it loses value

since there is no specific financial regulation to regulate digital gold money suppliers, they operate in a self-regulation way. Digital gold money suppliers are not banks, so banking regulations are not applicable

extended data

to explore the connotation of digital currency, we must clarify some concepts of model lake. For example, is it legal digital currency dominated by the central bank or illegal private fixed digital currency; Encryption of digital currency or electronic currency; Is it "selling dog meat with sheep's head"; "Bad money"

new technology does make the conceptual boundary of money more blurred. Theoretically speaking, the new monetary economics points out the possibility of the disappearance of money, that is, legal paper money is no longer the only medium of transaction, and is eventually replaced by financial assets issued by the private sector that generate monetary income

in reality, although the status of fiat money is still unshakable, there have been various local scenes of private money in history, such as the universal warra system in Germany in the 1920s. Now the digital currency with the characteristics of decentralization makes the challenge of private currency increasingly prominent< br />
