Recently, someone at the entrance of the Netease headquarters had pulled a banner and was duped by Netease's one dollar purchase. As early as July of this year, people had already pulled banners in front of the Netease Tower and claimed that another similar product of “Netease†had “one dollar won the treasure†and killed his family. It is reported that "Netease One Dollar Winner" is produced by NetEase's mailbox division and the development team is located in Guangzhou. The "Netease One Dollar Purchase" is developed by the Netease Beijing lottery team.
In addition to NetEase, there are still one yuan cloud purchase, one dollar crowdfunding and other products on the market.
 What is a dollar purchase?The logic of a single-buy product is very simple: Assume that a product is a mobile phone worth 2000 yuan, and the yuan mall will price this product at 2,500 yuan, which is 500 yuan more than the usual market price. Then, the 2,500-yuan cell phone was split into 2,500 copies, and 1 yuan was a unit. After 2,500 copies were sold, the one-person purchase platform took the lucky person and the cell phone returned to him. Of course, if users increase the probability of winning, they can also place more money. For example, if you bet 1,250 yuan, there is a 50% chance of winning.
The return rate of “one dollar purchase†is higher than that of ordinary lottery tickets. According to the return prize rate, in theory, the more purchases, the closer the user's investment and platform price for winning prizes will be, and that the platform will only earn a portion where the commodity’s price exceeds the market price. Why do so many people respond to invest a lot of money, but the benefits are few. Of course, part of the reason is bad luck, but it does not rule out that some platforms have dark box operations.
 How to black box operationInformed sources said that some of the one-person shopping platforms claimed that the winning numbers were directly generated by certain official lottery lottery results issued by the Chinese government, and then calculated the winning numbers through relevant formulas. The implication is that the generation of winning numbers introduces third-party authoritative data and eliminates the possibility of black-box operations on the platform side. However, after a thorough understanding, it is found that the actual situation is not the case.
Entering the “One Dollar Purchase Template†keyword on Taobao.com, we found that there are a lot of information on selling the source code or off-the-shelf platform for building a website. Each product has a maximum of a few thousand dollars. According to sources, the source code system publicly sold at Taobao has a cheating function that assigns a winning member number. The updated version is based on the official winning number of the time and lottery as a draft certificate, making the lottery more realistic. However, the introduction of the lottery lottery program is in fact an upgraded version of the cheating system. It can not only operate the winning number privately, but also use the lottery lottery to create a disguise.
CCTV had previously revealed that many "One Dollar Purchase" platforms did not supervise the process of the lottery, and they could even control the winners and the lottery progress in the background. Businesses can even add virtual robots in the background to participate in the lottery process. Through human manipulation, these robots can win prizes:
Data analysis expert Shi Wenxiang Lei Feng network (search "Lei Feng network" public number attention) describes the current market on the Indiana class lottery algorithm, and lists the corresponding products of each algorithm:
The basic approach of the algorithm is to use a number N to add 1 to the commodity's selling price. For example, a commodity with a price of 100 yuan is used. The remainder after N is used for 100 is 0-99, and the range after adding 1 is 1-100. Just correspond to the sold 100 numbers (whether adding 1 is not important, someone asked the number to be worse 1 is not the reason for this plus 1, this is just to take over later correspondence). Whether or not it is fair depends on the composition of this number N and whether the platform is maneuverable. At present, the number N of the platform generally uses the A+B mode. Each used AB is different. A is provided by the platform itself. For example, the number of purchase records at the last time is added. In theory, the platform can be controlled. And whether the whole value N is controllable depends on the number B:
Only the number A:
This is the most direct falsification. A is how many platforms have the final say, resulting in controllable winning results. Simply speaking, if you calculate the gold ingot value of RMB 50,000 according to the final purchase record, he only needs to change the record of the last purchase time. It is not you winning, and the last purchase time is calculated in milliseconds. . On behalf of the product: One cloud X, Netease 1 yuan X, win X master.
The number B is fixed:
The so-called fixed value is that the number B uses the price of the product itself to do B or give you a fixed number. This method is the same principle as without B. Because B is known, your medium and low are determined by the A given by the platform. On behalf of the product: nest X fold, one dollar grab X, all the people win X.
Number B is not the latest lottery ticket:
This comparison is puzzling, and it looks like there is no problem, but when you find out that the prize is sold out, the value B selected for the prize is a lottery ticket that has already been opened. This is the same as the first two, belonging to the category known as the value B. Representative product: Take X.
The number A is not published in advance but is given together with B:
This method selected the latest lottery lottery, but did not tell you what A was when you were waiting for the lottery. It was the last time you told AB all. At the time of the lottery, he knew that B had changed A (before A had no publicity, how many can be changed now). The interface of these products is basically the same, presumably sold by the same source code. On behalf of the product: red packets win X, every day cloud X, every day take X.
The number A is given in advance, and the value B is the latest lottery ticket that was not known at the time of A:
When such products are sold and waiting for the lottery, the value A is publicized first, and the lottery ticket for which value B is selected is publicized, and the lottery official website is still waiting for the lottery. Since the value B is indeterminate, the value A has been publicized and the final result platform cannot be controlled. Such products are reliable. On behalf of the product: Walnut X treasure, a dollar X treasure.
 Is it crowdfunding or betting?
At present, many “one dollar purchase†platforms in the market are all in the name of “crowdfundingâ€. But whether it is equity crowdfunding or debt crowdfunding, before the purchaser makes a purchase decision, he has a clear expectation of the future outcome. The "one-dollar purchase" model is not an equity or debt, but an opportunity to win. In essence, these platforms actually belong to the sales opportunity. The country had previously stopped similar online sales. One dollar purchase is, to some extent, disguised betting.
Why is there no control?
According to sources, the administrative departments of industry and commerce, lottery, etc. stated that “one dollar purchase†and “one yuan grabbing treasure†do not fall within their scope of supervision. Even though the lottery administration can theoretically manage it, it has no enforcement power.
Shi Wen mentioned that there are too many platforms on the market where the algorithm is not strict. One dollar purchase itself is not a scourge, but everyone needs to understand the essence and then participate.
