(Text / high-tech LED reporter) Recently, Gaogong LED reporter learned from the rail transit construction and other departments that the LED display of the Wuhan Light Rail Zongguan Station, which has received much attention, has been successfully screened. Bitcoin mining machines are one way to obtain bitcoins. Bitcoin is an online virtual currency created by open-source peer-to-peer software. Instead of being issued by a specific currency institution, and produced by the massive computation of a specific algorithm, the Bitcoin economy uses a distributed database of nodes throughout the P2P network to identify and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin by producing a large number of coins.
Any computer can become a mining machine, but the returns will be low, and it may not mine a single bitcoin in a decade. Many companies have developed specialized Bitcoin mining machines with special mining chips that are tens or hundreds of times faster than normal computers.

It is understood that heavy advertising equipment has never been set up on special bridges such as domestic light rails and highway interchanges, because once the weight exceeds the limit, serious safety hazards may occur. At the same time, the flow of people near the light rail is very large. Its brightness and stability are not only related to the safety of citizens, but also to the safety of light rail and subway. Therefore, the approval of such advertising space and its media by the rail transit and city departments is extremely Be cautious and strict.
However, this 500-square-meter LED display has a solid "Anjia" in Wuhan Light Rail Zongguan Station. What advantages have it passed for approval? What is the reason for this LED big screen to dominate in this special complex environment? The reporter visited the LED display manufacturer "Dongguan Xinghuang Electronic Technology Co., Ltd." Chairman Luo Ge to accept our exclusive interview with relevant questions. 
Reporter: It is understood that the LED display screen of the Wuhan Light Rail Zongguan Pass is manufactured by your company. Please tell us about this display simply.
Mr. Luo: The LED display project was successfully auctioned and independently produced by our company. To be precise, it is called “two-sided LED displayâ€, which is an LED shaped screen. It is a function of adding a three-sided flip-up picture on the basis of the LED display screen, and the two are optimized and combined to enhance strengths and avoid weaknesses. During the day, it is used on three sides, so that two of them are alternately flipped. The power consumption is only 90 watts per hour and only the motor is running. This avoids the rigid and flattening of traditional print ads and saves energy. It solves the ordinary electronic display. The electricity consumption during the day is large, and the problem of insufficient effect is displayed under direct sunlight. In the evening, it turns out the third side and becomes a full-color LED display, which makes the effect and expression more diversified. It does not need air conditioning and manual duty. The power consumption per square meter is only 90 watts, which is the traditional LED display. One of the points.
Reporter: It is said that light rail bridges are not allowed to set up heavy advertising equipment due to vibration and other reasons, and your company's LED display on both sides is not only reviewed by the city safety supervision bureau, city management and subway group, but also smoothly screened. You can share it with us. What about the relevant experience?
Mr. Luo: I think, using the term "good things and more grinding", the term is used to describe the current process. The display project has gone through numerous projects from the project to the tender, and has undergone countless bumps and sorrows, whether it is the construction of Wuhan Sigel Media or The bidders of us, all of us have only one wish, that is to ensure that it will operate safely, stably and efficiently in the future.
At the beginning, the construction party decided to enable the LED traditional large screen in the lot. Considering the particularity of its location, it organized a “several field†LED display feasibility discussion and expert review meeting, which was invited to include “Huazhong University of Science and Technology, Wuhanâ€. Dozens of experts and professors from the Polytechnic University, Hubei University of Technology, the Municipal Safety Supervision Bureau, China Railway Fourth Survey and Design Institute, Wuhan Advertising Association, as well as the Municipal Urban Management Bureau and the Rail Transit Management Office attended the review meeting and passed the fierce comparative argumentation and discussion. In the end, Xinghuang Technology's LED display on both sides was selected with many advantages such as low carbon, energy saving and light weight.
Reporter: Can General Luo introduce the focus of the argument at the meeting? What are the advantages of your company's LED display on both sides?
Mr. Luo: At the time, there were four main points of discussion. First, the weight of equipment, second, must be energy-saving and environmentally friendly, third, new technology and new materials, fourth, the need to beautify the city without light pollution and the landscaping of the city to play a icing on the cake.
As we all know, the train generates strong vibration during driving, and the vibration will pose a security threat to the advertising equipment on the bridge. Therefore, the weight and structure requirements of the advertising equipment on the light rail bridge are very high, because the light rail bridge is designed and built for the attachment. The load has a clear limit, while the traditional LED display screen body weight is generally above 40-60KG, while the double-sided LED display screen body is only 23KG per square, plus the structural weight is still much lower than the bridge's load margin.
Secondly, energy conservation and environmental protection. In recent years, with the shortage of power shortages and energy supply, high-energy LED large screens are faced with the choice of life and death in the shadow of electricity shortage, and the traditional LED display consumes more than 400-800 watts per square meter. In addition to the energy shortage, thousands of watts of air conditioners have become the target of public opinion. They have to endure high commercial electricity expenditures or let the electricity stop. After all, the "high" is not cold, and the traditional LED display is more energy-consuming. High, in the background of electricity shortage, electricity, power cuts, etc., it is inevitable to face the embarrassing situation of stop broadcasting. Taking Jindano's double-sided LED display as an example, compared with the energy consumption of the same area LED display in Shenzhen, it is also a 200-square-meter full-color display. Jindano's double-sided LED display saves electricity only once a year. More than 300,000 yuan, the operating cost is minimized. Because the double-sided LED display adopts energy-saving design, its power consumption is one-fifth of that of the traditional display and it does not need air-conditioning to dissipate heat. It only uses 90 watts per square meter of power consumption. In the debate, I won the championship.
The third is new technology and new materials. The LED display on both sides guarantees the best quality. Therefore, it introduces international advanced production technology and environmental protection and energy saving concept. Its equipment can guarantee normal use for 8-10 years. Jindano relies on LED display on both sides. Advanced manufacturing technology and strict quality inspection make it have a strong wind-resistant structure. Strong winds pass through the triangular prism gap and the patented louver backing plate to minimize the wind resistance and ensure the safety of its use. In the appearance of the screen, since the position is about 4.5 meters from the ground, when you stand on the ground, you can clearly see every detail on the display. As long as there is any flaw in the screen, it will be seen at all. Therefore, the operator and the city department The quality requirements of advertising equipment are almost harsh. After all, this is not only related to the image of advertisers, but also to the appearance of the city.
The fourth is to beautify the city and the pollution of the city. As a key city for the construction of two types in Central China, namely, resource-saving and environment-friendly, Wuhan has become the leading direction of urban construction. Therefore, the city appearance department requires two sides to turn the LED display and the city to share the same honor. The LED display really makes up the city outdoors, adding new colors to the harmonious beauty of the outdoors, making life more diverse. Nowadays, the advertisers are eye-catching and require the advertisement to “flash, light, jumpâ€, etc., so the current LED screen will be brighter and brighter, and the light pollution will become more and more serious. In addition to having a better visual effect, the high-brightness LED display also poses a serious safety hazard to urban traffic. When playing, its shining and beating images can easily interfere with drivers and pedestrians, resulting in traffic accidents. TV tower a traditional LED display is too shiny to cause traffic accidents, and the brightness of the double-sided LED display is tailored according to the visible distance and the scene environment, to minimize light pollution, the screen brightness is mild and there is no glare. This is also one of the main reasons for its selection. 
Bitcoin miners manage the Bitcoin network by solving the problem of proof-of-work mechanisms with a certain amount of work -- confirming transactions and preventing double payments. Because hashing is irreversible, finding the number of random adjustments required to match is difficult, requiring a trial-and-error process that can predict the total number of times. This is where the proof-of-work mechanism comes into play. When a node finds a solution that matches the requirement, it can broadcast its result to the whole network. Other nodes can then receive the newly solved data block and check whether it matches the rule. If the other nodes calculate the hash value and find that the requirement (the operation goal required by Bitcoin) is satisfied, then the data block is valid and the other nodes accept the data block.
