Application-Specific Integrated Circuit refers to an integrated circuit specifically designed to perform a specific computing task. It is very common to use ASIC for mining in the field of blockchain. This article will analyze the principle of ASIC mining and why it should be anti-ASIC.
For Bitcoin, mining has gone through four stages: CPU, GPU, FPGA and ASIC. GPU is naturally suitable for parallel simple operations, so the execution of SHA256 is much higher than the CPU. FPGA is a programmable hardware, because it has a certain degree of universality, so the unit price will be relatively expensive. ASIC has a large initial design investment, but the unit price will be cheaper after mass production. Therefore, if you can determine that the market size is relatively large, the use of ASIC technology will be the most cost-effective.
In a nutshell, mining is running complicated calculations in the search for a specific number. Whether it`s an ASIC miner or a GPU mining rig, mining hardware must run through many calculations before finding that number. In proof of work systems like Bitcoin, the first one to find that number gets a reward - at the time of writing, 12.5 Bitcoins worth around $96,850. That reward will fall to 6.25 Bitcoins in May 2020.

This is the basic principle of ASIC.
There are so many people and powerful computing systems trying to mine Bitcoin that miner groups form to find that number and share the profit. Even more, the faster your hardware, the more you earn. That`s why people who can afford it opt for ASIC miners because it gives them the greatest chance of earning cryptocurrency in exchange for their investment.
Each cryptocurrency has its own cryptographic hash algorithm, and ASIC miners are designed to mine using that specific algorithm. Bitcoin ASIC miners are actually designed to calculate the SHA-256 hash algorithm. In the case of Litecoin, it uses Scrypt. That means technically they could mine any other coin that`s based on the same algorithm, though typically, people who buy ASIC hardware designed for Bitcoin mine that specific digital currency.
The LED lighting design must take into account the luminous flux and the luminous flux, ie the illuminance, obtained from the illuminated or illuminated surface. The unit of measurement of luminous flux is Lumen. The unit of measurement for illuminance is Lux. The relationship between the two is 1 Lux = 1 Lumen/m2. Assuming a 10W LED spotlight, the total luminous flux emitted is 900 Lumens. If the 900 Lumens are all concentrated on a square meter of ground, the ground illumination is 900 Lux.
Commercial premises - commercial lighting is not only to meet the requirements of seeing the surrounding items, but also to stimulate consumers' desire to purchase and regulate consumer psychology. Bright foods such as bread, pizza, braised pork, barbecue, etc. can stimulate appetite, and after the long flowing water, the wallet is opened. So the bread cake shop, the fast food restaurant in Hamburg and the window of the restaurant should have an illumination of 1000 Lux or more. Jewelry, watches, and clothing stores must also have bright illumination to stimulate purchase. Precision factories, color printing, optical shops, 3C stores must also have 1000 Lux illumination.
Ordinary places - offices, classrooms, bookstores, supermarkets, coffee shops, fast food restaurants, factories, hospitals and other places, there must be 300-800 Lux, because too bright will be exciting, and easy to fatigue.
Event occasions - such as station airport, gym, building lobby, ward, corridor, stairwell, toilet 100-300 Lux, it is required to recognize faces and read newspaper texts at a long distance.
Leisure places - parks, parking lots, small streets, etc., where you don't have to read books and see objects, can be as low as 10-100 Lux.
Moderate illumination has a very significant impact on the competitiveness of the store. Nowadays, urbanization has led to high-rise buildings, and street shops are full of gold. In the face of fierce competition in expensive rents, convenience stores that are everywhere can stand out from the crowd. In addition to the products and services that everyone values, the LED lighting of the shops is done. It is also an effective means, and bright illumination can attract buyers to increase sales. Department stores cosmetics, jewelry and other key counters, illumination can be as high as 2000Lux, if the illumination is insufficient, it is difficult to attract attention and purchase desire, and LED lighting design can naturally focus the consumer's eyes through the contrast between bright and slightly dark areas Go where you need to maximize sales profits.
