BTC crystal

1. 1. CPU is mainly optimized for serial instructions, while GPU is optimized for massively parallel operations
2. Modern multi-core CPU aims at instruction set parallelism (ILP) and task parallelism (TLP), while GPU is data parallelism (DLP)
3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications
4. CPU is a general-purpose operation. In short, it means brainless calculation and violent calculation. Whether it's 100 children sharing apples or simulating the earth, it can be decomposed into the most basic calculation of 1 + 1 = 2. GPU is specially designed to deal with high-order mathematical algorithms, such as calculating the relative positions of light source, object, viewpoint and shadow, which requires trigonometric functions to be piled up. The bitcoin digger uses SHA-256, a secure hash function invented by the US National Security Agency, which is generally used for password encryption and decryption. This algorithm can perform a large number of 32-bit integer right-rotate operations, which is very suitable for GPU which is good at large-scale concurrent computing and password cracking.

2. 1, because the task of BTC is a very simple calculation of decryption, it does not need too many instructions. In other words, the task of BTC only needs some specific transistors to be executed

2. The CPU is used to perform mining tasks. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle. The speed is relatively slow

3, in order to enhance the ability of displaying images, the graphics card saves a lot of transistors that have nothing to do with the display function, so the graphics card can only display pictures, but it is much faster than the CPU in the task of displaying pictures. BTC needs to perform the same task as the graphics card, so the mining of the graphics card is faster than the CPU, So a card is more suitable for mining.

3. When crystal 1 (0.2 * 0.2 * 0.1 cubic mm) was taken from the capillary, the cell parameters were determined, and then dried at 75 ° The crystal of Ni (c26h52n10)] 3 [BTC] 44h2o is immediately protected from moisture of air and epoxy resin, as well as X-ray structure determination (Fig. 2c, d). Unit cell parameters including cell volume changed significantly ring the transition from 1 to 2 (Table 1), but the crystallinity remained. 2, no actual change was observed in the two-dimensional layer (cavity size is 22.2 * 14.4 & aring; 2) 82 (2) & aring, Due to the significant inclination of the important pillars. In contrast, from an intuitive point of view, spongelike crystal dynamically reacts without breaking the single crystal. Blank Volume 2 is 27% of the total volume. When single crystal 2 is exposed to water vapor pyridine for 12 hours, or immersed in water pyridine mixture for 5 minutes, the recovery structure 1 proves that the X-ray powder diffraction pattern (see supporting data) is too small to determine the
X-ray structure.

4. First of all, the "mine" of mining is in fact a virtual currency such as "bitcoin" (this kind of virtual currency is actually a string of encrypted characters. Due to its very high scarcity, "relative value" is very high. The reason why we use "relative" is that for those who accept it, it is money. For those who do not accept it, it is a string of characters!)
mining is actually using a special customized computer to run a set of special algorithms to decrypt the encryption algorithm of virtual currency For example, this currency has a series of codes. People "guess" the code through the algorithm. If they guess all the codes correctly, they can get a complete virtual currency. If they guess one point correctly, they can get a part of it, such as "0.00035637 bitcoins". Yes, virtual currency can be divided. It is not possible to dig a complete bitcoin at one time. The bitcoin g is a string of characters.)
the reason for mining with graphics card is that the algorithm of decrypting bitcoin is actually very simple, which is not a high-level operation, but it has a lot of amount, and the graphics chip is more suitable for this than the CPU chip For example, 1 + 1 =? 2+2= This kind of algorithm seems simple to you, but if I tell you this kind of simple algorithm, there are 100 million in total?! Would you like to try to figure it out? I believe you can figure it out, but it's just a long time)
(CPU chips and graphics chips have a huge number of transistors, which are responsible for computing. The difference is that the transistors of CPU chips are divided into many parts, which can deal with all kinds of task instructions. When running simple operations, only a part of the transistors are working, The others are on standby, because other transistors are not responsible for this task. They can calculate, even if they are relatively slow, but they will still consume the same power, resulting in a low cost-effectiveness ratio.
(graphics chips are different. In fact, most of their work is "crazy rendering triangles". What's a crazy method? Render 1 billion triangles in one second!!! This work is relatively simple, but the amount is very large, and there is a high requirement for the speed of "rendering", so the graphics chip can make its transistors all move when it is designed, so as to achieve the purpose of "rendering" more triangles in the shortest time! This happens to be very similar to the process of decrypting bitcoin, so most of them use graphics cards to mine. This doesn't mean that CPU can't mine. People can mine with their heads. Do you believe it? It's just very slow, and the value of the bitcoin is not enough to pay for your electricity and meals)
mining can't "lie down and make money", because a qualified miner's price ranges from tens of thousands to hundreds of thousands according to its computing power. Because it consumes a lot of electricity, the cost of mining is not only to buy a miner, but also to include the electricity! Moreover, the mining machine needs good heat dissipation and daily maintenance to extend the life of the hardware as much as possible, so if you dig the mine, you will not have much leisure. In addition, the number of virtual currencies is limited, it is more and more difficult to dig, and the stability of the value is poor. Maybe you invest 10 million yuan to build a mine, and a wave of collapse will occur. You have been frozen for 10 million minutes

5. There are several aspects: 1; 2. Look at the trading volume; 3. To see if you have issued your own currency, the security of basically meeting these three conditions is relatively high. I have recommended the okex trading platform for another six or seven years.

Mining graphics card is faster than CPU, professional mining machine is faster than graphics card because: BTC task is a very simple decryption calculation, does not need too many instructions

That is to say, the task of BTC only needs some specific transistors

the CPU is used to carry out the mining task. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle

7. Because the task of BTC is a simple calculation of decryption, it doesn't need too many instructions. In other words, the task of BTC only needs some specific transistors

the CPU is used to perform the mining task. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle. The speed is slow and normal.
