Mining 300mhash

1.

mining has been successful, a total of one equipment (CPU mining, 4-core bar), computing power: 12.75 khash / S (generally abbreviated as KH / s)
KH / S is very rare, so is MH / s; Now the more common are GH / s, th / s, pH / s. The conversion rate is about 1p = 1000t = 1000g = 1000m = 1000K

now the basic unit is GH / s, and several hundred g mining machines are very common

[bitcoin mining machine]

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world

2.

You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:

{rrrrrrr}

power consumption: 243w

< H2 > extended data:

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics

the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator

3. At present, the mining and purchasing of mining machines, including the later hosting, are basically carried out on ihash. In addition to high efficiency, they are mainly reliable.

4. If it works, it's a real cow.

5.

Hash algorithm maps any length of binary value to a fixed length of smaller binary value, which is called hash value. Hash value is a unique and compact numerical representation of a piece of data. If you hash a piece of plaintext and change only one letter of the paragraph, subsequent hashes will proce different values. It is computationally impossible to find two different inputs with the same hash value

message authentication code (MAC) hash function is usually used with digital signature to sign data, while message detection code (MDC) hash function is used for data integrity

the basic information of bitcoin network is as follows:

all digital currencies that need to be mined have hash values, such as Laite coin, Ruitai coin, doggy coin, Weimeng coin, Diandian coin, Yuanbao coin, etc< br />

6. Normally, nivdia Series graphics cards are all at this speed. If you want to increase the mining speed, you need to use ATI Series graphics cards

ATI 7950 can reach 300m

7. According to the calculation of the whole network computing power and difficulty, the number of coins proced in a day is fixed,

whole network computing power (estimation)
199947 gigahashes / s

this is the current computing power of 3600 coins proced per day divided by computing power 0. It's just 8000g last month. The price is rising too fast. The mining machine has been in mass proction

8. At 170mhash / s, the 24-hour output is only 0.1 bitcoin... I also turn.. Wow, there's this in it? I don't understand at all..

9. At 170mhash / s, the 24-hour output is only 0.1 bitcoin, 58.5 ~ ~ ~ let's calculate....

10. Let's take a look
