Calculation power measurement of mining machine

1. If you buy a miner, you can go to digyi mining to have a look. I bought one a few days ago, which has high calculation power.

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
computing power: 22.4m
price of graphics card: 1999 yuan
quantity of eth g every 24 hours: 0.015
revenue generated every 24 hours: 24.48 yuan
expected payback time: 81.66 days

power consumption: 159w
computing power: 24.3m
price of graphics card: 1599 yuan Yuan
number of eth g every 24 hours: 0.017
revenue generated every 24 hours: 27.9 yuan
estimated payback time: 57.31 days

total power consumption: 171w
computing power: 24.4m
price: 1999 yuan
number of eth g every 24 hours: 0.017
revenue generated every 24 hours: 27.87 yuan
estimated payback time: 71.73 days

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. As the name suggests, the mine calculation card is a graphics card used for mining. More strictly speaking, it is a graphics card used for mining with high load for a long time. The graphics card used in mining usually works at full load 24 hours a day for several months. In this way, PCB and electronic components will accelerate aging, affecting the life of components. Not counting the rest time of the graphics card, even if we play the game for 8 hours a day, the life of the mine card is only one third of that of the normal graphics card. It can be said that the general life of the mine card is only a few months.

4. Now bitcoin's listing is blocked!!! You still dig, you go to the internet post bar, bitcoin bar, take a look

5. 0.03 bitcoin, about 17 yuan

6. In fact, bitcoin mining can not blindly pursue the size of computing power, but also depends on the overall performance of the miner. For example, the single-mode group of Avalon mining machine 2 will be able to recover its cost in about 40 days, but the 800g recovery time of Avalon mining machine 3 is far away, unless the currency price rises. If you are a retail investor, it is suggested that you buy mining machines with small calculation power and fast cost recovery time, which should be regarded as playing. If you have abundant funds and the ability to set up large-scale mining plants, it is suggested that you buy mining machines with high calculation power and high profits. Avalon's 2.3t miner is said to be coming soon.

7. Yes, it can be exchanged at the exchange.

A: first, block height does not refer to the capacity of the blockchain

Second, the connotation of block height

block height is the number of blocks linked to the main chain, that is, the number of blocks connected to the blockchain

Block height is the indicator of block

2. The block has two identifiers, one is the hash value of the block head, the other is the block height

3. The hash value of the block head is the number obtained by the second hash calculation of the block head by sha256 algorithm

The

block hash value can uniquely and explicitly identify a block, and any node can independently obtain the block hash value by simply hashing the block head

4. Block height refers to the position of the block in the blockchain

The

block height is not a unique identifier
