Bitcoin PC

1.

At present, the mining machines in the market are mainly divided into two categories, one is PC based mining machine, the other is professional mining machine based on ASIC chip

the general PC mining machine can be used as a home computer, but the CPU performance is weak and the power consumption is high. Professional mining machine based on ASIC chip can not be used as ordinary computer because it has no graphics card and does not support mainstream desktop operating system

extended data:

mining machine is one of the ways to obtain bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction

any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is just a garbage card like hd6770, can surpass the single graphics card of most users in terms of computing power

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there are considerable expenses in mining

in addition to the display card burning machine, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation. Although the performance may not be able to kill the display card in seconds, it is already quite strong. Moreover, because their power consumption is far lower than that of the display card, it is easier to form scale and the electricity cost is also lower, It is difficult to compete with these excavators. And this kind of machine will be more expensive

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

First of all, if the home computer is used to calculate bitcoin, even if the configuration is high, it will take several days to dozens of days. It may come out with a string of effective bitcoin (that is, bitcoin), and then it can be traded through the market of circulating bitcoin

special bit code operation requires a lot of graphics resources, so there are so-called mining machines, as shown in the figure below

this is a miner, which is specially used for mining. Such a miner may not be able to dig a bitcoin a day; The price of a mining machine is at least about 20000 RMB, and mining is a very power consuming project. All the graphics cards are running with full load, and the electricity charge will be very high

so don't blindly follow this kind of thing, it's not something that ordinary people can dig up with their home computers

4.

The steps are as follows:

1. Add a mine pool. 2. Download the software. 3. Start digging after setting

however, it is suggested that the building owner give up and dig bitcoin mainly depends on the GPU, that is, the processing chip on the graphics card. The home computer integrated graphics card can't be g at all. If the independent graphics card is NVIDIA chip, it's basically useless, because the most computing power is 160m / s

according to the income ratio, the calculation power of the machine is less than 8g / S (8192m / s), even the electricity fee is not enough, so it's meaningless to dig with a home computer for more than ten yuan a month. If you really want to dig, you should buy a mining machine

5. Talk nonsense upstairs, attack Gao to pull hatred? Is space attack very high? Pulling hatred is a skill that can generate a certain amount of hatred. It's not that the attack is high enough to cause hatred, but the attack is low enough to cause stars to shatter. But it's just that if you don't understand the skill of pulling hatred, don't talk nonsense.
landlord, level 60, if you have enough money, you can get into a set of better equipment The attack is improved as much as possible. If you don't have money, you can dig the mines and the pearls. If you do a good job in making money, it's not so easy to die. Besides, Yunlu's defense is low and there's little blood, so it's easy to die. But when the equipment goes up, it's very powerful with good operation

6. < UL >

if you want to mine through the new route generation 2 or 3, you need to connect an external mobile hard disk with a capacity of at least 64GB, and the higher the capacity is, the faster the interface speed is, and the easier it is to generate high revenue

7. Bitcoin is a kind of virtual currency. To put it bluntly, it is to use the computing performance of computer to do coolie for large servers, and the cost saved will be shared with you. However, bitcoin is not cost-effective, and personal computers are not suitable for mining. The reasons are as follows:

1. The calculation is mainly done by GPU, while the GPU of ordinary computers is not very powerful, which directly leads to low mining efficiency, and even the electricity bill can not be recovered

2. Because it is used to exchange data on the network, not only the performance of the computer should be good enough, but also the network bandwidth and quality should be higher. If you are asked to build a telecom 100 MB broadband before, I wonder if you are still so interested

3. GPU will generate a lot of heat ring calculation. If it is not handled properly or the original radiator is very dirty, it may burn the GPU or computer, and the gain will not be worth the loss

4. The other is the impact of the environment. Let's not say where bitcoin is going to go, let's say that the current exchange rate is seriously declining and there is no money to make before. Professional mines are even processing equipment. It's obviously unreasonable to go mining at this time

of course, if the computer is not yours, you don't have to pay for the electricity, and broadband doesn't need money, then you can try it....

8. 1. Bitcoin file format
bitcoin is stored in a program or client and controlled by private key
2. Bitcoin GB or MB or KB

after the complete bitcoin client is synchronized, it has a volume of 23g at present. Because of its large size, there are currently online wallets or lightweight clients to choose from

3. Whether the size of each bitcoin is the same
Yes
