Is virtual currency just a computer

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

2.

Some new virtual digital coins can be mined by computer, such as eth, Zec, Monroe, XRB, etc

because the whole network computing power required by this kind of token is not high, the probability of hash collision of the computing power of personal computer can find out the answer in a short time, so as to obtain the block reward. However, this kind of token generally has little value, or has no high risk, so it doesn't mean much

mining risk:

1. Electricity charge:

to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge 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

2. Hardware expenditure:

mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and mining has a considerable expenditure

in addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation, and the computing power is quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the power cost is also lower. It is difficult for single chip display to compete with these mining machines, This kind of machine costs more

3. Currency security:

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

4. System risk:

system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income

however, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners

Virtual currency wallets and local wallets are wallets specially used to store virtual currency

difference: local wallets are installed on their own computers or mobile phones, while online wallets encrypt the private key and put it on the server

personal computers may be implanted with Trojans; The wallet server also has the risk of being attacked by hackers, and the encrypted private key is cracked. Server security is better than personal computers, but it is easier to attract hackers' attention

< H2 > extended data:

virtual currency Wallet:

there are three main types: Online wallet, client wallet (mobile client, computer client) and hard wallet

1. Online Wallet: it refers to the operation of virtual currency relative to wallet by users in the form of network; The main form is website, which users can visit through computer and mobile phone

2. Client Wallet: it is an installation software, which needs to be downloaded to the computer or mobile phone, and can only be used after installation; This is the type of mobile app wallet that I just mentioned

3. Hard Wallet: it is similar to the wallet in the form of U disk, which is a real type of wallet

local Wallet:

the English name of local wallet is local wallet. Local wallet is to store private key and transaction data in local terminal, such as computer, mobile phone or other local devices; It refers to the storage location of the key, and its concept is independent of online wallet and offline wallet

the English name of local wallet is local wallet. It is one of the terms related to bitcoin wallet in blockchain. Local wallet is to store private key and transaction data in local terminal, such as computer, mobile phone or other local devices; Local wallet refers to the storage location of key, which is independent of online wallet and offline wallet

the local wallet is installed on your own computer or mobile phone, while the online wallet is encrypted and put on the server. Personal computers may be implanted with Trojans. Hackers may steal your wallet files and record your wallet password; The wallet server may also be attacked by hackers, and the encrypted private key may be cracked. Server security protection is better than personal computers, but it is also easier to attract hackers' attention. In terms of security, I think these two types of wallets are similar

to enhance the security of local wallet and online wallet, it's better to set a more complex password, and don't forget it. Both local wallet and online wallet are easy to use and easy to use. Because online wallet is not limited by clients, it is easier to use than local wallet. Bitcoin core, Bitai wallet and bitpai wallet all belong to this category

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

Bitcoin is actually a useless string of numbers, but it is recognized as useful, just like diamonds, antiques, calligraphy and paintings, game skin and so on. They can't be eaten or used, but we will recognize their value

"mining" just allows more people to participate in the construction of blockchain network. Is it really good that so many electricity charges are used to "calculate" a series of virtual values? Bitcoin is not a hedge. The price of bitcoin fluctuates greatly. Speculation on bitcoin may become rich overnight or become poor overnight. Bitcoin is not as safe as it claims. In 2014, the world's largest bitcoin trading website, mtgox, was hacked and went bankrupt, and the $467 million worth of bitcoin evaporated instantly. Criminals use it to launder money, evade taxes and so on. It is also quite difficult for the government to investigate. The above personal opinions are welcome to be criticized and corrected. Agree with me, please click like before you go, thank you! Like me, please pay attention to me, thank you again

6. ==It's not that CPU can dig, but the efficiency is lower than that of graphics card, so now we use graphics card as mining machine, because a motherboard can carry up to 6 graphics cards, while motherboard can carry Dual CPU or four CPU at most, and the efficiency and cost can't catch up with graphics card at all

7. The generation process of bitcoin is similar to solving an equation, but this equation may have many groups of solutions, and what we need is the only one with a very special solution. The generation process of this solution can be obtained through a complex algorithm, and the result is a series of 64 bit codes, similar to the number on the RMB
for the mining method, you need to register on the bitcoin website, download special tools, install them according to the usage of the tools and fill in a series of data, and then you can mine. In fact, the process of mining is the process of computing in computer kernel. The time of solving process depends on the ability of computer.
