Introduction of bitcoin mining machine and pumpkin machine
bitcoin mining machine is a kind of 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
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
The bitcoin mining machine downloads the mining software and then runs a specific algorithm to get the corresponding bitcoin after communicating with the remote server, so as to obtain the bitcoin
any computer can become a mining machine, but the benefit will be relatively low, and it may not be able to dig a bitcoin in ten years. Many companies have developed professional bitcoin mining machines, which are equipped with special mining chips, and their computing speed is tens or hundreds of times higher than that of ordinary computers
bitcoin miners can neither increase their rewards by cheating, nor deal with the fraulent transactions that destroy the bitcoin network, because all bitcoin nodes will reject the blocks containing invalid data that violate the bitcoin protocol rules. Therefore, even if not all bitcoin miners can be trusted, the bitcoin network is still secure
extended data:
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network
this process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary
anyone can run software on specialized hardware and become a bitcoin miner. Mining software monitors transaction broadcast through P2P network and performs appropriate tasks to process and confirm these transactions. Bitcoin miners can earn transaction fees paid by users to speed up transaction processing and additional bitcoin issued according to fixed formula
Hello,
bitcoin miner is mainly composed of graphics card and computing chip
hardware expenditure
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users. 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. Taking into account the hardware price and other costs, there is a considerable expenditure in mining
Bitcoin mining machine is one of the ways to obtain bitcoin . Bitcoin is a kind of network virtual currency proced by open source P2P software
it doesn't rely on the issuance of specific monetary institutions, and it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
any computer can become a mining machine, but the benefit will be relatively low, and it may not be able to dig a bitcoin in ten years. Many companies have developed professional bitcoin mining machines, which are equipped with special mining chips, and their computing speed is tens or hundreds of times higher than that of ordinary computers
extended data:
in terms of revenue, the issue and transaction of bitcoin are realized through mining, which is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block
the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins. In addition to the block award, the miner will receive a handling fee for all transactions within the block
The price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan. From 2011 to 2013, the high configuration bitcoin "mining machine" increased from 10000 yuan to 300000 yuan, but its performance is much better than before. According to instry insiders, the old machine can only dig 1 bitcoin in 100 days, but now (2013) machine can dig 3.5 bitcoins in 100 days
according to the miner information published by the domestic assembly team, a miner with the lowest configuration at the price of 3000 yuan can be returned in more than 30 days according to the bitcoin mining speed. The machine with mining speed of 10G / s can dig about 0.03 bitcoins 24 hours a day, while the machine with mining speed of 13g / s can dig about 0.035 bitcoins 24 hours a day according to the computing power and difficulty of the whole network in 2013. Mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, the computing power after "grouping" can surpass the single graphics card of most users. 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. Taking into account the hardware price and other costs, there is a considerable expenditure in mining< br />
Among the companies taking over pumpkin chips, asicme, founded by Yang Yaorui, the founder of xiaonei.com, is well-known. According to asicme, its procts are divided into three grades, with prices of 3000 yuan / 11500 yuan / 45000 yuan respectively. Asicme currently receives orders with a total value of more than 7 million yuan per month, and is expected to ship in September
F Jun said that asicme's mining machine is a typical "futures mining machine". The characteristics of futures mining machine are that users pay first and then ship. The delivery time is uncertain, and once the deposit is converted into payment for goods, no refund will be accepted. Mr. f once paid 9000 yuan in April to buy a bitcoin mining machine (Butterfly machine) in the United States. Now in July, the butterfly machine has not been delivered to Mr. F
even so, Mr. f doesn't intend to ask for a refund. He says that if he has a bitcoin miner with tens of thousands of yuan in hand now, he can earn back the cost in one month and make a net profit in the future
in addition to pumpkin Zhang's bitcoin mining machine and butterfly machine in the United States, a Shenzhen manufacturer is also active in the field of futures mining machine. The spokesman of this manufacturer is called "friedcat", and bitcoin diggers also call this company "roast cat". In the middle of last year, roasted cat announced the success of developing bitcoin mining machine. It issued shares to global netizens to raise funds (it is called forum IPO) to proce mining machine. After the mining machine is successfully proced, its income will be distributed to investors
according to an official publicity material, roasted cat raised about US $100000 through crowdfunding in August 2012, manufactured chip samples of mining machines at the end of the year, and paid dividends for the first time on January 19 this year. Baked cat claims that after only one dividend,
at the beginning, all investors have earned back the cost. At present, the market value of baked cat stock has exceeded 130 million US dollars
at present, bitcoin mining machine can generate a lot of profits, but a bitcoin mining machine employee admits that this kind of life won't last long. Avalon mining machine can generate 200000 profits every day in the past. Now it takes at least 30 days to buy a mining machine for tens of thousands of yuan. It's hard to say how long it will take to recover the cost after the mining machine is shipped in September
the person in the instry also said that in the long run, it is only a matter of time before this generation of bitcoin miner is overtaken. In the future, there will be more advanced bitcoin proction equipment with stronger computing power. Once these equipment appear, the bitcoin miner sold for tens of thousands of yuan will be eliminated just like the previous mining graphics card
