Calculation power of mine stealing machine
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
if there are only one or two miners, you can choose to dig at home, rent an empty house in a slightly larger remote point, and use it as a special machine room, so that the miner will not disturb the people and it is convenient for you to visit at any time
if there are dozens or even hundreds of mine machines, it is recommended that you choose mine trusteeship. First, the electricity charge of mine trusteeship will be cheaper than that of indivials, and there are special personnel to take care of mine machines. The inconvenience may be that most of the mines are located in Northwest and southwest provinces, which may not be convenient for you to understand the actual situation, but you can also choose the background software to monitor your own mine machines, The selection of specific mines can be evaluated according to the quotation
if you don't know much about this area before and don't have a miner, you can choose to buy cloud computing power. This kind of miner is only used in a different way. The ownership of the miner doesn't belong to you, but is rented to you
the advantage of the mineral machinery trusteeship lies in the fact that it is not easy to manage; Annual regular electricity subsidies, cheap electricity; 24 hours a day without power cut to dig money; There is operation and maintenance technology in the mine 24 hours on call, problems can be solved immediately; If the power board is broken, it needs to be returned to the factory. The company will have machines to make up the power. However, it is suggested that when you choose a mine, you should consider the quotation of mine management fee and electricity fee
if you have any other questions, please ask me. I hope I can help you, thank you!
A: first, block height does not refer to the capacity of the blockchain
Second, the connotation of block heightblock 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 block2. 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
Theblock 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
Theblock height is not a unique identifier
as long as there is enough capital and cheap electricity, as well as computers with superior performance, the payback cycle is very short. Moreover, if you are a believer in bitcoin and want to collect money, mining is undoubtedly more cost-effective than speculation. Take the latest miner on the market, ant miner S19 Pro 110t, for example. The market price is about 20000 yuan, the calculation power is 110th, the total power is 3250w, the electricity charge is 0.3 yuan / kWh, the daily output is 0.000924 bitcoins, the income is about 59.27 yuan, and the electricity charge is 23.4 yuan, the daily net income is 35.87 yuan. If the price is in equilibrium, the payback cycle is about one year and seven months
the annual income of bitcoin cloud computing power mining can be more than 20%, which is far higher than most of the investment. It is the best choice for most Xiao to invest in bitcoin mining. As an early established cloud computing mining platform in the instry, easy direct mining provides users with diversified investment options. The calculation power of the mining machinery can be checked in real time, the income will arrive every other day, and it will be redeemed free of charge when it is e. At present, bitcoin mining still has a large income. As long as there is enough capital and energy, we can get high income by mining bitcoin. But for Xiao, it is still the best choice to obtain stable income through cloud computing power mining
