Bitcoin room fangshandong Hydropower Station
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

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
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad 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 some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned

mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
Although many countries do not recognize the value and status of bitcoin, bitcoin is still popular in recent years, and its existence is controversial. Some people say that it has no practical significance, just a number. If it is not officially recognized by the world, mining is a constant waste of energy. Some people say & lt; No one can be sure whether bitcoin is a black horse or not
in fact, bitcoin is calculated and proced through computer networking, also known as mining. At the beginning, there was a personal computer to dig, but the efficiency was relatively low, and the cost of graphics card was low. Then there was a special bitcoin mining machine, ranging from several hundred to two or three hundred thousand yuan
when we talk about bitcoin, we naturally need blockchain because of the blockchain, bitcoin can become bitcoin. It is a secure general ledger for all payments and transactions. It can be said that everyone can contribute to the update. We need to solve a very complex mathematical problem by brute force& mdash; Hash algorithm to complete a block
many people want to know the value of a bitcoin. In fact, the price of bitcoin is changing all the time. We need to check the figures of that day. At present, the price of a bitcoin is less than 30000
AC can be easily increased or decreased by transformer, so as to realize long-distance transmission, and the rated voltage of electrical equipment with different power can be adjusted. This is an advantage of AC. power line can be connected with electrical equipment to realize power transmission. But wire resistance, current through heating, this heat is useless, nothing is wasted. In the transmission of electric energy, how to rece the energy loss is studied, so as to effectively use the power resistance
line, now it's me, so the power line loss is p = the total length of I2R line. Design L, the cross-sectional area s of the conctor, knowing that the starting resistance R = P L / s
the actual transmission power method, considering various factors, selects cross transmission voltage and conctor cross-sectional area according to different situations. Large generators proce voltages of 1500 V, 13800 V, 15750 V and 18000 V, which cannot be transmitted directly. In the power station, step-up transformer is needed to boost the power supply, and then it is transmitted to the remote. China's long-distance transmission uses voltage of 110000V, 220000v and 33000v, and voltage supply of 500000 V has been adopted in some areas. The highest test transmission voltage in the world is now 1.15 million volts. Voltage
long distance transmission is very high, and the direct application of electrical equipment, so the power area, as you said, according to different users, establish county-level substation, such as 220kV, 110KV, 35kV, 10kV substation, rece the voltage step by step, and the voltage drops to 10000 V, and send it to the power station that needs high voltage, and the voltage drops to low voltage of 220 / 380 V, for general users, such as families Schools, shops, organs, enterprises and institutions
with the construction and development of urban and rural areas, the distribution network for China's power consumption is increasing rapidly, and the task of 10kV power supply is becoming more and more important. In order to ensure 10kV power supply and distribution network with increased safety, economic and reliable operation, China has launched a matching power planning and practical design experience, For example, the design code of power supply system and technical specification for design of 10kV substation and 66kV and below overhead power lines, design specification for overhead distribution lines, design specification for insulation on overhead distribution lines, design specification for power engineering, 3 ~ 110kV High voltage cables, are included in the design code for rural power network planning and design as urban power grid planning and design guide and urban planning standard Code for design of power distribution devices "code for design of relay protection and automatic devices", "code for design of electrical measurement and energy metering devices" and "Atlas 10kV and below power distribution line project" Atlas 10kV and below power distribution equipment project "of" 10kV and below atlas ". Friends who are interested in consulting county power professionals can also borrow books from them.
if bitcoin is not put into actual use, it may be a waste of resources according to media reports, a research institute report shows that bitcoin consumes a lot of power resources every year. If we consider the power consumption of bitcoin mining in the latest year as a country, the annual power consumption of bitcoin has exceeded that of the Netherlands and the United Arab Emirates. If all the British hot water pots are powered on, it can last 27 years. According to the introction of professionals, bitcoin needs continuous computer calculation to obtain new blocks, and because the total amount of bitcoin is fixed, it needs more power calculation in the future to win bitcoin, and this process is called mining
