600t capacity
mining has been successful, a total of one equipment (CPU mining, 4-core bar), computing power: 12.75 khash / S (generally abbreviated as KH / s)
KH / S is very rare, so is MH / s; Now the more common are GH / s, th / s, pH / s. The conversion rate is about 1p = 1000t = 1000g = 1000m = 1000K
now the basic unit is GH / s, and several hundred g mining machines are very common
[bitcoin mining machine]
bitcoin mining machine is a 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
the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
1. Machine cost: the cost of purchasing mining machine
2. Power cost: the power cost consumed by machine mining
3. Auxiliary costs: personnel maintenance, network, cable consumables, heat dissipation, etc.
for a simple example, take the mining machine of ant S9, which consumes less power on the market, for example, the calculation power is 13.5T, and the power consumption is 1400W
when the mining machine runs for 24 hours: 1.4kw * 24 = 33.6 degrees
Shenma m3, which consumes more power on the market, has a calculation power of 11.5t, The power consumption is 2150w
under 24-hour operation, the power consumption of a single machine is 2.15kw * 24 = 51.6oc
which is roughly equivalent to the power consumption of energy-saving air conditioning, but the bitcoin miner needs 24-hour uninterrupted operation, the power consumption of a single machine is very large after a year's calculation, and the step price cost of household electricity is too high, When the market is not good, the income may not be enough for the electricity expenditure, so at present, mining will choose to be hosted in the mine, which can get cheap electricity and rece the cost price of mining. The price below 30% is the ideal price, which can keep the price of bitcoin falling to a low level, and there is still some income< According to the current mining difficulty of bitcoin:
BTC revenue per ton: 1th / s * 24h = 0.00007087btc
calculated by the comprehensive 12t machine computing power, the daily output is:
0.00007087t * 12t = 0.00085044btc
then the time required for a single machine to dig a BTC:
1 / 0.00085044 = 1175 days
the time required for ten mining machines to dig a BTC:
1 / 0.0085044 = 117 days
100 days In other words, according to the current difficulty, it takes about three years for a single miner to proce a bitcoin, 3.9 months for ten miners to dig a bitcoin, and 11.7 days for a hundred miners to dig a bitcoin. The cost of a single miner is about 8500, Ten are around 85000, one hundred is 850000, less than one million, and one month's income is more than two bitcoins. According to the current price of bitcoin, the price is about 120000. So, although the income of bitcoin mining is not as good as before, it is still considerable compared with other investment projects
however, these benefits do not include decting the cost of electricity charges and later maintenance of machines, so the premise of mining is to find a mine with low electricity charges. If the quantity is large, we need to find a safe, reliable and stable mine. What's more, we need cheap electricity to lower the cost price.
Computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second
in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow
computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value
therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world

1 KH / S = 1000 hashes per second
1 MH / S = 1000000 hashes per second
1 GH / S = 1000000000 hashes per second
1 th / S = 100000000000 hashes per second
1 pH / S = 100000000000 hashes per second
1 eh / S = 100000000000 hashes per second

What does 1p mean
first of all, 1p computing power is equivalent to about 1.05 million g, which means that if you have 1g computing power of the whole network, you can get almost 1.05 million of bitcoin output of the whole network. According to the output of 3800 bitcoins per day, we can see that the daily income of 1g of computing power has dropped to 0.0036 bitcoins, which is about 2.7 yuan according to the current market price. If the electricity cost and mining machinery hardware cost are included, the profit is almost gone
secondly, 1p's whole network computing power seems amazing, but in fact, in a year's time, you will think it's just a pediatrics, because cointera will launch 2p miner in December, and bitmine will launch 4P miner in March next year. If these companies are not put in biochemical weapons by Syria, it should be expected that bitcoin's whole network computing power will reach more than 10p in a year's time, By then, 1g of computing power will only be able to dig 0.00036 bitcoins a day.
computing power refers to computing power, refers to that in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second, is the representative of its "computing power". The unit is written as hash / s, which is the so-called proof of work mechanism (POW)
1. Gravity g = mg
(vertically downward, g = 9.8m/s2 ≈ 10m / S2, the action point is at the center of gravity, applicable to the earth surface)
2. Hooke's law f = KX
{along the recovery deformation direction, K: stiffness coefficient (n / M), X: deformation variable (m)}
3. Sliding friction force F = μ FN
{opposite to the relative motion direction of the object, μ： Friction coefficient, FN: positive pressure (n)}

different classification of force
1. According to the nature of force, it can be divided into gravity, universal gravitation, elastic force, friction force, molecular force, electromagnetic force, nuclear force, etc Note that gravity is not equal to gravity under all conditions Gravity does not point to the center of the earth under all conditions. Gravity is a component of the earth's gravitational force on an object, and the other component is a centripetal force. Only on the equator does gravity point to the center of the earth.)
According to the effect of force, it can be divided into tension, tension, pressure, supporting force, power, resistance, centripetal force, restoring force, etc According to the research object, it can be divided into external force and internal force According to the action mode of force, it can be divided into non-contact force (such as gravitation, electromagnetic force, etc.) and contact force (such as elastic force, friction force, etc.) There are four basic interactions (forces): gravitational interaction, electromagnetic interaction, strong interaction and weak interactionnature of force:
materiality: force is the effect of an object (matter, mass) on an object (matter, mass). When an object is subjected to a force, another object must exert this effect on it. Force cannot exist independently without an object
interactivity (interaction): the interaction between any two objects is always mutual, and the object exerting the force must also be the object under the force. As long as one body exerts a force on another, the stressed body in turn will surely add a force to the exerted body Generating conditions: the force is equal in size (the resultant force is zero, in a state of non directional static motion) or not equal, in the opposite direction, acting on two different objects, and acting on the same straight line. It can be summarized as: foreign body, equivalent, reverse, collinear. A pair of interaction forces must proce and disappear at the same time.)
Vectoriality: force is a vector, which has both magnitude and direction
simultaneity: the force proced and disappeared at the same time
independence: the effect of one force does not affect the effect of another
includes three elements: the size, direction and action point of the force. The accurate expression of the three elements of force by a directed line segment is called the diagram of force. The size is represented by the length of a scaled line segment, the direction is represented by an arrow, the point of action is represented by an arrow or the tail of an arrow, and the straight line along which the direction of a force follows is called the line of action of a force. The diagram of the force is used for the calculation of the force. When the judgment power is large, we must pay attention to the scale of the line segment, because even if one line segment is longer than another line segment, but the scale of the long line segment is also longer, the force represented by the short line segment is not necessarily smaller than that represented by the long line segment
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
extended data
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
