What is the relationship between computing power and difficulty

1. According to the data of spider mine pool:
BTC full network computing power 153.280eh/s, mining difficulty 21.72t, current block height 672055, theoretical income 0.00000690/t/day
the total network computing power of eth is 418.403th/s, the mining difficulty is 5380.94t, the current block height is 11923460, and the theoretical profit is 0.00709464/100mh/day
BSV network computing power is 0.544eh/s, mining difficulty is 0.08t, current block height is 675889, and theoretical income is 0.0081/t/day
BCH's whole network computing power is 1.596eh/s, mining difficulty is 0.20, the current block height is 676209, and the theoretical profit is 0.00056395/t/day<

2. Computing power refers to computing power. 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", Unit is written as hash / s, which is the so-called workload proof mechanism pow (proof
of
work)
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.

3. Computing power (also known as hash rate) is a measure of bitcoin network processing power. That is, the speed of computing hash function output for computer (CPU). 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 the computer's 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 the so-called proof of work mechanism (POW)

recently, bitcoin's network computing power has entered the era of P computing power (1P = 1024t, 1t = 1024g, 1g = 1024m, 1m = 1024k). In the ever-increasing computing power environment, the arrival of P era means that bitcoin has entered a new stage of arms race

computing power is a measure of the total computing power of the unit that generates new blocks under certain network consumption. The single blockchain of each coin varies with the time required to generate a new transaction block.

4. I saw it on a forum and said it was two hours, but the details are not clear

5.

At the end of 2017, digital currency experienced explosive growth and Waterloo like decline in 2018, and now it tends to be stable. During this period, a large number of investors poured into the currency circle, and all kinds of digital currencies need to be bought and sold through exchanges or digital currency wallets. However, in 2018, there were frequent incidents of exchange digital currency theft, so more and more traders chose to store digital assets in digital currency wallets, Sort out the five most well-known digital currency wallets and let's get to know them

Bitpai (score: 8.5)

bitpai is a comprehensive blockchain asset service proct based on HD wallet. Its main functions include: sending and receiving, buying and selling, accelerating transaction, etc. The user controls the private key, and the coin after the transaction is completed is directly kept by the user. At present, the currencies it supports mainly include BTC, BTC, ETH, some erc2.0 tokens, qtum, HSR, dash, safe, LTC, LCH, Zec, etc and Doge

advantages: the balance of the current digital currency can be displayed at the top of the front page of the wallet, and the upper left corner can be switched to other digital currencies, and the currency balance can also be switched from quantity to legal currency value. There are many functions in the middle, such as issuing currency, receiving currency, one click trading, etc. the broadcast of each transfer transaction is displayed below, and the completed transaction can also be queried in the transaction record. After leaving the bitpai app interface for a period of time, you need to unlock it when you re-enter, which improves the security of the wallet

deficiency: Only Mainstream currencies are supported, other small currencies are not supported, and the number of currencies is 10 +. The page setting is not user-friendly, and various parameters make it difficult for users to use. In addition, the security is worrying: Recently, there is a problem with bitpai IOS version, and the application can't be opened, and the official said: if you unload it carelessly, the assets in your wallet may not be recovered! It's still in Apple communication

7. According to the relevant literature of bitcoin, in 2140, 2100 bitcoins will be proced and will not grow. According to the principle of bitcoin, after 33 halving periods, the mining output of each block will reach 0.58 Cong, less than the minimum unit of one Cong. The interval of each half rection is 210000 blocks, and the total proction time (2140 years) given in the above literature is calculated from the proction time of each block of 10 minutes 210000 * 10 / 60 / 24 / 365 = 3.9954 * 33 = 132 years. Since 2008, 132 years later, it is 2140 years)
however, it is an ideal state that the "proction time of each block is 10 minutes" used in the above calculation method, which is only true when the computing power and difficulty of the whole network do not change. Looking at the bitcoin blockchain, it is not difficult to find that bitcoin's whole network computing power has been growing for a long time, and the difficulty of mining has also increased. Therefore, it is not difficult to find out that the above calculation is not tenable and there is a huge error.

8. Recommended route:

get on Metro Line 1 (Shanghai railway station) and take 9 stops to get off (Shanghai Gymnasium station) for about half an hour. There will be no traffic jam in the subway and the time is easy to grasp. It's best to take the subway to catch the time

have a smooth journey..
