1.Hash rate refers to the speed at which a computer performs hash operations during the process of verifying transactions (i.e., cryptocurrency mining). These calculations involve a series of attempts to find valid solutions to complex mathematical problems.
2.Hash rate is usually measured in hashes per second (H/s), and prefixes such as mega (million), giga (billion), and tera (trillion) are used to represent it. For example, 1 Th/s means calculating one trillion hashes per second.
A. Mining Efficiency: The higher the hash rate, the greater the chance for miners to successfully mine a transaction block and receive the block reward.
B. Network Security: Hash rate is an important indicator for evaluating the security and processing power of a blockchain network. A higher hash rate means the network is more difficult to attack.
1.Lucky miner has relatively low computing power, and its current main computing powers are two categories:
a) 73K, 77K
b) 0.5T, 1T, and 4.2T
2.Different target customers. Traditional mining machines are mainly designed for mining farms, with high computing power and high noise. Lucky miner is aimed at ordinary retail investors.
3.Different mining forms. Traditional mining machines usually connect to a mining pool to mine and share coins, with more work resulting in more gain. Lucky miner generally mines in SOLO mode, similar to buying lottery tickets.
Traditional mining machines have high computing power and high noise, and the payback period can be predicted. LUCKY MINER has low computing power, aiming for big rewards with small investments. It doesn't mine continuously every day; it mines in solo mode, like a lottery, and the payback period cannot be calculated.
The computing power can only be compared under the same algorithm.
1.A computer or a mobile phone is enough. (It is only needed for the initial configuration. After the configuration is completed, neither a mobile phone nor a computer is required. As long as it is connected to the Internet, it can be used.)
2.A 2.4G network.
1.Plug in the power supply.
2.Connect the computer/mobile phone to the Lucky_xxxx hotspot and configure the local Wifi and password.
3.Prepare a BTC wallet address or register with a mining pool (FQ is required).
4.Enter the mining pool and find the mining pool URL (Stratum URL). It is recommended to use Public Pool: https://www.viabtc.com/.
5.How to determine if the mining machine is configured successfully and is mining normally? Open the dashboard to check if the hashrate is being calculated, or check in the mining pool (Mining Pool Stats).
6.If it is not mining normally, how to solve it? Change to another mining pool or re - configure it.

1.What is the sha256 algorithm?
Sha256 is a cryptographic hash function. Simply put, it is a hash function. For messages of any length, SHA256 will generate a 256 - bit - long hash value, called a message digest, which can be represented by a 64 - character hexadecimal string. Sha256 is a sub - algorithm of SHA - 2. SHA - 2 can be further divided into six different algorithm standards, including SHA - 224, SHA - 256, SHA - 384, SHA - 512, SHA - 512/224, and SHA - 512/256.
Here is an example:
For the sentence "Happy is good!"
The hash value obtained after passing through the hash function sha256 is:
e758834980d502fbdec9166b9a76aa657728546c838f59f51ae66b1ed32fb16b
1.There are many free md5 and sha256 decryption websites on the Internet that can be used to verify the hash results of SHA256. Through the md5.cn website, we can check whether our SHA256 code is correct. The operation is simple and convenient, and you can try it.
2.How secure is sha256?
SHA - 256 is very secure because the only way to obtain the same hash value is to input the same file or string. Even a small adjustment will completely change the output. This is why sha256 is so secure.
For example:
Input: Bye1
The result obtained is:
741a03a10f3de6b2eb81985d06b70f549e762d2e9a1895c5156ffc5e10ffde33
Input: bye1
The result obtained is:
d828103bd4740f22982794b6bd394839dd73f894280a631ba7e3e7e38a42c2e8
1.Regardless of the length, it always returns a 64 - character string. Moreover, even capitalizing a word will completely change the hash value. It is impossible to guess that "Bye1" and "bye1" are similar through the hash function. As we can see from the above examples, the input strings only differ in case, but the results are very different. This is why sha256 is relatively secure.
2.Is the sha256 algorithm reversible?
Since sha256 is a deterministic one - way hash function, sha256 is irreversible. That is, it is a mathematical function that accepts input of any size but returns output of a fixed size, like a digital fingerprint of a file or string. It is deterministic because the same input always produces the same output.
Sha256 is one of the most popular computer algorithms and one of the currently powerful encryption functions. Sha256 is used in cryptocurrencies such as Bitcoin. It is a highly secure and unbreakable function. At the same time, it is irreversible. As a member of the SHA - 2 cryptographic hash function family, it has never been compromised. Sha256 is a sub - algorithm of SHA - 2 and is more secure than SHA - 1.
1.Master - Bitcoin
Bitcoin (abbreviated as BTC), issued in 2009, has a return rate of millions of times so far, with a market capitalization share of over 60%. It is the founder in the field of digital currencies, with fans all over the world. It has promoted the blockchain industry single - handedly, and its strength is beyond doubt.
2.Elder Disciple - Bitcoin Cash
Bitcoin Cash (abbreviated as BCH), derived from a hard fork of Bitcoin in August 2017. As the elder disciple of Bitcoin, Bitcoin Cash was once very popular in the market. In December 2017, taking advantage of the bull market, the price of BCH reached 30,000 yuan per coin, a 15 - fold increase in 4 months compared to the 2,100 yuan at the time of the fork.
The predecessor of Bitcoin Cash was Bitcoin. After the fork, Bitcoin Cash began to execute new code, and the block size was upgraded from 1M to 8M, as if it were establishing its own independent status. However, after several years, BCH has long lost its former glory and has shrunk by 90% compared to its highest price.
3.Grand - Disciple - Bitcoin SV
Bitcoin SV, abbreviated as BSV, is a fork of BCH. In November 2018, BCH had a hard fork, and BSV was born. After the fork, the block size of BSV increased from 8M to 128M.
BSV really entered the public eye in 2020. On January 10, 2020, BSV suddenly surged by 50%, and the entire cryptocurrency market boiled instantly. After two days of a slight correction, on January 14, BSV soared by 144% again. Overnight, people exclaimed that the bull market had arrived. The surge of BSV attracted a large number of speculators and became the engine of the last small Bitcoin bull market.
4.Second Disciple - Bitcoin Diamond
Bitcoin Diamond (abbreviated as BCD) is also a fork of Bitcoin. The issued amount of Bitcoin Diamond is 210 million coins, 10 times that of Bitcoin, and the block size is 8M. BCD has a transfer privacy protection function, and transaction amounts can also be encrypted. However, due to the small number of supporters, its development has not been satisfactory.
Compared with the above two, Bitcoin Diamond is more like an airdrop reward for Bitcoin holders. At the time of the fork, it was distributed at a ratio of 1BTC:10BCD. If you had 1BTC in your hand, you could just get 10BCD. Since 81% of the total amount was used for distribution, the subsequent mining motivation was insufficient. Currently, the popularity of BCD is very low. According to Bibox data, the current market capitalization of BCD ranks 64th.
5.Third Disciple - Bitcoin Gold
Bitcoin Gold is one of the forks of Bitcoin. The main feature of BTG is the modification of the mining algorithm. In order to prevent the problem of overly concentrated computing power caused by ASIC - specific mining machines, it restricts the use of ASIC mining machines and switches to GPU mining, and uses an emergency difficulty adjustment mechanism. Generally speaking, BTG mainly aims to solve the problems of overly concentrated computing power in BTC mining and the difficulty adjustment mechanism.
BTG also experienced a slight increase when it was launched. However, due to the ineffective development team, BTG started to decline soon after its launch and has fallen by 98% so far, falling into the category of third - rate currencies.
18、 The specific definitions and characteristics of SOLO, PPLNS, PPS, and PROP mining methods are as follows:
1. SOLO mining:
A. Definition: SOLO mode refers to miners mining independently without pooling their computing power with other miners. All profits from mined blocks are exclusively enjoyed by miners, including block rewards and miner fees. If the block cannot be mined, there will be no profit.
B. Characteristics: High risk and high return, if miners produce blocks, the returns are very considerable; But if the block cannot be released for a long time, it may result in huge losses. Miners need to bear all the risks of independent mining, and block production depends entirely on luck and computing power.
C. Applicable scenarios: Suitable for miners with sufficient computing power and the ability to independently generate blocks.
2. PPLNS mining:
A. Definition: PPLNS (Pay Per Last N Shares) mode distributes revenue based on the calculation results submitted during a time period. The shares submitted by miners will not generate immediate profits, but will be distributed based on the actual number of blocks mined by the mining pool during this period after N shares are completed, according to the contribution ratio of each miner.
B. Characteristics: Delayed and volatile returns, delayed distribution of returns, and significant impact of mining pool luck values, resulting in high returns volatility. The handling fee is relatively low because the mining pool only distributes profits based on the actual number of blocks produced and does not bear the risk of isolated blocks.
C. Applicable scenarios: Suitable for miners with certain computing power and willing to bear certain volatility risks. If the luck value of the mining pool is high, it may bring unexpected returns.
3. PPS mining:
A. Definition: PPS (Pay Per Share) mode distributes revenue based on submitted calculation tasks. The miner submits a valid calculation result (i.e. share), and the mining pool calculates the corresponding revenue based on the current mining difficulty of the network, accumulates it into the miner's account, and distributes it regularly.
B. Characteristics: Stable income, not affected by the actual number of blocks and lucky values in the mining pool, ensuring long-term stable mining income. But the handling fee is higher because the mining pool needs to bear the risk of isolated blocks and low lucky values.
C. Applicable scenarios: Suitable for miners who pursue long-term stable returns, especially small computing power miners or novice miners.
19、 What is a mining pool?
Mining pool is a way of combining a small amount of computing power for joint operation. It breaks through the limitations of geographical location and connects the computing power of miners and mines scattered around the world to jointly mine.
Due to the exponential increase in computing power across the entire Bitcoin network, individual devices or small amounts of computing power are unable to obtain the block rewards provided by the Bitcoin network. After the computing power of the entire network has increased to a certain extent, the low probability of obtaining rewards has prompted some geeks on "Bitcointalk" to develop a method of combining a small amount of computing power for joint operation. Websites built in this way are called "mining pools".
The mining pool is responsible for information packaging, and the connected mining sites are responsible for competing for accounting rights. The Bitcoin rewards mined will be distributed according to the proportion of computing power contributed by each miner.
Assuming one million people participate in Bitcoin mining and the entire network has 400P of computing power, 90% of the miners have computing power of less than 1P (1000T). If a 1T mining machine is invested, it will account for 1/400000 of the network's computing power. Theoretically, it takes an average of 10 minutes to mine a block every 400000, which means it takes 7.6 years to mine a block and receive 50 bitcoins at once. So, if I find 9 miners with 1T computing power mining machines and reach an agreement, we will have a total of 10 people. If any one of them mines a block, we will divide it equally according to the proportion of each person's computing power. Then we will be a whole, with a total of 10T computing power. On average, we can mine one block in 0.76 years, and then we can mine 5 bitcoins in 0.76 years. What if we organize 100, 1000, 10000, or even 100000 people? If it's 100000 people, then on average, I can mine one block in 100 minutes. As a member of the team, my income will tend to stabilize. This is the basic principle of mining pools, which means that everyone teams up to mine Bitcoin, and you can refer to the lottery's concept of buying together.
The biggest advantage of mining pools is that they break through geographical limitations and connect the computing power of miners and mines scattered around the world to mine together. The mining pool is responsible for packaging transactions, and the mining machines connected are responsible for competing for accounting rights. In theory, the greater the computing power of a mining pool, the easier it is to mine blocks. However, from a probability perspective, each mining pool and miner have an equal probability of mining blocks. A mining pool is a fully automated mining platform, where mining machines are connected to the pool, providing computing power and generating revenue.
20、 Background of mining pool generation
In the Bitcoin world, as the number of mining participants increases and computing power improves, the probability of a single miner mining Bitcoin is infinitely close to zero, just like winning a lottery. In order to solve this problem, mining pools have emerged.
In the Bitcoin network, an average of one block is generated every 10 minutes, with each block containing a certain amount of Bitcoin. The probability of mining a block is proportional to the amount of computing power invested by miners. As more and more people participate in mining, the competition for computing power becomes increasingly fierce, and the difficulty of individual miners mining independently continues to increase. Perhaps investing a mining machine to mine, according to probability, takes 5-10 years to mine a block, which makes it almost impossible for ordinary people to participate, putting Bitcoin mining in an awkward situation.
In order to increase the probability of mining Bitcoin and reduce mining uncertainty, miners have begun to explore more efficient ways. So, the concept of mining pools was proposed, which connects the computing power of miners and mines scattered around the world to jointly mine. The emergence of mining pools allows miners to gather together for warmth, concentrate computing power to accomplish big things, and reduce the uncertainty and volatility of profits.
The mining pool industry has developed rapidly in this year, and the solo computing power that is not in the mining pool has been compressed to only about 10%. This is related to the rapid increase in computing power across the entire network, and the difficulty of mining has rapidly increased. It is already difficult to mine blocks without being in the mining pool. The development of mining is an inevitable trend under the improvement of computing power. With the rapid expansion of mining computing power, the probability of small computing power mining blocks has become extremely small. In order to avoid the risk of long-term no returns, miners adopt the approach of "concentrating computing power to do big things". Scattered computing power is connected to the mining pool according to a certain network protocol, and the mining pool distributes computing tasks to the computing power connected to the mining pool, and the centralized computing power works together to mine. The scale effect of the mining pool can ensure a relatively stable output every day, and the longer the time, the closer the returns are to mathematical expectations.
According to the allocation method, it can be divided into PPS, PPLNS, DGM, PROP, etc.
PPS： Pay rewards immediately for each share, ensuring stable returns and transferring risks to the mining pool operator. The mining pool will estimate the daily amount of minerals that the mining pool can obtain based on the proportion of computing power of miners in the mining pool, and provide miners with a fixed daily income. This approach reduces the risk for miners, but the mining pool may charge fees to compensate for the potential losses caused by the risk.
PPLNS： Based on the past N share based payment returns, there is a strong element of luck and a lag inertia. Once all miners discover a block, they will allocate the currency in the block based on the proportion of each person's own contribution to the number of shares. If the mining pool can discover many blocks in a day, everyone's dividend time will be very fast; If the mining pool fails to discover any blocks for a day, then everyone will have no income that day, and the income will have to wait until the participating blocks are fully mined before it can be distributed. At the same time, there will be a certain delay in the mining profits of newly joined miners.
DGM： By combining PPLNS and geometric reward types, mining pool operators can avoid some risks. The mining pool operator collects partial block rewards for shipments in a short period of time, and then returns them to miners in a normalized value, such as capacitor charging and discharging. If lucky, they give less for each block, and if unlucky, they give more.
PROP： After 120 confirmations, the mining pool generates genuine blocks and distributes Bitcoin based on the contributions of miners. This mode is more in line with the generation of Bitcoin blocks. Even if no real blocks are generated temporarily, if real blocks are generated in the future, they will still be allocated to each miner based on their contribution to mining this block.
21、 How to choose a mining pool?
1. Calculation rate ratio: Choose a mining pool with a high calculation rate ratio, which has strong overall strength and is trusted. There are many mining pools to choose from on the market, and new investors/miners should first choose a mining pool with a high computational rate ratio when selecting a mining pool. The overall strength of this type of mining pool is strong, with a high proportion of computing power, indicating cooperation with large and medium-sized mining plants, and also indicating that it has gained the trust of many miners. This type of mining pool, which has accumulated user evaluations for many years, is generally a well-known mining pool. For example, the Coin Printing Mining Pool is currently one of the top mining pools in the world for BTC, LTC, and ZEC computing rates, and is suitable for mining services for multiple mainstream currencies; F2Pool is the earliest BTC mining pool in China, a comprehensive virtual currency mining pool; It is a mining pool under the mining machine manufacturer Bitmain Group; AntPool is also a mining pool under the Bitmain Group. These mining pools have a large proportion of computing power, overall strong strength, and are trustworthy.
2. Good reputation: Good products and services bring good reputation, which is a reflection of the overall level. Choosing a reputable mining pool is also very important. Excellent products and services generate good user evaluations, which are a reflection of the overall level and the accumulation of domain network resources. A reputable mining pool can provide stable services, ensure the continuous and effective operation of miners' computing power, and reduce the waste of computing power and loss of revenue caused by technical failures. At the same time, reputable mining pools can also provide a fair profit distribution mechanism, allocating rewards for mining based on the proportion of computing power contributed by miners, ensuring that each participant receives a corresponding return for their efforts.
3. Convenience of "digging and selling": crucial in extreme market conditions. Choosing a mining pool that is more efficient through "digging, lifting, and selling" is crucial in extreme market conditions. There are many mining machines and mobile mining software available on the market, but different manufacturers may produce different products, which may result in ineffective adaptation between mining machines and mining pools. Therefore, choosing a mining pool that can quickly "mine and sell" can ensure miners' profits in extreme market conditions. For example, in extreme market conditions, the ViaBTC micro bit mining pool is highly praised by miners for its automatic withdrawal function of mining profits, which is free of transaction fees. On the automatic exchange page, all mining currencies can be automatically exchanged for USDT and BTC, and this feature is set to perform automatic coin exchange once per hour.
4. Targeted research: Understand the characteristics of different mining pools and find the one that suits oneself. Finally, it is necessary to conduct targeted research in order to find a suitable mining pool for oneself. When choosing a mining pool, factors such as availability and stability, revenue, geographical location, and reputation can be considered. The availability of a mining pool refers to whether the pool frequently experiences failures or network delays that prevent normal connections. Stability refers to whether the mining pool can operate stably without significant downtime. You can learn about the availability and stability of the mining pool through online forums, social media, and comments from other miners. The profit of the mining pool is very important for choosing a mining pool. Mining pools usually charge a certain handling fee, and different mining pools may have differences in the handling fee charged. In addition, the payment model of the mining pool will also affect your earnings. You can choose the most suitable mining pool for yourself by comparing the transaction fees and payment models of different mining pools. The geographical location of the mining pool is also an important consideration factor. Due to latency issues in blockchain networks, choosing mining pools that are geographically close can improve your mining efficiency. The reputation of the mining pool is also an important reference factor. Choosing a reputable mining pool can increase your trust and reduce the risk of encountering potential scams. You can learn about the reputation of the mining pool through online forums, social media, and comments from other miners.
