Investment pool
Mine pool refers to:
as the computing level of the whole bitcoin network continues to rise exponentially, a single device or a small amount of computing power can not get the block reward provided by the bitcoin network on the bitcoin network
after the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly, and the website established in this way is called "mine pool"
extended data:
the existence of the mine pool reces the difficulty of bitcoin and other virtual digital currency mining, reces the mining threshold, and truly realizes the bitcoin mining concept that everyone can participate in
but its disadvantages are also very obvious, because computing power is connected to the mine pool. As a mine pool, it will have huge computing power resources. In the bitcoin world, computing power represents the bookkeeping right, and computing power is everything. If the computing power of a single mine pool reaches more than 50%, it will be easy to launch 51% attacks against virtual digital currencies such as bitcoin, The consequences are very terrible:
the mine pool can make the mine pool with 49% of the remaining computing power have no harvest, instantly quit the competition and go bankrupt. The mine pool's computing power exceeds 50%. If 51% attack is launched, it will easily occupy all the effective computing power of the whole network
how to mine a mine pool
the location of a mine pool is also very particular. It's not that a mine pool can be built anywhere, but it needs early-stage capital investment. A mine pool is to combine a single mining machine together. Because of the collection of many miners' computing power, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher. The mine pool will distribute rewards according to the contribution value of each equipment
there are many mines all over the world, and the scale of each mine varies from big to small. Generally, small mines no longer have great advantages. Large mines have many miners for mining. For each miner, he can join any mine or join multiple mines at the same time, The first task of the mine pool is to distribute the income to the miners
(1) PPLNs method
this method gathers the shares g by all miners together. Whenever a certain amount of shares is accumulated (generally 30 million shares), the mine pool will allocate the profits of the previous stage to the miners according to the proportion of contribution
in this way, the income of miners depends entirely on the time needed to dig 30 million shares in the mine pool. If you are lucky, you can dig them in a short time, then the income of miners will be more, otherwise it will be less. In return, the pool charges a 3% tax
(2) PPS mode
for users, the income of this mode is relatively stable
the profit mainly depends on the miner's mining speed. As long as the mining speed is stable, the corresponding profit can be obtained, and the profit is real-time, that is, the mine pool will pay the profit for the miner while the miner is running
obviously, every time a block is calculated, the mine pool has paid for all the miners. If the block fails in the subsequent confirmation link, all the losses will be paid by the pool operator. Therefore, this method reces the risk of the miners, but transfers the risk to the pool operator
therefore, usually the ore pool can charge a handling fee to make up for the possible losses caused by these risks. In this mode, the tax of the ore pool is 7.5%
the above is about how to mine. The difficulty of mining has greatly increased, but the mining army is expanding. If the basic equipment does not meet the standard, it will be difficult to gain in the mining instry, because the value of the virtual currency may not be equal to the price of an equipment, and many miners are not just digging bitcoin, Instead, we choose other virtual currencies to mine.
look at the balance sheet, profit, etc. first, go to this company to look at its report. Look at the profit from its sales revenue.
for example, what is the proportion of profit. From the size of gross profit, we can know how a company's buyer is.
if the proportion of gross profit and sales is large, From the dividend, we can see whether the company pays attention to investment,
or short-term profits. From the ratio of working capital and current liabilities, we can see the company's ability to repay others
if it is too low, it can explain the management efficiency of the company from the side. If it is too high, it also shows that the company is not good at investment.
in other aspects, you can understand its background, evaluate its ability, and whether it is suitable for the company from the perspective of the company's managers. Or from the past performance, you can see how the company's loans are. If there are too many, there will be risks, or lack of confidence. Dividing the net profit by the sales volume, we can know the consumption management of the company in other aspects, such as water and electricity, office supplies, etc. if the result is relatively high, it means that the company is economical and orderly. If it is relatively low, it means that the efficiency of the company is not high,
if there is a significant increase, the company is in the right direction.
Background: the financial application of blockchain technology brings high investment value
2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles
1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:
in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost
2. Why can blockchain solve the above pain points:
blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs
3. The application of blockchain technology in the financial field mainly includes the following aspects:
① digital currency
among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits
Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost③ digital bills
④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost
The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points
in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it
Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall) In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreementbitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain
based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network
2. Master node network
the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan
Figure 6: Mining reward model
starting from the current market situation and mine owner's psychology, AA mine pool adheres to the market-oriented concept, pays more attention to humanistic service and professional technology, and creates a new, simple, safe and stable mining service platform
technical advantages of AA ore pool:
purer mining mode: adopting algebraic average algorithm, the original PPLNs + distribution mode is better than the traditional PPLNs / PPS mode, and the income can be increased by about 20%
core driver upgrade: make blocks output faster, allocate tasks at millisecond level, adjust dynamic difficulty, and output blocks efficiently
Security and stability: distributed main network node servers are distributed in 24 cities around the world, with strong anti DDoS capability, ensuring efficient and stable revenue growth
ultimate experience: more optimized big data infrastructure, timely and rapid response, simple mining steps, easy to understand, easy mining, and enjoy the benefits.
1. If you catch the trading volume (with time limit), you can sell the mining income in the trading hall without amount limit
2. If you can't get the paper, you have to buy a miner (standard miner, advanced miner, advanced miner, any one of them). If you buy a miner, you can sell it every 1000 times
when digging to 500 or so, it will prompt that the miner needs to be activated for at least three times (buy 10 yuan). 20 30 A total of 60), to 1000 mining machine stop running, need to buy mining machine to continue to work
fixed assets and mining income:
the money bought and the BTC of 1.2 yuan are all entered into the fixed assets. The fixed assets can only be used as mining machines or merchants, and the fixed assets (only merchants) can be sold in the trading center! All the money is in the mining income. If you buy a miner, you can only sell the mining income
the promotion invites people to send three-day miner (up to 40 people) to catch fish, buy money to catch fish, trade six times, lower level buy money to buy miner to catch fish, catch fish can catch a lot of good things, 24-hour miner, 20 day miner, 12 hour super miner with 500 computing power and so on
many people are senior two miners, and the business deposit is 30000 yuan! If the newcomers are afraid of being trapped, they will first go to the promotion and invite people to buy money for six times, a total of 310. If the subordinates buy money to buy Mining opportunities to send you to catch fish, save a wave first, and save more than 900 before going to the mining machine? Come back quickly----
there are two ways of investment: 1. Investment of mine pool fund, with an initial investment amount of 100000 to several hundred thousand; The investment cycle is half a year, and the income is higher than that of general bank financial procts. 2. Recently, the popular version of mine pool computing power investment is launched, with low threshold and stable income, mainly through leasing personal computing power to obtain a certain proportion of income; The income mainly depends on the amount of investment, the amount of calculation and the age of calculation. When the market performance of blockchain is not good, the proportion of revenue decreases or at most there is no revenue, which will not affect their own money

legal system story:
the disabled mother is seriously ill in bed, her father is an ordinary worker, and her 15-year-old son, Xiaogang, is a class cadre. Xiao Gang sees the difficulties in his family. He knows the importance of money to his mother and the whole family
ring the summer vacation, a child studying in a work study school in the neighborhood found Xiao Gang and told him that there was a way to get money, and assured him that as long as he mixed with him, he would make a fortune. Xiaogang, who is filial, is wavering, longing for "if I can get a lot of money, I can operate on my mother.". Two people a total, the goal is locked in Xiaogang a very rich primary school classmate Mingming
so they make an excuse to play with Mingming, and Xiaogang knocks on Mingming's door. After the two and a half year old children went in, in the presence of their parents, the next door child took out the kitchen knife prepared in advance and announced loudly: "robbery, take out the money!" Mingming's father subed him, and Xiao Gang, who was stupid on the spot, was sent to the police station
uncle police advised everyone to study the legal knowledge seriously, learn from Xiao Gang, study the legal knowledge seriously, and don't go astray
