What is the height of the virtual currency feeding pool

1.

This is the share of ore pool in the past three months:

{rrrrrrr}

but in fact, it's of little use. It's just the difference between 100 yuan and 100.5 yuan. If your calculation power is really big, it may be much worse, but if it's ordinary, it's not much different. It is more important to choose one with low or free service charge

mining is perhaps one of the most important components of the bitcoin ecosystem. Miners need to solve complex mathematical problems, so as to ensure the smooth implementation of the transaction. These problems are so complex that they are difficult to solve even for extremely powerful computers. Computers need work and luck to solve these mathematical problems, just as miners dig underground. The chance of solving this problem correctly is about one in 13 trillion

bitcoin mining has two purposes. Firstly, by solving mathematical problems, bitcoin miners can verify the transaction information, so as to ensure the security and reliability of bitcoin payment network. Miners are the people who ensure that transactions are accurate and that there is no "double payment."

Secondly, when the computer solves these complex mathematical problems on the bitcoin network, the system will generate new bitcoin, which is similar to the process of mining gold from the ground. The reward is called "block reward", and after the event called "halving", its amount will be periodically halved. The newly discovered concept of bitcoin is an important part of bitcoin protocol. The bitcoin obtained by the miners is brand new and has never been in circulation before

since miners will eventually sell the bitcoin, it is also an important source of supply and liquidity. As chainalysis reports, many digital currency exchanges rely on miners to receive bitcoin and increase their liquidity. Typically, exchanges get about 88% of bitcoin from other exchanges, and bitcoin miners are the largest source of the remaining percentage. As you can imagine, there is fierce competition between exchanges to receive bitcoin directly from miners

further enlarge the map, most of the mining activities are only carried out in four provinces, the first two provinces are Xinjiang and Sichuan, accounting for nearly half of all bitcoin mining in China. Electricity prices are cheap and the weather is cold in these areas. This helps to keep mining profits and equipment cool ring the 24 / 7 operation and maintenance period of bitcoin mining

but this is nothing new for digital currency issuance. For many years, China has been a major market for bitcoin miners e to its cheap electricity and abundant resources. Bitmain, f2pool and Canaan are all located in China

whether this is a negative or positive message depends on your point of view. But for decentralized, distributed, unlicensed networks, geographic regions across multiple entities are more healthy for the entire ecosystem

4. The main reason is that the distribution mode of bitcoin is different: according to the operation mode, the common bitcoin pools are as follows: PPLNs, PPS, DGM, P2P ool, etc.

PPLNs: (the purest Group Mining) full name is pay per last n shares, which means "pay income according to the past n shares", which means that once all miners find a block, You will allocate the currency in the block according to the proportion of each person's own shares Share means share)

in PPLNs mode, luck is very important. If the mine pool can find many blocks in a day, then everyone's dividend will be very large. If the mine pool can't find any blocks in a day, then everyone will have no income

PPS: pay per share mode --- this mode is to pay for each share immediately. The expenditure comes from the existing bitcoin funds in the mine pool, so it can be withdrawn immediately without waiting for the block generation or confirmation. In this way, the operation behind the scenes of the pool operators can be avoided. This method reces the risk of miners, but transfers the risk to the pool operator. Operators can charge fees to make up for the possible losses caused by these risks

in order to solve the problem that PPLNs sometimes has a high profit and sometimes has no profit, PPS adopts a new algorithm. PPS estimates the daily available mineral resources of the mine pool according to the proportion of your computing power in the mine pool, and gives you basically fixed income every day

do you feel that this is a stable job? In fact, in order to avoid the risk of loss, the PPS model often charges a high handling charge of 7% - 8%< DGM: Double geometric method. It combines PPLNs and geometric reward type, so that the pool operator can avoid part of the risk. The pool operator will collect part of the excavated currency in a short time, and then return it to the miners with normalized value, such as charge and discharge of electric capacity. If you are lucky, you will get less money for each block and more money for poor luck

175btc: the mining node of 175btc works on a shares chain similar to bitcoin blockchain. Because there is no center, it will not be attacked by DOS. Unlike other existing mine pool technologies, each node's working block includes bitcoin paid to the owner of shares in the early stage and the node's own bitcoin. 99% of the reward (50btc + transaction cost) will be distributed equally to miners, and the other 0.5% will be awarded to those who generate blocks

bitcoin home has a detailed introction.

5. It doesn't matter, because the number of data blocks in all mines is global (each data block contains about 25 bitcoins). The only important thing is which mine is relatively stable and will not be offline e to a large number of visits. In fact, few of them are offline
the old mines are very stable, such as bitcoin.cz and BTC

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 cost

③ 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 technology

4. 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 agreement

bitcoin 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

7. The fish pond is stable. However, the pool owners are all black, and there are no traitors or merchants.

8. HTP was up more than 30 times before. Longchi issued a power currency, called HRT. I don't know if it can rise at that time. HRT will be on the coinsuper exchange in December. Coinsuper is one of the initiators. At the same time, cen with coinsuper platform currency can also lead the airdrop of HRT, so you can pay attention to it at that time.

9. Dog coin has been controversial since its birth. Some people say it is the most popular competitive coin, while others say it is a joke

in fact, virtual coin players with a little common sense all know that dog coin has the following fatal defects:

1. First of all, the code of doggie coin is completely copied from Leyte coin. The wallet of doggie coin in the early days has LTC words; Secondly, the founder of dogcoin left the development team in April 2014 and announced twice to quit dogcoin community; Thirdly, up to now, dogcoin still does not have a stable development team. Most of the online volunteers who joined dogcoin development team in the early days have quit. After the founder of dogcoin announced to quit dogcoin community again in March 2015, the development work actually stagnated

2. Dog money has no support of calculation power, that is to say, it has no real value, and its price performance is purely the result of speculative market game. In September 2014, in view of the collapse of computing power, doggy coin abandoned the mining mode and implemented auxpow, that is, to give doggy coin to any mine pool supporting this mechanism. This means that dog money is no longer the object for miners to profit from mining by purchasing equipment. The reason why the mine pool chooses to support dog coin is to get free dog coin< 3. There is eternal inflation. Under the background that most virtual currencies choose a fixed total amount, dog coin is set to increase by 5.2 billion every year, which makes it face serious inflation pressure. Because the new dog coin is given to the mine pool for free (the gift mechanism may be cancelled at any time), the miners will not have any feelings for the dog coin, they will only sell all the new mines. Inflation setting is an innovation of the founder of dog coin, but it completely violates the pricing principle of virtual coin: that is, under the premise of fixed total amount, through periodic halving, let the computing power and price reach a balance, so as to form a reasonable pricing mechanism. Dog money does not abide by the principle of fixed amount, and now even the computing power has been given up, indicating that it is not a standard virtual money

4. Illegal use of the logo registered by ultra Pro company may be prohibited at any time. As we all know, the dog coin borrowed the well-known Chaigou's head picture from the Internet. The "foundation" established a year later claimed to be trying to rush to buy Chaigou's head picture. The effect was just to comfort the fans. At present, ultra Pro company tacitly allows dog coin to borrow its logo, but it may be withdrawn at any time

5. Chinese speculators have completely dominated dog currency trading, and the trading volume of domestic exchanges accounts for 90% - 95% of the global total. It can be said that dog coin has been fully accepted by the Chinese, and the degree of nationalization is far higher than bitcoin, reborn coin, bitstock, and even higher than Leyte coin. The terrible thing is that Chinese speculative market is seriously separated from foreign community culture. The Chinese controlled the trading volume and chips, but never went deep into the foreign community of dog coin. They not only did not participate in any development of dog coin, but also completely ignored the tip and charity culture of foreign dog coin. Chinese speculators regard foreign communities as "idiots" who constantly create favorable conditions. Foreign communities regard Chinese speculators as the cancer of price manipulation. This is the separation of the interests of speculators and currency experimenters, which is inexcusable and irreconcilable

6. At the price of 1%, the main value of 100 billion yuan is 100 million yuan, and the annual value of 5.2 billion yuan of new mines is 5.2 million yuan. In the off-season, the global daily trading volume of dog coin is only 100000-150000 yuan. In case of systemic risk and large-scale cash out of users, it is impossible to have enough funds to resist the current price. So, where did the money go? The answer is that most of the locked up funds have been taken away by miners, and there is no possibility that these funds will return to the dogcoin market. If you want to get rid of the powder, you can only make a false appearance and cheat the new people to add fresh blood.

10. Block chain is now a very hot term. As in the past few years, the concept of "Internet plus" has come up with many blocks. But in practical applications, the technology of block chain is still very few. The future direction is to really use the chain of blocks to the actual, medical electronic files, electronic data, electronic contracts, and what kind of things. In the market, blockchain should be used for data preservation, original protection and electronic signing. After all, it is a high security technology. It seems that the original warranty and contract warranty of easysecurity are able to protect data in this way.
