Bitcoin mines and miners
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
This is the pool share in the past three months:
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 beforesince 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
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.
as tens of thousands of miners compete for the right to pack, the probability of a single miner seizing the right to pack is very small, and the output is very unstable. It is possible to grab the right once an hour or not once a year
in order to stabilize the mining output, miners often choose to join the mining pool. The mining pool integrates the computing power of a large number of miners and occupies a certain share in the total computing power of the whole network, so as to obtain a more stable mining output. After charging 2% ~ 4% of the pool handling charge, the output is distributed to the miners according to the miners' computing power
it's just like that it's hard for one person to win the lottery, so the mine pool organizes many people to buy the lottery together, and after winning the lottery, they are distributed to everyone according to the amount of contribution.

everyone can set up a mine pool, if you want, and someone else wants to join
note that if no one joins, you are the only one competing with others in this mine pool. I'm afraid your computing power is not a drop in the ocean in the whole network, and the success rate is too low
therefore, most miners join in the large mine pool and do not set up their own
of course, if you have the strength, you can also set up your own mine pool. This information is public, and you can use the Internet. thank you.

Nakamoto's mining is unreliable
On October 31, 2008, a person named Nakamoto published a research report called bitcoin: a peer-to-peer cash payment system on a secret cryptography discussion group, which elaborated the new idea of e-moneysoon after, he developed an operating system for bitcoin issuing, trading and account management on the platform of P2P (peer-to-peer or person to person) peer-to-peer network and distributed database, combining the working mode of open source software and block cipher in cryptography
the system enables all nodes throughout the peer-to-peer network to reach network agreements according to their seed files, so as to ensure fairness, security and reliability in currency issuance, management and circulation
after the advent of bitcoin, it quickly attracted the following and attention of geeks. However, what is puzzling is that after leaving bitcoin in cyberspace, Nakamoto Tsung has not been as frequently active in the bitcoin community as before, but graally faded out of the public's sight
in the spring of 2011, after leaving behind the sentence "I started to do something else", Nakamoto completely evaporated from the Internet space. No one can know his real identity, only that this mysterious figure left 2 million bitcoins for himself in the earliest block he owned, and these bitcoins have not been passive yet
people want to see the true face of Nakamoto, and even use the powerful human flesh search tool to search, which is still fruitless, Even the two Google engineers who later took charge of repairing the bitcoin project claimed that they had never found and met Nakamoto at the scene
extended data mining is a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times
miners provide algorithms for bitcoin network in exchange for the opportunity of bitcoin reward. The miners verify each new transaction and record it in the general ledger
every 10 minutes, a new block will be "mined", and each block contains all the transactions from the generation of the previous block to the present, which are added to the blockchain in turn
we call the transactions included in the block and added to the blockchain "confirmed" transactions. Only after the transaction is "confirmed" can the new owner spend the bitcoin he gets in the transaction
