It's a bee pond

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

2.

After the computing power of the whole network has been improved to a certain extent, the probability of getting rewards is too low, so that some geeks on "bitcoin talk" can develop a method that can combine a small amount of computing power and operate jointly, and use this method to build websites

in this mechanism, no matter how much computing power an indivial miner can use, as long as he participates in mining activities by joining the mine pool, no matter whether he has successfully mined effective data blocks, he can get a small amount of bitcoin reward through his contribution to the mine pool, that is to say, many people cooperate in mining, and the bitcoin reward is shared by many people according to their contribution

as of January 2019, the top five bitcoin pools in global computing power are btc.com, pool, antpool, flush pool, and f2pool. At present, about 70% of global computing power is in the hands of Chinese miners

extended data:

handling charge:

bitcoin miners will charge a small amount of fees for most transactions, the main purpose of which is to prevent people from sending a large number of boring small transactions and wasting network resources. At present, most of the handling charges for each transaction are & T 3647; 0.0001/kb (0.0001btc / KB). In fact, after 0.9.0, the default handling charge will be reced to & 3647; 0.00001/KB(0.00001 btc/KB)

because the amount of data occupied by most transactions is less than 1 kilobyte, generally speaking, the amount of data is less than 3647; 0.00001 (0.00001 BTC / KB) is enough. At the same time, in the future, when the bitcoin block rewards are less, the service charge will become the main source of miners' income, and the service charge of bitcoin will be related to the number of bytes occupied by the transaction

at present, the calculation standard of service charge in bitcoin system is not mandatory, so users can not give any service charge when the transaction is in progress

however, most miners usually give priority to the transaction with higher handling charges when building data blocks, so that they can get higher remuneration when mining is successful. Therefore, the transaction without any handling charges may take a long time to be processed and incorporated into the blockchain

in addition, e to the block capacity limit of 1MB and the recent increase in bitcoin transaction volume, the handling charges have increased significantly, and the waiting time for the transaction to be confirmed has also become much longer

3. It's one of the baskets with BTC;

4. According to the official website of coin'an mining pool, BTC's calculation power has reached 1.75e, 36053 effective miners, ranking 11th at present, OK's calculation power is 6.89e, and Huo's calculation power is 4.75e. At present, there is still a big gap in the coin'an mining pool. However, as a bystander, you should have a unique vision. Looking at the ups and downs of the previous coin circle, the development and launch of various new technologies, although coin an is late, it can always make the latecomer rank first. It probably doesn't take long for this ranking to change.

5. As the computing level of the whole bitcoin network is rising exponentially, a single device or a small amount of computing power can not get the block reward provided by 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. The website built in this way is called "mining pool"
because the probability of a single miner digging a block is very small, after all, it takes a lot of computing power to dig a block in 10 minutes. Even if there is such a large amount of computing power and the ability to dig, there are many competitors. So it becomes a game of 0 and 1. And the emergence of the mine pool is to break the 0 and 1 play. The computing power of a mine pool is a collection of many miners' computing power, which is far more likely than fighting alone. Every time you dig a block in the mine, you will be rewarded to the indivial according to the percentage of the calculation power of your mining machine in the total calculation power of the mine, and there will be no unfair situation.

Bee in Tang Dynasty: Luo Yin, no matter the flat land or the top of the mountain, the infinite scenery is occupied

after picking all the flowers to become honey, who will work hard and who will be sweet

No matter in the flat land, or in the mountain peak, and its beautiful scenery are occupied by bees. Honey bee, you gather all kinds of flowers to make nectar. For whom do you work hard, and who do you want to taste sweet

about the author:

Luo Yin (833-909), a poet of the Tang Dynasty, was born in Xincheng (now Xindeng Town, Fuyang City, Zhejiang Province) with the name of Zhaojian. He was born in 833 (the seventh year of Taihe) and arrived in the capital at the end of the thirteenth year of Dazhong (859). He was required to enter the imperial examination and was not born in the seventh year

{rrrrrrr}

extended materials:

creative background:

Luo Yin came to the capital at the end of the 13th year of Dazhong (859 A.D.) and should take the imperial examination. The author is disheartened and resentful when he sees people working hard in the fields and some court officials getting something for nothing. This may be the reason why Luo Yin wrote this poem "bee" which alleges the reaper for nothing

appreciation:

this poem grasps the characteristics of bees, without affectation, carving and painting, and not paying attention to words, though it is plain and thoughtful

The living conditions of bees are constantly shuttling and working among mountain flowers, and their vast territory gives them considerable space to display their skills“ No matter "infinity", bees "occupy all the scenery" in their hard work. In simple writing, it seems plain and straightforward, almost appreciating and praising. In fact, it is ingenuity, which makes the groundwork for the following discussion

The last two sentences are closely connected with the image of "bee" and extend and expand the image of "laborer" symbolized by it, saying "for whom do you work hard and for whom do you want to taste sweet after picking all flowers to make honey?" With a sigh

at the same time, it also raises an intriguing question: all the flowers that have been picked have turned into honey, and the hard work has finally achieved gratifying results. With the change of the subject, who is the purpose of such hard work. In a rhetorical tone, the poet accused those who were addicted to wealth. After a long sigh, he could not help feeling pity for the vast number of working people

7. Artificial bee colony (ABC) is a novel global optimization algorithm based on swarm intelligence, which was proposed by karaboga in 2005. Its intuitive background comes from the behavior of bee colony. Bees carry out different activities according to their respective division of labor, and realize the sharing and exchange of bee colony information, so as to find the optimal solution of the problem. Artificial bee colony algorithm is a kind of swarm intelligence algorithm.

8. It's necessary to press bees in spring and autumn. First of all, remove all the excess skin. If you press one or two pieces, you won't be afraid to have more bees than your spleen., Bees must be more than the spleen before they can multiply. It's very easy to spell out all the little ones, not count them as boxes or groups. It's also very easy for you to separate them when they develop. The number of bees is small and the ability of rearing is low. Although they can barely raise a number of bees, the worker bees are not very healthy. The less robust bees have poor collecting ability. They can't catch the upper breath and the lower breath, and their life span is short. Don't keep them all day long. The weak group can only watch others make honey.

9. Bee
[Tang] Luo Yin
no matter the flat land or the top of the mountain,
infinite scenery is occupied [1]<
after collecting all the flowers into honey,
for whom is hard work, for whom is sweet [2]

[note]

[1] occupy: occupy, occupy. These two sentences say that bees occupy all the spring time and work hard to collect honey everywhere

[2] is (W) è I didn't): for, here< No matter on the flat land or on the top of the mountain, all the places where flowers are in full bloom are occupied by bees. Who are they busy for in the end? Who brews mellow honey for

this poem praises the noble character of bee's hard work, and also implies the author's hatred and dissatisfaction with people who get something for nothing. This poem has several characteristics of artistic expression: the desire to seize, so give, anti drop strong; Narrates the rhetorical question, sings the sigh to have the sentiment; The implication is profound and can be interpreted in two ways

this is a fable poem. The bees in the poem are thousands of ordinary farmers in feudal society. They have worked hard for generations, but the fruits of their work have been plundered by the cleaners“ Who are you working hard for and who are you sweet for when you have gathered all the flowers and turned them into honey? " The conclusion is a rhetorical question, which shows that the bees who work hard to make honey work all the year round but get nothing. This implies that the exploiters get nothing, which makes the meaning of the poem profound and powerful

cold bees pluck chrysanthemum stamens

swim in the clear sky to find the chrysanthemum cluster
on the pistil with sound, even in the fragrance
go to live in the fog and follow the wind
finally, I feel ashamed of butterflies, not communicating with dreams<

the small garden is full of flowers, and the back door is full of thoughts
concubine Mi's waist is thinner than Lu's, and empress Zhao's body is lighter than the wind
the red wall is lonely, the cliff is honey exhausted, the blue curtain is far away, and the fog nest is empty
in Qingling, the pink butterfly will meet in mid February<

he is slender in the waist and used to dive to the bottom of the flower
after hard work becomes honey, hard work is sweet.
