Realization of mine pool with Java

2.

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

3. The story is like this. In the past, there was a terrible story in every university. It said that there was something unclean in school A. every time when the 15th anniversary, Lu Xun's eyes would move in front of the school. All the teaching buildings would be cut off. The stairs would change from the original 13th level to the 14th level. The water from the water dragon head of the laboratory would turn red. And the toilet at the end of the first floor, as long as someone went in So a group of disbelieving children made an appointment to go on an expedition on the 15th day. At 12 p.m., they arrived at the gate of the school on time. Lu Xun's eyes looked to the left. They wrote down that they were afraid that when they came out, they couldn't remember if they had moved. They came to the classroom and turned on the switch. Isn't it on“ It's a lie. " One boy complained, "look again." Came to the stairway "1, 2, 3... 13 yes, it's 13 steps?" The children were a little suspicious of the truth of the legend, so they came to the laboratory again. The tap turned on the white water and it came out, "it's boring, we're coming for nothing!" The initial excitement is half gone. Finally, they came to the toilet. Although the girl said she didn't believe it, she still didn't dare to go in. So she let little C, who just said she wasn't afraid, go in and look at the table. Two minutes later, the boy came out and said, "it's all deceitful." the children broke up in a bad mood. When they went out, a doorman found them and told them how they could stay at school so late. The children ran away, and little B paid special attention to the stone statue at the door. Yes, his eyes still looked to the left, which was "deceptive." he muttered, "Hey, little B? Little c went out with you last night. Why didn't he come back? " The next morning, little C's mother called to ask. Little C didn't go to school, and the children vaguely felt wrong, so they told their teachers and parents about the adventure in the evening, and they returned to the school accompanied by alts“ what? Our eyes of Lu Xun are always looking to the right. " The headmaster listened to the children's narration and said strangely“ But when we came here yesterday, we looked to the left. "When we went out, we really looked to the right..." but there was electricity yesterday. "" we had a blackout here yesterday... How could you turn on the lights? "“ And the stairs The children quickly ran to the stairway "1, 2, 3... 12?"“ Our stairs are always 12 steps. "“ No way“ And the lab, "a child reminded." yes, the lab "and the others came to the lab. there was a dark red mark under the tap they had opened yesterday“ It's blood. "“ That... Little c went to the toilet yesterday... "Everyone felt a sense of inexplicable fear." let's go and have a look. "The headmaster also realized the seriousness of the matter... Opened the door... Little C's body suddenly appeared in front of everyone's eyes. Because of panic, his eyes were wide open, his throat was cut, and his bloody internal organs were scattered in the pool that had been dried up..." ah... "Little C's mother fainted on the spot In the past, several teachers rushed out immediately to vomit... Little B was also stunned. One second before he fainted, he caught a glimpse of little C's watch pointer stopped at 1:00... When little c entered... By the way, there was no guard on the night when they went to explore... Turn this post to more than five forums, which will not be haunted by demons and will realize a wish. Those who don't reply often... Sorry, I'm helpless

top ten Ethereum mining software in 2020

in terms of market value, Ethereum is the second largest cryptocurrency, second only to bitcoin. Ethereum's popularity among the holders has increased rapidly because it can build the whole decentralized ecosystem and applications on top of its blockchain. As Ethereum is friendly to GPU mining, Ethereum is a good choice for PC users (especially those with AMD high-end graphics cards). However, 24ker should also warn readers that at this time point, Ethereum's price is $241, which means that even if you use radon VII (90mh / s), your weekly profit is less than $7, The annual profit is about $339. However, considering the potential value-added space of Ethereum, if the price can return to the healthy range of $500-600, it means that your radon will be back in one year

if you already have Ethereum mining hardware and an effective wallet, all you have to do is to find the best eth mining software, which will help you manage the mining work effectively

in this article, we will introce the features, advantages and compatible operating systems. But before we get there... Let's talk about the basics

why Ethereum

unlike traditional currencies, Ethernet operates on the public ledger system, which makes mining itself the core power of Ethereum network. When miners receive the transaction data sent by other members of the network, they assemble them into a structure called Merkle tree, and then try to find an acceptable hash value

only one hash will be returned for each dataset, and the hash value cannot be used to dece the original data. Its purpose is to effectively ensure that the block information is not tampered with. Moreover, if someone changes even one number in any long transaction string, the output hash value will be completely different, and false transaction or fraud will be eliminated

as you can see, if there is no Ethereum mining, Ethereum network will be paralyzed immediately. Therefore, participating in Ethereum mining is not only the mining revenue, but also the support for the operation and growth of Ethereum

what is mining software< In short, mining software is a program that uses a computer graphics card (GPU) as a resource to solve complex mathematical equations. Once the equation is solved, the data is added to the rest of the blockchain

the mining software will monitor the input and output of the hardware, and display statistical data to you, such as miner speed, fan speed, temperature and hash rate

the Ethereum mining software described in this article can be connected to many available Ethereum mining pools

Ethereum mine pool

Ethereum mine pool is a resource area that is equally distributed and shared among miners. Nowadays, it has become too difficult for a person to dig a mine, so it is necessary to use the way of mining pool to fight in groups

today, Ethereum is one of the most famous choice of Ethereum mines. The pool allows its users to remain anonymous and pay only a small 1% mining fee<

top ten Ethereum mining software:

1-ethminer (Ethereum Royal)

it can be seen from the name that ethminer is specially designed for mining Ethereum, and currently supports Linux, MAC and windows. Make sure to download the version corresponding to the device's operating system

in addition to Ethereum, you can also use ethminer to mine all tokens according to ethash algorithm, including expand, elaism, metaverse, musicoin, Pirl, Ethereum classic, etc< Ethminer is a command line software. This means that you can start it from the Linux console or the windows command prompt, or you can use the windows CMD / batch file or the Linux bash script to create a shortcut to the preset command line<

(2-cgminer)

this program was released in 2011. Because it is compatible with three different mining hardware (ASIC, FPGA and GPU), it is still one of the most popular mining software options. CG miner is an open source Ethereum miner written in C language, and provides support and binary files for openwrt router, RPI, etc

the advantages of cgminer include the ability to match your hash rate with zero latency extension, remote interface function and advanced detection of new blocks. The software can be used for Mac, Linux and windows

3 - Claymore (maximum efficiency)

if you are looking for the most efficient Ethereum mining software, please consider using Claymore's al Ethereum mining machine, which can speed up to any hash rate without sacrificing the mining speed

Claymore recently released v12.0 upgrade, which reces the equipment cost of al mining mode from 2% to 1%. The upgrade also offers 3gb and 2GB cards with zero development costs. However, Claymore al miner can't run on Mac. At present, it can only run on Linux and windows. But it supports both NVIDIA and AMD cards

other coins you can mine with this program include siacoin, lbry, decred and Pascal< If you are not familiar with cryptocurrency mining and are looking for the simplest Ethereum mining software, please check wineth

the software is based on the ethminer that we have just evaluated, but wineth provides users with a more simple and easy to understand GUI, combined with "intelligent" algorithm, which will provide the configuration that can ensure the best performance on the new user's hardware

as can be seen from the name, wineth is only compatible with windows devices, and you can find it in the windows 10 app store.

5. Tourism instry: triporg travel is a blockchain tourism service application, which can provide people with travel booking services such as train tickets and air tickets.

6. This can't really count. What is the output value of Shenzhen and how much is the richest man in Shenzhen; How much is the richest man in Longhua? It's conservatively estimated that it will cost at least 10 billion.

JCP mall is a mall that contains JCP operation mode. To understand JCP mall, we must first understand JCP

JCP maintenance specifications include J2ME, J2SE, J2EE, XML, OSS, Jain, etc. Organization members can submit JSR (Java specification requests) and enter the next version of the specification after passing a specific program

all J2EE procts (application server, application software, development tools, etc.) that claim to conform to the J2EE specification must pass the TCK compatibility test provided by the organization (need to purchase the test package), and after passing the test, they need to pay the J2EE trademark use fee. Two tasks are completed, that is, passing the authorized Java licenses of J2EE

JCP mall operation mode, you can learn about xiafangwei mall, which is convenient for you to understand xiaha
