What is mining pool

What is mining pool?

n the context of cryptocurrency mining, a mining pool is the pooling of resources by miners, who share their processing power over a network, to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A "share" is awarded to members of the mining pool who present a valid partial proof-of-work. Mining in pools began when the difficulty for mining increased to the point where it could take years for slower miners to generate a block. The solution to this problem was for miners to pool their resources so they could generate blocks more quickly and therefore receive a portion of the block reward on a consistent basis, rather than randomly once every few years.

    How exactly does a mining pool work?

    In the context of cryptocurrency mining, a mining poolis the pooling of resources by miners, who share their processing power over a network, to split the reward equally, according to the amount of work they contributed to the probability of finding a block.

    What is a share in mining?
    share is merely an accounting method to keep the miners honest and fairly divide any rewards earned by the pool. There is no need to keep track of sharesin solo mining because you will not split the reward and can't cheat yourself. Usually pools use a difficulty of 1 as the target for a share.

    What is a block in mining?
    Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.

    What is a mining GPU?
    Graphics cards, or graphics processing units (GPUs), are more effective at miningthan CPUs and as Bitcoin gained popularity, GPUs became dominant. Eventually, hardware known as an ASIC, which stands for Application-Specific Integrated Circuit, was designed specifically for mining bitcoin.

    What is Cloud Mining for Bitcoin?
    Cloud Mining is the process of bitcoin mining utilizing a remote datacenter with shared processing power. This type of cloud mining enables users to minebitcoins or alternative cryptocurrencies without managing the hardware.

    What is a Bitcoin pool server?
    Bitcoin mining pools are a way for Bitcoin miners to pool their resources together and share their hashing power while splitting the reward equally according to the amount of shares they contributed to solving a block.

5 steps to start bitcoin mining

5 ways to start bitcoin mining




One of the biggest problems I ran into when I was looking to start mining Bitcoin for investment and profit was most of the sites were written for the advanced user. I am not a professional coder, I have no experience with Ubuntu, Linux and minimal experience with Mac. So, this is for the individual or group that wants to get started the easy way. 1.                     Get a Bitcoin mining rig Bitcoin mining is a very competitive niche to get into. As more and more miners come on board with the latest mining hardware the difficulty to mine increases each day. Before even starting out with Bitcoin mining you need to do your due diligence. This means you need to find out if Bitcoin mining is even profitable for you. The best way to do this is through the use of a Bitcoin mining calculator. Just enter the data of the Bitcoin miner you are planning on buying and see how long it will take you to break even or make a profit. However, I can tell you from the get go that if you don’t have a few hundred dollars to spare you probably won’t be able to mine any Bitcoins. Once you’ve finished with your calculations it’s time to get your miner. Make sure to go over our different Bitcoin mining hardware reviews to understand which miner is best for you. Today, the Antminer S9 is the newest and most powerful miner.

2.               Get a Bitcoin wallet First thing you need to do is get a “Bitcoin Wallet“. Because Bitcoin is an internet based currency, you need a place to keep your Bitcoins. Once you have a wallet make sure to get your wallet address. It will be a long sequence of letters and numbers. Each wallet has a different way to get the public Bitcoin address but most wallets are pretty straight forward about it. Notice that you’ll need your PUBLIC bitcoin address and not your PRIVATE KEY (which is like a password for your wallet). If you’re using a self hosted wallet (i.e. you downloaded a program to your computer and are not using an internet based service) there’s one additional very important step. Make sure you have a copy of the wallet.dat file on a thumb drive and print a copy out and keep it in a safe location. You can view a tutorial on how to create a secure wallet here. The reason is that if you computer crashes and you do not have a copy of your wallet.dat file, you will lose all of your Bitcoins. They won’t go to someone else, they will disappear forever. It is like burning cash.





3.                 Find a mining pool Now that you have a wallet you are probably roaring to go, but if you actually want to make Bitcoin (money), you probably need to join a mining pool. A mining pool is a group of Bitcoin miners that combines their computing power to make more Bitcoins. The reason you shouldn’t go it alone is that Bitcoins are awarded in blocks, usually 12.5 at a time, and unless you get extremely lucky, you will not be getting any of those coins. In a pool, you are given smaller and easier algorithms to solve and all of your combined work will make you more likely to solve the bigger algorithm and earn Bitcoins that are spread out throughout the pool based on your contribution. Basically, you will make a more consistent amount of Bitcoins and will be more likely to receive a good return on your investment. When choosing which mining pool to join you will need to ask several questions: What is the reward method? – Proportional/Pay Per Share/Score Based/PPLNS What fee they charge for mining and withdrawal of funds? How frequently they find a block (means how frequently I get rewarded)? How easy it is to withdraw funds? What kind of stats they provide? How stable is the pool? To answer most of these questions you can use our best Bitcoin mining pools review or this excellent post from BitcoinTalk. You can also find a complete comparison of mining pools inside the Bitcoin wiki. For the purpose of demonstration I will use Slush’s Pool when mining for Bitcoins. Once you are signed up with a pool you will get a username and password for that specific pool which we will use later on. Follow the link to go to their site and click the “Sign up here” link at the top of their site and follow their step by step instructions. After you have your account set up, you will need to add a “Worker”. Basically, for every miner that you have running, you will need to have a worker ID so the pool can keep track of your contributions.




4.                  Get a mining program for your computer Now that you’ve got the basics covered we’re almost ready to mine. You will need a mining client to run on your computer to that you will be able to control and monitor your mining rig. Depending on what mining rig you got you will need to find the right software. Many mining pools have their own software but some don’t. You can find a list of Bitcoin mining software here. I’m using a mac so I will use a program called MacMiner. The most popular program I’ve found for a PC are BFGMiner and 50Miner  . If you want to compare different mining software you can do this here.




5.                          Start mining OK, so hopefully now everything is ready to go. Connect you miner to a power outlet and fire it up. Make sure to connect it also to your computer (usually via USB) and open up your mining software. The first thing you’ll need to do is to enter your mining pool, username and password. Once this is configured you’ll basically start mining for Bitcoins. You will actually start collections shares which represent your part of the work in finding the next block. 


According to the pool you’ve chosen you will be paid for your share of coins – just make sure that you enter your address in the required fields when signing up to the pool. Here’s a full video of mining in action









Conclusion – perhaps it’s better just to buy the coins? To conclude this article here’s something to consider. Perhaps it would be more profitable for you to just buy Bitcoins with the money you plan to spend on Bitcoin mining. Many times just buying the coins will yield a higher ROI (return on investment) than mining. If you want to dig into this a bit deeper here’s a post about exactly that.


What is Bitcoin Mining?

What is Bitcoin Mining?






















One of the fundamental questions many people have about Bitcoin revolves around the tokens themselves. Questions about its value, security and history, all eventually lead to one place: Where do bitcoins come from?

While traditional money is created through (central) banks, bitcoins are “mined” by Bitcoin miners: network participants that perform extra tasks. Specifically, they chronologically order transactions by including them in the Bitcoin blocks they find. This prevents a user from spending the same bitcoin twice; it solves the “double spend” problem.
Skipping over the technical details, finding a block most closely resembles a type of network lottery. For each attempt to try and find a new block, which is basically a random guess for a lucky number, a miner has to spend a tiny amount of energy. Most of the attempts fail and a miner will have wasted that energy. Only once about every ten minutes will a miner somewhere succeed and thus add a new block to the blockchain.
This also means that any time a miner finds a valid block, it must have statistically burned much more energy for all the failed attempts. This “proof of work” is at the heart of Bitcoin’s success.
For one, proof of work prevents miners from creating bitcoins out of thin air: they must burn real energy to earn them. And two, proof of work ossifies Bitcoin’s history. If an attacker were to try and change a transaction that happened in the past, that attacker would have to redo all of the work that has been done since to catch up and establish the longest chain. This is practically impossible and is why miners are said to “secure” the Bitcoin network.
In exchange for securing the network, and as the “lottery price” that serves as an incentive for burning this energy, each new block includes a special transaction. It’s this transaction that awards the miner with new bitcoins, which is how bitcoins first come into circulation. At Bitcoin’s launch, each new block awarded the miner with 50 bitcoins, and this amount halves every four years: Currently each block includes 12.5 new bitcoins. Additionally, miners get to keep any mining fees that were attached to the transactions they included in their blocks.
Anyone can become a Bitcoin miner to try and earn these coins. However, Bitcoin mining has become increasingly specialized over the years and is nowadays mostly done by dedicated professionals with specialized hardware, cheap electricity and often big data centers.
To mine competitively today, you need to know what you’re doing, you must be willing to invest significant resources and time, and — last but not least — you need access to cheap electricity. If you have all of this, you too can give it a shot and become a Bitcoin miner.

What is Bitcoin?               




Bitcoin is a cryptocurrency and worldwide payment system.[10]:3 It is the first decentralized digital currency, as the system works without a central bank or single administrator.[10]:1[11] The network is peer-to-peer and transactions take place between users directly, without an intermediary.[10]:4 These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto[12] and released as open-source software in 2009.[13]
Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,[14] products, and services. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.[15]Research produced by the University of Cambridge estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.[16]

To cut through some of the confusion surrounding bitcoin, we need to separate it into two components. On the one hand, you have bitcoin-the-token, a snippet of code that represents ownership of a digital concept – sort of like a virtual IOU. On the other hand, you have bitcoin-the-protocol, a distributed network that maintains a ledger of balances of bitcoin-the-token. Both are referred to as “bitcoin.”
The system enables payments to be sent between users without passing through a central authority, such as a bank or payment gateway. It is created and held electronically. Bitcoins aren’t printed, like dollars or euros – they’re produced by computers all around the world, using free software.
It was the first example of what we today call cryptocurrencies, a growing asset class that shares some characteristics of traditional currencies, with verification based on cryptography.
Who created it?
A pseudonymous software developer going by the name of Satoshi Nakamoto proposed bitcoin in 2008, as an electronic payment system based on mathematical proof. The idea was to produce a means of exchange, independent of any central authority, that could be transferred electronically in a secure, verifiable and immutable way.
To this day, no-one knows who Satoshi Nakamoto really is.
In what ways is it different from traditional currencies?
Bitcoin can be used to pay for things electronically, if both parties are willing. In that sense, it’s like conventional dollars, euros, or yen, which are also traded digitally.
But it differs from fiat digital currencies in several important ways:
1 – DecentralizationBitcoin’s most important characteristic is that it is decentralized. No single institution controls the bitcoin network. It is maintained by a group of volunteer coders, and run by an open network of dedicated computers spread around the world. This attracts individuals and groups that are uncomfortable with the control that banks or government institutions have over their money.
Bitcoin solves the “double spending problem” of electronic currencies (in which digital assets can easily be copied and re-used) through an ingenious combination of cryptography and economic incentives. In electronic fiat currencies, this function is fulfilled by banks, which gives them control over the traditional system. With bitcoin, the integrity of the transactions is maintained by a distributed and open network, owned by no-one.






2 – Limited supplyFiat currencies (dollars, euros, yen, etc.) have an unlimited supply – central banks can issue as many as they want, and can attempt to manipulate a currency’s value relative to others. Holders of the currency (and especially citizens with little alternative) bear the cost.
With bitcoin, on the other hand, the supply is tightly controlled by the underlying algorithm. A small number of new bitcoins trickle out every hour, and will continue to do so at a diminishing rate until a maximum of 21 million has been reached. This makes bitcoin more attractive as an asset – in theory, if demand grows and the supply remains the same, the value will increase.
3 – PseudonymityWhile senders of traditional electronic payments are usually identified (for verification purposes, and to comply with anti-money laundering and other legislation), users of bitcoin in theory operate in semi-anonymity. Since there is no central “validator,” users do not need to identify themselves when sending bitcoin to another user. When a transaction request is submitted, the protocol checks all previous transactions to confirm that the sender has the necessary bitcoin as well as the authority to send them. The system does not need to know his or her identity.
In practice, each user is identified by the address of his or her wallet. Transactions can, with some effort, be tracked this way. Also, law enforcement has developed methods to identify users if necessary.
Furthermore, most exchanges are required by law to perform identity checks on their customers before they are allowed to buy or sell bitcoin, facilitating another way that bitcoin usage can be tracked. Since the network is transparent, the progress of a particular transaction is visible to all.
This makes bitcoin not an ideal currency for criminals, terrorists or money-launderers.
4 – ImmutabilityBitcoin transactions cannot be reversed, unlike electronic fiat transactions.
This is because there is no central “adjudicator” that can say “ok, return the money.” If a transaction is recorded on the network, and if more than an hour has passed, it is impossible to modify.
While this may disquiet some, it does mean that any transaction on the bitcoin network cannot be tampered with.
5 – DivisibilityThe smallest unit of a bitcoin is called a satoshi. It is one hundred millionth of a bitcoin (0.00000001) – at today’s prices, about one hundredth of a cent. This could conceivably enable microtransactions that traditional electronic money cannot.
