Bitcoin Mining Software Guide

While the actual process of Bitcoin mining is handled by the Bitcoin mining hardware itself, special Bitcoin mining software is needed to connect your Bitcoin miners to the blockchain and your Bitcoin mining pool as well, if you are part of a Bitcoin mining pool.

The software delivers the work to the miners and receives the completed work from the miners and relays that information back to the blockchain and your mining pool. The best Bitcoin mining software can run on almost any operating system, such as OSX, Windows, Linux, and has even been ported to work on a Raspberry Pi with some modifications for drivers depending on your mining setup.

Not only does the Bitcoin mining software relay the input and output of your Bitcoin miners to the blockchain, but it also monitors them and displays general statistics such as the temperature, hashrate, fan speed, and average speed of the Bitcoin miner.

There are a few different types of Bitcoin mining software out there and each have their own advantages and disadvantages, so be sure to read up on the various mining software out there.

Network Consensus

If you solo-mine, meaning you do not mine with a Bitcoin mining pool, then you will need to ensure that you are in consensus with the Bitcoin network. The best way is to use the official BitCore client.

If you participate in a Bitcoin mining pool then you will want to ensure that they are engaging in behavior that is in agreement with your philosophy towards Bitcoin.

How much bandwidth does Bitcoin mining take? If you are mining with a pool then the amount should be negligible with about 10MB/day. However, what you do need is exceptional connectivity so that you get any updates on the work as fast as possible.

For example, some rogue developers have threatened to release software that could hard-fork the network which would likely result in tremendous financial damage.

Therefore, it is your duty to make sure that any Bitcoin mining power you direct to a mining pool does not attempt to enforce network consensus rules you disagree with.

Bitcoin Wallet Software

The whole point of mining bitcoins is to earn them!

But once you earn them then where do you keep them safe and secure? For a Bitcoin wallet we highly recommend using one where you hold your own private keys in contrast to to a hosted wallet like Coinbase or Circle.

• Breadwallet - easy to use mobile Bitcoin wallet
• Copay - easy to use mobile Bitcoin wallet
• Armory - highly secure desktop Bitcoin wallet

You will also need to be able to buy and sell your Bitcoins.

Once mined Bitcoin becomes like a currency that can be purchased, used in transactions or even traded like with this Bitcoin trading platform.

For this we recommend:

• Kraken - The largest European exchange with same-day SEPA
• Local Bitcoins - This fantastic service allows you to search for people in your community willing to sell bitcoins to you directly. But be careful!

TRANSCRIPT - Do it yourself with Bitcoin mining software

What's going on every one? This is Fredand this Part 2 of our DIY Bitcoin Miner. Today, we're going to take a look at software.

Okay, so the first thing that you need to do before you could start Bitcoin mining is to sign up for a Bitcoin wallet. Now there’s a lot of wallets that you could choose from but I prefer Circle. Now let’s head over and set up an account. All you have to do is enter in your email and choose a password.

Once you log in to your account you will see a summary of your Bitcoin balance and transactions. But before you can receive any Bitcoins you need to set up a Bitcoin address. You could do so by clicking account settings.

Once you are on the account settings page go ahead and click Bitcoin Addresses. From there click Create New Address. This generates a long string of numbers and letters. This is the address that we will need to enter into our mining pool. So let's take a look at that now.

There are many mining pools that you can choose from, but I prefer BitMinter as my primary pool and Slush’s pool as my backup. Just create an account whichever one you choose and log in. Your account details page will normally have an auto cash out option.

This is where we will enter in our wallet address that we created earlier. When you have mined enough Bitcoins to meet the threshold it would automatically be transferred to your Bitcoin wallet.

Next, go up top to the My Account drop down and select Workers. This worker information is what you need to input into the mining software so that you get credit for the work that is done. You do not need to secure this information with a difficult username or password because anyone that uses this information will be giving you credit.

Now let's take a look at setting up the mining software. As mentioned in Part 1 of the series we'll be using the MinePeon operating system. This can be downloaded from sourceforge.net.

Now this is the image that we will need to write onto our SD card. Another software that we need to download is called the Win32 Disk Imager. This can also be found on sourceforge.net. This is the software that we will use to write the MinePeon image onto our SD card.

Once you have downloaded both files insert your SD card into your computer. Then open up Win32 Disk Imager. Simply select the location of your MinePeon image then select the correct drive for your SD card. All you have to do now is click write. This will write the MinePeon image on to your SD card. Insert the SD card into your Raspberry Pi as shown on Part 1 of the series then power up the unit.

Now sign in to MinePeon by typing in the network IP address into your browser. The easiest way to find this IP address is by logging in to your router and looking for the device called MinePeon. You will then be prompted to enter in your MinePeon's username and password. The default setting for this is MinePeon for the username, peon for the password. You will see a security warning but do not be alarmed. This is perfectly normal so proceed anyways. You will then be asked to re-enter the username and password.

So again, MinePeon is the username peon is the password. You are now finally in MinePeon's dashboard. This is where you can monitor the performance of your mining rig. Head up top and click pools. This page allows you to set up your mining pools. As you can see I have BitMinter as my primary pool and Slush’s pool as my secondary. Just enter in the URL of your mining pool, the username and password if you have one.

Then go ahead and submit your settings. You may need to reboot MinePeon after any changes. Great job every one. You are now officially mining for Bitcoins.

All right, so that should be everything that you need to start Bitcoin mining.

The Meaning of Bitcoin Mining Software

Assuming that you already have at least minor knowledge in Bitcoin Mining Hardware, we will now be tackling the best Bitcoin Mining Software. While they differ on process handling, both of them have the same importance in terms of Bitcoin mining.

If you are doing it by your own, the BTC mining software will then connect to your blockchain. Whereas, if you are mining with your buddies and using the pool, then your software will be connecting to a Bitcoin mining portal.

On the other hand, Bitcoin cloud mining doesn't need any mining software to use with.

Bitcoin Mining Software Importance

The actual process of Bitcoin mining is to connect both mining hardware and mining software. Hence, the Bitcoin mining software will take care of the distribution of digital data into the network and process them into a complete information for you to be able to understand the statistics.

You can then monitor the in and out of your miner device by displaying the information you want to show on screen. That includes hashrate, speed of the Bitcoin miner, fan speed and the temperature of the hardware.

BTC Wallets

Wallet is a MUST before using or doing any mining stuffs. Bitcoin address will be on the wallet that you can use when setting up the Bitcoin mining software. The purpose is to send the payouts and rewards in the future.

After you make and downloaded a wallet, that's the time you can have the address to supply on the Bitcoin mining software setup.

We can recommend you the following wallets :

Electrum - This wallet can work on multiple platforms like Windows, Linux and Mac.

Mycelium - This wallet is the most common wallet in Android.

Breadwallet - This wallet is the most common wallet for IOS.

If you have this high hope to profit more money in Bitcoin mining then purchasing a hardware wallet would be a good idea, which is more secure than the above wallets. You can also go to Ledger Nano S which priced in the market for $60 - $65 which will keep your coins more and more secure.

Since you already have the idea on what is a Bitcoin mining software is including the idea of a wallet, it's time to learn on different BTC software that runs on different platforms.

Bitcoin Mining Software

Now that you already know about the best Bitcoin mining hardware, we’re going to talk about Bitcoin mining software.

What is Bitcoin Mining Software?

Bitcoin mining hardware handles the actual Bitcoin mining process, but:

Bitcoin mining software is equally as important.

• If you are a solo miner: the mining software connects your Bitcoin miner to the blockchain.
• If you mine with a pool: the software will connect you to your mining pool.
• If you are cloud mining: you do not need mining software.

Importance of Bitcoin Mining Software

The main job of the software is to deliver the mining hardware’s work to the rest of the Bitcoin network and to receive the completed work from other miners on the network.

Bitcoin mining software monitors this input and output of your miner while also displaying statistics such as the speed of your miner, hashrate, fan speed and the temperature.

Bitcoin Wallets

One of the most important things you will need before using any kind of Bitcoin mining software is a wallet.

This is because all Bitcoin mining software will ask you for a Bitcoin address that will be used to send your mining rewards and payouts. Once you create or download a wallet you will be able to get a Bitcoin address from your wallet.

There are many Bitcoin wallets, but these are the ones we recommend if you are just starting out:

• Ledger Nano S – Secure Bitcoin hardware wallet for all platforms.
• Electrum – Simple Bitcoin wallet that works on Mac, Windows, and Linux.
• Mycelium – The most popular Bitcoin wallet on Android.
• breadwallet – The most popular Bitcoin wallet for iOS.

If you expect to earn a lot of money through mining then it would be smart to purchase a more secure wallet: a hardware wallet.Now that we understand mining software and how it helps in the mining process, and you got your Bitcoin wallet and address, let’s look at different software on different operating systems.

Bitcoin Mining Software for Windows

Bitcoin Miner

You can use Bitcoin Miner on Windows 10 and Windows 8.1.

It has an easy to use interface, power saving mode, mining pool support and fast share submission.

The 4 best Bitcoin mining software

Last updated on February 25th, 2018 at 01:24 pm

Are you thinking of joining the Bitcoin mining universe? In case you don’t know, you can either mine on your own or as part of a pool. In terms of profit, there aren’t really many differences: solo mining will give you large and irregular payouts, as pooled mining will result in small and frequent payouts. In the end, they both add up to the same amount.

Whatever your choice might be, remember you need to follow certain steps to successfully mine Bitcoins:

1. Get the right Bitcoin mining hardware. Today only ASIC miners are a viable option for mining Bitcoin.
2. Get the best software that matches your needs
3. Arrange a way to receive the profits of mining
4. Start solving algorithms.

This is where you stop and think: but what is the best software for me if I don’t even know them all? Well, let’s make a small list of the most used software and help you choose.

IMPORTANT – Software that doesn’t support ASIC mining should be ignored for mininig Bitcoin as you can only profit today if you use an ASIC miner.

This software is, currently, the most popular GPU/FPGA/ASIC miner. CGminer is an open source GPU miner written in C available for several platforms like Windows, Linux and OS X. One of the things that make it extremely popular is the fact that it’s based on the original code Cpu Miner, which you can discover in Bitcoin Wiki.

This software includes overclocking, monitoring, fans peed control and remote interface capabilities. His other features include self detection of new blocks with a mini-database, binary loading of kernels, multi GPU support and CPU mining support. There are a lot of other characteristics you can discover here, at CGminer official forum.

2. BFGminer

This software is a derivative of the previous CGminer, designed specifically for FPGA and ASICs, but without the central focus on GPUs like CGminer. The latest update on BFGminer, the 3.1.1 version launched in April 2012, features dynamic clocking, monitoring and remote interface capabilities.

Besides being a super versatile program, BFGminer has really interesting features: vector support, integrated overclocking and fan control, ADL device reordering by PCI bus ID, support for mining with free Mesa/LLVM OpenCL and for getblocktemplate decentralized mining protocol and also crypt mining support for both CPU and OpenCL (GPU).

A little reminder: if you’re mining with a ModMiner, X6500 or ZTEX devices, you need to download bitstreams to make sure BFGMiner 3+ works with your device. You can find them in the official BFGminer forum and check BFGminer’s official website here.

3. BitMinter

We can say that, although BitMinter might not be the most popular mining software, it’s certainly one of the best when it comes to connect with users and potential “clients”. The software’s official website is quite complete and straightforward: for the creators of the program, it’s all about making Bitcoin mining “easy” and winning “high payouts”.

BitMinter is different because it’s a software that belongs to a mining pool, so your initial step is to register and fill in the pool sign-up form. So, it’s a great option if you’re looking for a simple installation.

Besides being available for operative systems like Windows, Linux and Mac OS X, BitMinter assures a good mining speed and long polling in order to reduce stale work. It also allows you to mine on OpenCL-compatible GPUs or ASICs/FPGAs (BFL, Block Erupter and other Icarus-compatible). The official BitMinter forum can be found here.

4. BTCMiner

This open source Bitcoin mining software for ZTEX USB-FPGA Modules 1.15 runs on the operative systems Linux and Windows. Yet, Windows users need to install the libusb driver first, which you can find here. The FPGA boards supported by BTCMiner (USB-FPGA Modules 1.15b and 1.15d, USB-FPGA Modules 1.15x and USB-FPGA Modules 1.15y.) have a USB interface, which can be used for communication and programming, allowing the user to build low cost FPGA clusters with standard components (like USB hubs, for instance). In practical terms, this means no JTAG programmer is required and the program allows to run large mining rigs from just one software instance.

The software features a ready-to-use Bitstream, which doesn’t require any Xilinx Software or a license, so this is an advantage. However, its dynamic frequency scaling is based on error measurement: so, BTCMiner automatically chooses the frequency with the highest rate of valid hashes. You can find BTCMiner official website here and discover more about this mining software.

After presenting you these different software miners and its characteristics, it’s safe to say one thing: more important than rating them and placing them on a podium, you need to know them to correctly choose the one that’s better for your needs and already available hardware. If you’re looking for a technical comparison, check out our best Bitcoin mining hardware page. Good mining!

In the search for Anaïs Nin, one of the first few links shows a picture of a man. Why? Since Nin is a woman, I can’t figure out why. Can you show some reason for this? Who is he? If you click on the picture a group of pictures of Nin and no mention of that man. Is it an error?

Repair the Yahoo Search App.

Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.

I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.

I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and I signed in so he could try to fix the Yahoo Search App not working. He also used another phone, installed the app from the Google Play Store to see if the app would do any kind of search thru the app. The Yahoo Search App just wasn't working.

I also had At&t try to help me because I have UVERSE for my internet service. My internet was working perfectly. Their Technical Support team member checked the Yahoo Search App and it wouldn't work for him either.

We can go to www.yahoo.com and search for any topic or website. It's just the Yahoo Search App that won't allow anyone to do web searches at all.

I let Google know that the Yahoo Search App installed from their Google Play Store had completely stopped working on May 18, 2018.

I told them that Yahoo has made sure that their Yahoo members can't contact them about anything.

I noticed that right after I accepted the agreement that said Oath had joined with Verizon I started having the problem with the Yahoo Search App.
No matter what I search for or website thru the Yahoo Search App it says the following after I searched for
www.att.com.

WEBPAGE NOT AVAILABLE

I tried to search for things like www.homedepot.com. The same thing happened. It would say WEBPAGE NOT AVAILABLE. The only thing that changed were all the upper and lower case letters, numbers and symbols.
Then it would again say
could not be loaded because:
net::ERR_CLEARTEXT_NOT_PERMITTED

This is the same thing that happened when Samsung and At&t tried to do any kind of searches thru the Yahoo Search App.

Yahoo needs to fix the problem with their app.

How Bitcoin Mining Works

Where do bitcoins come from? With paper money, a government decides when to print and distribute money. Bitcoin doesn't have a central government.

With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.

Bitcoin is Secure

Bitcoin miners help keep the Bitcoin network secure by approving transactions. Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure.

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.

Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

What is Bitcoin Mining?

What is the Blockchain?

Bitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.

The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins.

This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.

Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.

What is Proof of Work?

A proof of work is a piece of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements. It must be trivial to check whether data satisfies said requirements.

Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated. Bitcoin uses the Hashcash proof of work.

What is Bitcoin Mining Difficulty?

The Computationally-Difficult Problem

Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network.

This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information.

The Bitcoin Network Difficulty Metric

The Bitcoin mining network difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. It is recalculated every 2016 blocks to a value such that the previous 2016 blocks would have been generated in exactly two weeks had everyone been mining at this difficulty. This will yield, on average, one block every ten minutes.

As more miners join, the rate of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless.

The Block Reward

When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve every 210,000 blocks. See Controlled Currency Supply.

Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.

What is Bitcoin?

Last updated: 26th January 2018

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 – Decentralization

Bitcoin'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 supply

Fiat 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 - Pseudonymity

While 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 - Immutability

Bitcoin 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 - Divisibility

The 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.

Read more to find out how bitcoin transactions are processed and how bitcoins are mined, what it can be used for, as well as how you can buy, sell and store your bitcoin. We also explain a few alternatives to bitcoin, as well as how its underlying technology – the blockchain – works.
