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 blockchain as it is a chain of blocks.
The blockchain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the blockchain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
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 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 transaction fees as well as a subsidy of newly created coins, called block rewards. 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.
In the early days of Bitcoin, anyone could find a new block using their computer’s CPU. As more and more people started mining, the difficulty of finding new blocks increased greatly to the point where the only cost-effective method of mining today is using specialized hardware.
To mine bitcoins, you need to acquire or build a bitcoin mining rig. Bitcoin mining rigs are special computers that solve the complex math problems necessary to mine bitcoins.
As more miners join the network, the difficulty of finding new blocks increases. The Bitcoin network adjusts the difficulty of finding a new block every 2016 block, or approximately every two weeks. It takes about 10 minutes to find a new block.
Bitcoin miners are rewarded for verifying and committing transactions to the blockchain. They are rewarded with transaction fees and a new Bitcoin block reward. The current block reward is 25 bitcoins. This halves every 210,000 blocks.
The block reward started at 50 bitcoins in 2009 and is now 25 bitcoins. Miners are currently rewarded with 12.5 bitcoins for every block mined. This halves every 210,000 blocks.
The best way to find out when that will happen is to watch the number of blocks found per day.

What are Bitcoin Mining Contracts?
Bitcoin mining contracts are a way to get started in the Bitcoin mining process without having to own any of your own hardware. Basically, you pay someone else to do all the hard work for you and you reap the rewards.
How do Bitcoin Mining Contracts Work?
When you buy a Bitcoin mining contract, you are essentially renting mining hardware. The hardware is owned and operated by the mining company, and you receive a portion of the mined Bitcoins in return.
The contract length varies but is typically around two years. During that time, you will receive a portion of the Bitcoins mined by the hardware.
There are a few things to watch out for when buying a Bitcoin mining contract.
- Make sure you understand the contract terms.
- Make sure the company you are buying the contract from is reputable.
- Make sure the hardware is actually mining Bitcoins.
- Make sure the company is actually paying out.
- Go to a reputable Bitcoin mining contract provider, such as Genesis Mining.
- Enter the amount of Bitcoin you want to mine.
- Choose the contract length.
- Review the contract terms.
- Pay for the contract.
- Receive your mining hardware.
- Start mining Bitcoins!
How Bitcoin Mining Software Works
Bitcoin mining software is how you actually start the process of mining for bitcoins. It is a program that sits in the background and does all of the work necessary to keep track of the Bitcoin network and solve complex equations.
There are a few different programs out there that can be used, but the most popular is called CGminer. CGminer is a command-line program, which means you have to type in all of the commands to use it. This can be a bit of a challenge for beginners, but it is worth learning how to use it.
First, you need to download the software. You can find the latest version on the CGminer website. Once you have downloaded it, extract the files to a folder on your computer.
Next, open up the CGminer folder and find the file called cgminer.exe. Double-click on this file to open the program.
The first thing you need to do is to enter your Bitcoin mining pool information. This includes the URL of the pool, your username, and your password.
Next, you need to choose the type of hardware you are using. If you are using an ASIC miner, choose the ASIC device. If you are using a GPU, choose the GPU device.
Finally, click on the Start button to start mining.
CGminer can be a bit of a challenge to use at first, but with a bit of practice, it becomes easy. Here are a few tips to help you get started:
-Make sure you are using the latest version of CGminer.
-Make sure you are using the correct type of hardware for your miner.
-Enter your mining pool information correctly.
-Be patient. It may take a while for your computer to solve the equations.
