Essentials You Should Know About Bitcoin Mining – William Gaithersworth
Mining in the real world results in resources coming from the ground and being used to make items, buy items and more. Mining is an important part of any currency value.
The same is true with Bitcoin mining. Bitcoin mining is the main way that many people gain access to Bitcoins, but for anyone not familiar to Bitcoins, mining is a strange practice that they may not understand. To help everyone understand what is behind Bitcoin mining, here is a quick rundown of what you need to know to begin mining.
What Is It?
Simply put, Bitcoin mining is the process by which transaction records are added to the public ledger of Bitcoin. Past transactions are called blockchains and the blockchain helps to confirm transactions throughout the network that have taken place.
Mining is designed to be resource-intensive and difficult. This allows for the number of blocks found each day by Bitcoin miners to be steady. All individual blocks must contain some sort of proof of work in order for the blocks to be considered confirmed or valid. Bitcoin nodes will then verify each time that a block is received.
The purpose of the mining is to allow nodes in Bitcoins to reach a consensus that is considered secure and resistant to tampering. Mining introduces Bitcoins into the online system and anyone who mines are paid transaction fees and newly-minted Bitcoins.
Why Is It Called Mining?
No different than the mining of gold helps to create a currency that regulates the currencies of the world, Bitcoin mining does the same. Mining is a slow process in the real world that creates commodities.
Bitcoin mining is made to resemble the mining of other types of minerals like gold. It requires time and it slowly helps to create a new currency that is then available.
How Difficult Is It?
The reason that mining for Bitcoins is difficult is that the SHA-256 hash of a block’s header must be lower than, or at least equal to, the target. This has to be the case for the block to be accepted by the network.
To understand this better, a hash of a block must begin with a determined number of zeroes. The probability of actually calculating a hash that starts with a great deal of zeroes is actually extremely low. Many attempts to do this must be made, hence making it difficult.
The difficulty is a simple measurement of how hard it was to find the block, compared with how easy it can be at its very easiest. As more miners join in, the rate of block creation will increase. As that rate goes up, the difficulty goes up, which then pushes the block creation rate back down.
What Is The Reward?
Naturally, there is a reward for doing all this mining. When a block is finally found, the person who finds the block awards themselves Bitcoins, agreed upon by members of the network. The bounty is 25 Bitcoins right now, which will halve every 210,000 blocks. The miners are also awarded the fees paid by users.
How Do You Do It?
There are many ways that Bitcoins are mined by users. They include:
•GPU mining: This is more efficient than GPU mining because rather than use the CPU to process the calculations, the graphics processing unit is used. While a CPU core can do four 32-bit instructions per clock, a GPU will do 3200 32-bit instructions per clock.
•CPU mining: In the early days of mining, CPUs were mostly used to do the calculations. As the network grew and more efficient GPU mining began, the amount of Bitcoins produced by CPU mining went down. Today, it is generally disabled by default but can be enabled.
•FPGA mining: This is a very fast and very efficient way to mine, outperforming CPU mining and running along the same lines as GPU mining. FPGAs consume a small amount of power with huge hash ratings. FPGA stands for field-programmable gate array, which is an integrated circuit.
ASIC mining: The application-specific integrated circuit is a microchip designed for a specific need. ASICs designed for mining were first released in 2013. Using very little power, they have already made GPU mining unwise in some countries because of how fast and how efficient they are.
If you don’t want to do the mining yourself, you do have the option of mining services. There are mining contractors out there who will handle mining services based on a contract. Typically, you will rent out a specific level of capacity for a set time and a set amount. There is a risk for the system of Bitcoins with mining services.
The feeling is that they undermine the security assumption that mining power is distributed evenly. If too many large providers control the mining through consolidation, and an attacker compromises a provider, it could cause a huge disruption of the Bitcoin system.
There are also mining pools so that miners with limited supplies can work together and receive rewards for their efforts.
Best Software for Mining
There are several software packages out there for mining, but by far the best are these five:
•BitMinter: With the goal of making it easier for anyone to make Bitcoins, it helps the system process transactions and your computer takes part in the work, earning a share of the rewards.
•CGMiner: A multi-threaded multi-pool GPU miner, this one is very popular because of how simple it is.
•DiabloMiner: Distributed for free so others can find it useful, there is the risk because there is no warranty associated with the software.
•BFGminer: Written in C and featuring dynamic clocking, monitoring and remote interface abilities, it is an ASIC/FPGA miner.
•Poclbm: A python program script, it uses Bitcoins using an Open CL device.
Fees and Changes Currently, the processing fees of Bitcoin payment through mining are much, much lower than fees seen with money transfers and credit cards. As has been stated, reward for newly minted bitcoins are 25 per mined block.
To claim the reward, the miner puts a coinbase into the transaction block, which includes the address of the miner who is getting the reward. In 2019, the block reward falls down to 12.5 Bitcoins.
That number will fall again every four years from that point on. It is estimated that by 2140, there will be 21 million Bitcoins in existence.
