What is Bitcoin mining? How to dig them like? 2021


What is bitcoin mining?

Currently, in the world bitcoin currency already quite popular, the appeal of this digital currency is shaking the e-commerce world. More and more bitcoin players, homes Bitcoin investment willing to spend hundreds of millions or even a few billion to "feed" these bitcoin mining rig, making a huge profit from this bitcoin mining.

What is bitcoin mining?

Bitcoin mining, plowing bitcoin also known as Bitcoin mining (English is Bitcoin Mining) is a term that describes the process of processing and confirming payments quickly on the bitcoin network.

Thus, it can be said that mining bitcoin is using a computer to detect BTC. This term reminds us of gold mining. Plowing bitcoin is like digging for gold, a miner needs intelligence, experience, time and, most importantly, persistence.

Bitcoin mining is implemented by an application installed on the computer so anyone can participate in the bitcoin mining system.

After a period of digging on traditional computers, some companies around the world have created hardware specifically for Bitcoin mining, which facilitates significantly faster block creation and transaction processing, increasing efficiency than conventional bitcoin plowing. To confirm the transaction and mount on blockchain chain, the dedicated bitcoin plow Must solve particularly complex cryptographic problems.

What is bitcoin mining?

Why is it called bitcoin mining? 

It is called that because this is the process for you Mining new Bitcoin from the system. But to put it more correctly, the exploit is just part of the transaction validation process.

Because you see the main goal of mining is to maintain the ledger in a decentralized way. Because the exploit is based on a form of decoding. Each time a different miner decodes and is granted the right to update the blockchain.

Of course, miners with more computing power will succeed more often. But due to the law of probability, it is very unlikely that the same operator will succeed at all times.

How to participate in bitcoin mining

Anyone who wants to participate in updating the ledger of Bitcoin transactions, called Blockchain, can do so.

All you need to do is guess a random number, solve the system-generated equation. This is done by your computer. The stronger your computer is, the more predictions you have in a second, increasing your chances of winning.

If you guessed it right, you will earn bitcoins and be able to write more about Bitcoin's transactions on the blockchain. The solution to the equation is difficult to achieve but very easy to confirm.

How does bitcoin mining work?

Miners are rewarded with a new bitcoin service every 10 minutes.

Many Bitcoin transactions occur at the same time. These transactions are included in the block. It is these blocks that Bitcoin miners have to verify. They verify transactions in blocks instead of verifying them individually.

Once a block is verified, it is added to a chain of previously verified blocks. That is why there is the technological concept behind bitcoin, blockchain.

How does the explanation for the blockchain technology behind bitcoin help people better understand the mining process? Now let's see how the exploit works:

How does bitcoin mining work?

I will explain the easiest for you to understand. For example, you are the one who exploits:

When your mining computer gives the right solution to a problem. Your computer will determine which pending transactions will be added to the next block of transactions on the blockchain.

You will now update the Bitcoin transaction ledger (or temporarily become the owner of that bitcoin). The transaction block you created, along with your solution, is sent to the entire network so that other computers can authenticate it. Each computer that confirms your solution updates the copy of the Bitcoin transaction ledger with the transactions you have chosen to include in the block.

The system generates a fixed amount of Bitcoin (currently 12.5 - will decrease over time). You should read more concepts Halving what? to understand the details offline. This is a reward for you for taking the time and energy to solve problems.

In addition, you are paid any transaction fees attached to the transactions you have inserted into the next block. All transactions in the block you have entered are currently validated by the Bitcoin network and are virtually irreversible.

So the end of a mining process already. While brief, there are many problems due to the value, the rarity and the difficulty of mining Bitcoin. I will give you some points about it later.

Difficulty level increases

The new sibling to the ecosystem of bitcoin mining and thought it was a free currency. People who read through the process I mentioned above will think that now I need to register where to exploit, where to confirm transactions. But it's actually not that fast, it costs all of that, kkk.

The inventor of Bitcoin is Satoshi Nakamoto have established mining rules in such a way that the more the network is exploited, the higher the difficulty will be. Guessing the answer to the mathematical problem of exploitation is even more complicated.

In short, the difficulty of the mining process is to adjust itself according to the cumulative mining power that the network possesses. If more miners get involved, it will be harder to solve the problem. This is a difficulty in exploitation. However, there are several solutions to this problem.

Adjust the difficulty 

  • The hard part is adjusting itself to create a steady stream of new Bitcoin into the system. In a sense, this was done for control inflationary.
  • The simpler understanding is that miners with more powerful hardware will win the math. This also means you'll need to buy more expensive hardware (this explains the following section).

The following difficulty adjustment concept makes it hard for bitcoin to die:

  • Mining difficulty is set so that the average. A new block will be added every 10 minutes. For every 2016 blocks created (about 14 days), the difficulty is automatically refined by the network based on the capacity of the entire network. If it is less than 10 minutes, it will increase the difficulty. And over 10 minutes, it will lower the difficulty.
  • The goal is to keep the interval between newly created blocks 10 minutes. From March 3 to March 2014, the average number of noncees (which is the amount added to the hash block, which meets the difficulty level limits) that the miner has to hash test before creating the new block. increased from 3 billion to 2015 billion (Wikipedia reference data). Terrible is not it.

What is the cost of mining Bitcoin?

Let's see what is the cost of Bitcoin mining? The main costs associated with bitcoin mining are the first two. And for the latter I add a little more:

  • Computer hardware cost: For starters, the cost of Bitcoin mining hardware will be over 12 million (over 600 USD). And it will be a lot more expensive if you want to buy better hardware.
  • Electricity consumption: Bitcoin mining uses a lot of electricity. If electricity in your area is too expensive, you should consider it.
  • Space to use: cool place, the temperature in the room must be cool (use air conditioner, ventilation fan, ..).
  • Take care of your rig: To take care of you or your team needs basic abilities from installing Windows to installing software. Or it is necessary to know how to fix the basic errors, while high tech will need technical guidance. The time you spend with it is like 24/24.
  • Finally, if you are lucky, you have bitcoin, so try.

Mining pool

Mining bitcoin is like competition. Even if you own the best buffalo you still have a huge disadvantage compared to professional Bitcoin mining farms. That is the reason why the Mining pool was born.

Guide to dig bitcoin at home

I will give the idea of ​​the process if you want to start mining bitcoin:

Step 1: Calculate profit 

Digging without profit, then do nothing to dig. Before getting started with Bitcoin mining, you need to research a few things. The best way is to discuss what happened. You should participate in learning from the community. Or learn from experienced people

Mining bitcoin is expensive, you should keep this in mind. If you don't have a lot of assets to use for your mining rig. Or do not calculate the cost of cheap electricity, do not think about mining bitcoin.

Next is to own yourself a mining rig:
