What is Bitcoin Mining?

Currently, in the world bitcoin coin already quite popular, the attraction from this digital currency is shaking the world of e-commerce. More and more people are playing bitcoin, folks bitcoin investment willing to spend hundreds of millions or even a few billion dong to "feed" these people bitcoin mining rigs, making huge profits from this bitcoin mining.

What is Bitcoin Mining?

bitcoin mining, plow bitcoin also known as Bitcoin Mining (English is Bitcoin Mining) is a term that describes the fast processing and confirmation of payments on the bitcoin network.

Thus, it can be said that bitcoin mining is the use of computers 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, perseverance.

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

After a period of mining activities on traditional computers, a number of companies around the world have created hardware specifically for mining. bitcoin mining, which supports significantly faster block generation and transaction processing, increasing efficiency over conventional bitcoin mining. To confirm the transaction and mount on blockchain chain, the dedicated bitcoin plow must be able to solve particularly complex cryptographic problems.

What is Bitcoin Mining?

Why is it called bitcoin mining? 

It's called that because it's the process that helps you Mining new Bitcoins from the system. But to be more precise, the mining part is only part of the transaction confirmation process.

As you see the main goal of mining is to maintain the ledger in a decentralized way. Since mining is based on a form of decryption. Each time a different miner decrypts and is granted permission to update the blockchain.

Of course, miners with more computing power will succeed more often. But due to the law of probability, it is highly unlikely that the same miner will be successful every time.

How to join bitcoin mining

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

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

If you guess correctly, you will earn bitcoins and can continue writing about Bitcoin transactions on the blockchain. The solution to the equation is very difficult to achieve but very easy to confirm.

How does bitcoin mining work?

Miners are paid a reward for their service of new bitcoins every 10 minutes.

Multiple Bitcoin transactions happening at the same time. These transactions are included in the block. It is these blocks that Bitcoin miners must verify. They verify transactions in blocks rather than verifying them individually.

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

The explanation for the blockchain technology behind bitcoin will help people better understand how mining works? Now let's see how mining works:

How does bitcoin mining work?

I will make it as simple as possible for you to understand. With the main example you are the miner:

When your mining computer gives the correct solution to a problem. Your computer determines which pending transactions should be added to the next block of transactions on the blockchain.

Now it is you who will 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 other computers can validate it. Each computer validating your solution updates its 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? for details. This is your reward for the time and energy you put into solving the problem.

In addition, you are paid any transaction fees attached to the transactions you inserted in the next block. All transactions in the block you just entered are now confirmed by the Bitcoin network and are virtually irreversible.

That's the end of a mining process. Although it is brief, it creates a lot of problems because the value, rarity, and difficulty of Bitcoin mining increases. I will review it for you guys a little bit about it in the next section.

Difficulty increased

I'm new to the bitcoin mining ecosystem and thought it was a free coin. People who briefly read the process I mentioned above will think that now I need to register where to mine, where to confirm transactions. But it's not really that fast, it costs all that stuff, kkk.

Inventor of Bitcoin is Satoshi Nakamoto built the mining rules in such a way that the more the network mines, the higher the difficulty increases. It is more complicated to guess the answer to the mining math problem.

In short, the difficulty of the mining process is self-regulating according to the accumulated mining power that the network possesses. If more miners are involved, it will be harder to solve the problem. This is the difficulty in exploitation. However, there are also some solutions to this problem.

Difficulty adjustment 

  • The difficulty here is to self-regulate to create a steady stream of new Bitcoins into the system. In a sense, this was done to control inflationary.
  • To put it simply, miners with more powerful hardware will win the computational solution. This also means that you will need to buy more expensive hardware (this will be explained later).

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

  • Mining difficulty is set to average. A new block will be added every 10 minutes. Every 2016 blocks are generated (about 14 days), the difficulty is automatically fine-tuned by the network based on the capacity of the entire network. If less than 10 minutes, it will increase in difficulty. For more than 10 minutes, it will lower the difficulty.
  • The purpose is to keep the interval between newly created blocks to 10 minutes. From March 3 to March 2014, the average number of nonce (the number added to the block hash that meets the difficulty limits) that miners had to test hash before generating a new block was increased from 3 billion billion to 2015 billion billion (Wikipedia Reference). Terrible, isn't it?

What does Bitcoin mining cost include?

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

  • Computer Hardware Cost: For starters, the cost of Bitcoin mining hardware will be over 12 million VND (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 think twice.
  • Use space: Cool place, room temperature to keep the machine cool (use air conditioner, exhaust fan, ..).
  • Take care of your system: To take care of you or your team, you need to have basic ability from installing windows to installing software. Or you have to know how to fix basic errors, and if you are highly technical, you will need technical guidance. The time you spend on it is like 24 hours a day.
  • Finally, if you are lucky, you have bitcoins, so try it.

Mining pool

Bitcoin mining is like a competition. Even if you have the best buffalo, you are still at a huge disadvantage compared to professional Bitcoin mining farms. That's why Mining pool was born.

Instructions for mining bitcoin at home

I will give an idea according to the process if you want to start mining bitcoin:

Step 1: Calculate profit 

Digging without profit, what's the point of digging? Before you get started with Bitcoin mining, you need to research a few things. The best way is to discuss the problem. You should participate in learning from the community. Or learn from someone who has gone before

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

Next is owning a mining rig:
