Key Words
To understand the principle of cryptocurrency mining, we first need to understand several key words closely associated with its mining.
These are the following names that comprehensively show how cryptocurrencies are actually mined.
Blockchain
This English term literally means "chain of blocks." Each block is a batch of transactions, and on the Bitcoin network a new block is added about every ten minutes. A block contains:
-
movements or transactions between addresses,
-
nonce - a number that miners keep changing until the block hash meets the target set by the network,
-
hash - a unique digital fingerprint calculated from the data in the block, including the hash of the previous block, which is what links the blocks into a chain.
Therefore, each block in the chain has its unique hash. And a hash that meets the target set by the network is what cryptocurrency miners try to find.
Miners
Miners aim to find a valid hash for the next block. To do so, they keep trying different nonce values until the block hash falls below the target set by the network. Either they succeed or not. Cryptocurrency mining is essentially a luck-based lottery from this perspective.
Once the miners successfully calculate the correct nonce, they also receive the correct hash of the entire block. As a reward, they receive a reward such as several Bitcoins.
The competition continues by focusing on the next block. This creates a chain of more blocks or data. Each block must be verified.
There is no regulatory authority in the world of cryptocurrencies, and all transactions are verified by other miners.
Demanding Mining
More miners naturally mean more competition for each block. To make it more difficult, the creator of Bitcoin, Satoshi Nakamoto, incorporated an autoregulatory mechanism into his source code that gradually increases the mining difficulty.
As a result, the mining of Bitcoin is getting more and more difficult regularly.
Today, mining Bitcoin and other cryptocurrencies is practically unprofitable in domestic conditions. The costs associated with electricity and necessary technical equipment have made cryptocurrency mining less accessible.

FAQ
What is a blockchain?
The term literally means "chain of blocks." Each block contains transactions between addresses, a nonce and a hash, and each block in the chain has its own unique hash.
What do cryptocurrency miners do?
They keep trying different nonce values until a block hash meets the target set by the network, which is essentially a luck-based lottery. A miner who finds the correct nonce gets a reward, such as several Bitcoins.
Why is Bitcoin mining getting harder?
Bitcoin's creator, Satoshi Nakamoto, built an autoregulatory mechanism into the source code that gradually increases the mining difficulty. More miners also mean more competition for each block.
Is cryptocurrency mining at home profitable?
Today it is practically unprofitable in domestic conditions, because of the costs of electricity and the necessary technical equipment.
Modern gold mining
Crypto mining is sometimes compared to actual gold mining. It's a fitting analogy.
Just like with actual gold, you need to be patient, invest in the mining process, and then hope that luck will eventually be on your side.
As one old Biblical quote goes, you need to "search for it like hidden treasure".
