Cryptocurrency Mining How does it work?

Cryptocurrency mining is a complex and important process that ensures the security of the blockchain network and creates new cryptocurrency coins, a process known as "mining" because it is difficult and rewarding, much like mining precious minerals. The main purpose of mining is to verify transactions, create new blocks of transactions, and add them to the blockchain.

Basic concept of mining Proof-of-Work (PoW)

The most common method of mining is Proof-of-Work (PoW), which is used by some cryptocurrencies such as Bitcoin and Ethereum (although Ethereum has recently moved to Proof-of-Stake). In this process, miners compete to solve complex mathematical problems.

The whole process works in several steps

Transaction collection : When someone makes a cryptocurrency transaction, those transactions are stored in a "mempool" or waiting list of transactions, from which miners collect the transactions and create a new block.

Cryptographic puzzle solving : Miners try to solve a complex mathematical puzzle for this new block. To solve this puzzle, they have to find a special number "nones", which when combined with the block information with a cryptographic hash function creates a specific pattern. This is essentially a "trial and error" method, where the miners' computers try out numerous nones in rapid succession.

Block verification and addition to the network : The miner who can find the correct solution first is the winner, and his solution is verified by other miners. If the solution is proven correct, the new block is added to the end of the blockchain.

Reward : The winning miner is rewarded with two things for completing this difficult task: a block reward and a transaction fee.

The more miners that join the network, the more computational power or "hash power" is added, which means that the system automatically makes the puzzle harder to solve in order to keep the block creation time constant.

Types of Mining

1. CPU Mining : This was used in the early days of cryptocurrency, mining was done using the central processing unit (CPU) of a regular computer. Today, it is very unprofitable because it is very slow and cannot compete with modern mining devices.

2. GPU Mining : Mining is done using a graphics processing unit (GPU), which is much more powerful than a CPU. A "mining rig" is built using several GPUs, which was especially popular for mining cryptocurrencies like Ethereum.

3. ASIC Mining : ASIC stands for "Application-Specific Integrated Circuit", which is a special type of chip that is designed only for a specific task, such as Bitcoin mining. ASIC miners are extremely powerful and consume a lot of electricity, making ASIC mining the current main method of Bitcoin mining.

4. Mining Pool : It is extremely difficult to find blocks individually or by "solo mining", so many small miners come together to form a "mining pool". They combine their computational power and if any pool member finds a block, the reward is divided in proportion to their combined contributions.

Proof-of-Stake (PoS) is an alternative to mining

The main weakness of the Proof-of-Work (PoW) method is that it consumes a lot of electricity and is harmful to the environment, a new method called Proof-of-Stake (PoS) has been developed to solve this problem.

PoS process : Instead of mining, "staking" is done, users "lock" their cryptocurrency coins in a special wallet. Through this, they get the opportunity to be selected to validate the network's transactions.

Election process : The more coins a user has staked, the higher their chances of being selected.

Reward : The selected user or "validator" validates the transactions and receives some new coins or transaction fees as a reward.

Final Words

The PoS method is much more environmentally friendly than PoW and can complete transactions faster, which is why many new cryptocurrencies are currently using the PoS method, and some major blockchains like Ethereum have migrated from PoW to PoS. Crypto mining is a fundamental part of the blockchain, it not only creates new coins but also helps keep the entire network secure and decentralized. Today's discussion concludes here.
