# <center>Introduction</center>

Crypto Currency Mining is basically the process whereby a computer/machine performs a task and earns crypto currency. It also means solving cryptographic equations through the use of computers. These tasks involves the process of verifying or validating crypto transactions by solving mathematical equations and inserting them in the blockchain.

# <center>How Mining Works</center>

**Nodes Verify The Legitimacy Of Transactions:**
A miner is a node in the network that collects and organises transactions into the blockchain. For each transaction that  takes place, all network nodes receives them and verify their validity.

**Adding A Separate Transactions To A List Of Other Transactions To Form A Block:**
After the verification process is completed, the next is to bundle all transactions into a list which is in turn added to a new unconfirmed block of data. Verified transactions added to the blockchain helps in keeping a permanent public record thereby preventing double spending. The records cannot be manipulated upon.

**Adding A Hash And Other Data To The Unconfirmed Block:**
Transactions are added to the block and additional transactions are added as well, which includes the header data and hash from both new and previous blocks.

Basically, the header of the most recent block and nonce are combined to generate new hash. This hash gets added to the unconfirmed block and will then need to be verified by miner nodes.

**Miners Verifies Block's Hash For Legitimacy:**
Here other Miners in the network Verifies the unconfirmed block by checking the hash.

**The Blocks Gets Confirmed and Published In The Blockchain:**
Here, the Proof Of Work is completed. The POW is the time consuming process of solving the hash. When the Miners process that the other party has legitimately done so, others can now verify after which the recently confirmed block gets inserted at the end of the blockchain.

Basically, the process of mining requires miners to keep hashing the block header over and over again, by iterating through the nonce until one of the network miner eventually produces a valid block hash. Then when a valid hash is found, the founder mode will broadcast the block to the network. All other nodes will verify the validity of the harsh, then add to the block in their copy of the blockchain.

Mining difficulty can be seen as how difficult and time consuming it is to find the right hash for each block. It is also a measurement unit used in the process of bitcoin mining. It indicates how difficult it could be solving a complex cryptographic task.

Mining difficulty is automatically adjusted after every 2,016 blocks had been mined in the network. The adjustment of difficulty upwards or downwards is dependent on the number of participants in the mining network and their combined hashpower.

# <center>Challenges Of Crypto-currency Miners</center>
Before now, crypto currencies could be mined with personal computers, but the reversed is the case now. Theoretically, each crypto has it's own block time. It takes Bitcoin about 10 minutes, while Etherium takes 20 seconds. With this statistics, single computer is disadvantaged. So miners are forced to adopt faster processors, miners now adopt a special machine known as Application Specific Integrated Circuit (ASIC).

**High Energy Cost:**
Just to solve a particular task, hundreds of ASICs are needed to maximize a successful Mining chances. As a result of this, extreme high power output is needed which will lead to a high electricity fees.

**Centralization of the Mining Space:**
There are very few ASICs manufacturers, so this might lead to centralization of the mining space. This is because ASICs had proven to mine solely a specific crytpo currency, and once a coin's ASIC is released, it's sometimes challenging to mine without one.  Basically, many crypto miners are influencing the way and manner in which ASICs are being created or designed, which can lead to the Centralization of the Mining space.

**High Rate Of Cyber Thieves:**
Hackers are getting more sophisticated at stealing people's resources. Cyber Thieves are now adopting tactics to remotely mine crypto currency from people's computers. And all these are serious challenges.

Basically crypto mining involves a couple of rigorous solving of taska and validating of blocks. It has a whole lots of cost implications and energy consumption as well.

This is an introduction post to crypto currency mining. Basically, I will be making a couple of posts around crypto currency and related topics for a period of time.
