What is Bitcoin Mining?

Bitcoin mining refers to the process of digitally adding transaction records to the blockchain, which is a publicly distributed ledger holding the history of every bitcoin transaction. Mining is a record-keeping process executed through immense computing power. Each Bitcoin miner around the world contributes to a decentralized peer-to-peer network to ensure the payment network is trustworthy and secure.

 

To securely add to the blockchain ledger, Bitcoin mining computers solve complex mathematical problems. When a solution is found, the latest block of confirmed transactions is added as the next link in the blockchain.

As an incentive to mine and contribute to the network, the miner who solved the problem is rewarded a block of Bitcoin.

The process of discovering new Bitcoin is described as mining because it resembles the process of mining for any other resource. With gold mining, miners search and dig through the earth in hopes of striking gold.

With Bitcoin, miners attempt to find Bitcoin through solving complex mathematical problems. Blockchain is the technology that cryptocurrency is built on. It is a ledger that is publicly distributed and records every Bitcoin transaction.

It is literally a digital chain of blocks. Each block contains a group of Bitcoin transaction information. Miners add to the blockchain by using computer processing power to solve complex mathematical problems. Solving the problems will result in the block being successfully added to the chain. The miner who correctly solves the problem is awarded Bitcoin.

The above forms the basis of the complex process of Bitcoin mining. It helps keep the payment network secure and trustworthy. The network is built on a peer-to-peer network, meaning that every single miner across the globe is contributing their computing power to maintain the network, confirm its transactions, and keep them secure.

 

10 Minutes per Block

Satoshi Nakamoto, the creator of Bitcoin, designed the Bitcoin network to allow for a block to be mined every 10 minutes. To maintain this 10-minute pace, the difficulty of the mathematical problems adjust automatically.

When there are more miners and more computing power attempting to mine, the level of difficulty will increase. When there are fewer miners and less computing power, the level of difficulty will decrease.

 

Evolution of Mining

At the beginning stages of Bitcoin in the early 2000s, individuals interested in Bitcoin mining were able to do so using their personal computers. As its popularity increased, so did the difficulty of mining.

To accommodate the growing level of difficulty, more computer processing power was required. Soon, miners used gaming computers to attempt to mine Bitcoin. The process repeated, and the mining difficulty and amount of computing power required increased.

Eventually, computers and chips were created for the sole purpose of mining Bitcoin. Today, it requires efficient hardware – those with strong computing abilities and energy efficiency.

Solving the Bitcoin algorithm to add to the blockchain and receiving Bitcoin requires an immense amount of electricity. Keeping electricity costs low is key to making Bitcoin mining profitable and sustainable.
