Nowadays, bitcoin is getting a lot of mainstream attention. Almost everyone is talking about it. While discussing bitcoin’s creation, the word ‘mining’ keeps coming up a lot. Sounds similar to mining coal, gold, or any other precious metal. But, bitcoin mining is a bit different. And how exactly?
Bitcoin mining doesn’t involve physical labor. The work involved is computational.
Gold or coal exist underground, and miners dig them out. Similarly, bitcoins by design exist within the Bitcoin network.
Miners dig/compute them out by successfully solving mathematical problems, and they use specialized hardware for unraveling these problems. At least, nowadays.
Before delving deeper into bitcoin mining, let’s try and understand what the blockchain family consists of.
Bitcoin Nodes
Bitcoin Core is a software that is the driving force behind the Bitcoin network a.k.a blockchain. This software when installed on a computer downloads the entire blockchain, which is around 330 GB in size!
Bitcoin’s blockchain is a decentralized public ledger that contains the record/’chain’ of all bitcoin transactions segregated into ‘blocks’.
Apart from miners, The Bitcoin blockchain has other participants – nodes. Nodes or full nodes as they are better known have the latest version of the Bitcoin Core software installed and the entire Bitcoin blockchain downloaded on their computers.
They distribute copies of the updated blockchain to more nodes and help keep the network decentralized and secure.
Full nodes maintain the blockchain and ensure that everyone stays with the ‘longest’ chain.
The Bitcoin blockchain also comprises of light nodes. Light nodes function minimally, by just holding information of only the previous blocks. They connect with other light nodes to further decentralize the network and need less power to operate.
As of date, there are around 10,500 nodes across the world.
Miners are nodes as well and are called mining nodes. They perform a different set of functions compared to others.
While the full nodes validate bitcoin transactions and broadcast their information across the network, mining nodes or miners verify transactions and put them in blocks. Full nodes then add these blocks to the blockchain.
It is important to know that transaction validation occurs before verification. Now that the family is introduced, let’s jump to the main topic of discussion!
What Exactly Happens in Bitcoin Mining?
Bitcoin mining essentially is mining blocks to add bitcoin transaction information. That’s where the effort is. Here’s what exactly happens.
Once the full nodes detect and validate a bitcoin transaction, they are ready to be verified and confirmed by the miners. Before they enter the blockchain.
Competition is an important aspect of the bitcoin mining ecosystem. Miners compete with their other bitcoin mining peers to ‘work’ and compile transactions in a certain block.
Hashing
The ‘work’ involves solving the mathematical puzzle called a ‘hash function’, and requires a significantly high computational power. This happens per the SHA (Secure Hashing Algorithm)-256 hashing algorithm that is native to Bitcoin.
Solving hash functions amounts to solving a bitcoin block. Every hash function requires input data to be solved. The input data can be of any size. In the context of bitcoin mining, the inputs are unconfirmed bitcoin transactions.
Miners utilize the transaction inputs along with a few other pieces of arbitrary inputs to combine them and arrive at a ‘hash’ or result beginning with a set number of zeros. To know more about hashes check out the video below:
Hashes in bitcoin mining start with 18 zeros. Hash functions/blocks in the Bitcoin blockchain take approximately 10 minutes to solve. After this, full nodes take the call on adding them to the blockchain.
The miner who solves the block first receives a set number of bitcoins as a reward for the work done. This is called ‘proof-of-work’ (PoW). The reward is reduced every four years through an inbuilt process called ‘halving’. The current block solving reward is 6.25 bitcoins.
Bitcoin Mining Difficulty
Bitcoin mining has an element of difficulty embedded in the process. The difficulty is the sole reason why miners have to constantly update their hardware (spend more money and increase computational power) to stay in the game.
Mining difficulty increases with more miners joining the network.
Since increasing mining difficulty increases the cost of producing bitcoin, miners have to sell their BTC to cover operational costs. But that’s a topic for some other time.
Over time, the rising difficulty has led miners to switch from GPUs (Graphics Processing Units) used in high-performance gaming PCs to ASIC miners.
BTC Mining Today
Over the years, bitcoin mining has blossomed into a billion-dollar industry. ASIC miners specifically designed to mine bitcoin are the backbone of this industry. These devices can solve Bitcoin’s SHA-256 hash functions much faster than GPUs.
Also, bitcoin mining has become a costly proposition and is no longer suitable for individuals. That’s why different miners over time contributed their computing power and formed mining pools. Some of the biggest BTC mining pools operating currently are:
- Antpool
- F2Pool
- Poolin
- SlushPool
This is an overview of bitcoin mining. Head over to Telegram groups of some bitcoin communities in India like IndiaBits, Bitcoin India, and WazirX to interact with the members there and know more about the uses of bitcoin including investing. Hope this primer will not let you ‘wonder’ about bitcoin’s creation process anymore.
Frequently Asked Questions
How Much Is 1 Bitcoin Worth Today?
Check out the current price of Bitcoin on the WazirX exchange. Bitcoin's value is primarily determined by its supply and demand in the market. Other elements have an impact on its worth. Its intrinsic value can also be calculated by calculating the average marginal cost of producing a Bitcoin at any given time, based on the block reward, electricity price, mining hardware energy efficiency, and mining difficulty.
How Can I Convert Bitcoins To Cash?
Bitcoin may be converted to cash in various ways, including crypto exchanges, Bitcoin ATMs, Bitcoin Debit Cards, and Peer to Peer Transactions. You may do this by using Bitcoin exchanges like WazirX. You may also sell Bitcoin for cash faster and more anonymously through a peer-to-peer marketplace.
What Is Bitcoin Used For?
Bitcoin was created as a means of sending money over the internet. The digital currency was designed to be a non-centralized alternative payment system that could be used in the same way as traditional currencies. Bitcoin is being used by an increasing number of businesses and individuals. This includes establishments such as restaurants, apartments, and law firms.
What Is Bitcoin And How Does It Work?
Bitcoin is decentralized digital money that may be bought, sold, and exchanged without an intermediary such as a bank. Bitcoin is based on a blockchain that is considered to be a distributed digital ledger. As the name suggests, blockchain is a linked database made up of blocks that store information about each transaction, such as the date and time, total amount, buyer and seller, and a unique identifier for each exchange. Entries are linked in chronological order to form a digital blockchain
How To Convert Bitcoin To Cash?
There are many ways of converting Bitcoin to cash, such as crypto exchanges, Bitcoin ATMs, Bitcoin Debit Cards, Peer to Peer Transactions. You can use cryptocurrency exchanges such as WazirX for this. Unlike typical ATMs, which allow you to withdraw money from your bank account, a Bitcoin ATM is a physical location where you may buy and sell Bitcoins using fiat currency. Several websites provide the option of selling Bitcoin in return for a prepaid debit card that may be used just like a standard debit card. You can sell Bitcoin for cash through a peer-to-peer platform in a faster and more anonymous manner.
How Does Bitcoin Technology Work?
The blockchain is the foundation of Bitcoin. It is a decentralized, distributed ledger that tracks the provenance of digital assets. The data on a blockchain can't be changed by design, making it a real disruptor in industries like payments, cybersecurity, and healthcare.

Is Bitcoin And Cryptocurrency The Same Thing?
Bitcoin is a cryptocurrency that was designed to facilitate cross-border transactions, eliminate government control over transactions, and streamline the entire process without third-party intermediaries. The absence of intermediaries has resulted in a significant reduction in transaction costs. Satoshi Nakamoto, the creator of Bitcoin, created the first cryptocurrency in 2008. It began as open-source software for money transfers. Since then, plenty of cryptocurrencies have emerged, with some focusing on specific fields.
