Bitcoin is a digital currency or digital cash which eliminates the traditional way of doing financial transactions through banks and financial institutions.


It is like a digital version of cash to buy products and services. Currently, the use of Bitcoins is very limited. Many countries have completely banned the use of bitcoins. While, even in countries where bitcoin is legal, very few shops accept it as a currency to exchange.

Bitcoin is like a virtual currency described as cryptocurrency. A bitcoin does not hold any value without encoded private codes. 

There is no transaction fee, transaction delays attach to it. It is a free moving digital currency.

In India, Bitcoin has started gaining popularity due to government initiative for cashless tractions, but it is still accepted by a fraction of people. Currently, there is no defined institution like RBI to regulate its functioning. Neither it is administered centrally or by any institute defined by the government. 

Also, the daily tractions between the various parties and individuals are managed by the technology called blockchain which is a public ledger for all transactions.

Let us understand the transaction using Bitcoin with an example:  
Mr A is feeling hungry and he decides to order a pizza. He places his order to Mr B who owns a pizza shop in the local market.   Mr A uses Bitcoin as his mode for making the payment. He sends the required Bitcoins digitally to Mr B’s account and signs the transactions with his private key to verify the transaction.   After the transaction is verified by the miners, the required Bitcoins is sent to B’s account. And Mr A’s transaction is also broadcast on all the other network participants which are known as nodes on the bitcoin blockchain.   Once, the bitcoin is processed after all the technical and business rules checks, Mr B gets a score, whether to process Mr A’s demand or not. Now, Mr B can unlock his account using his private key if he wishes to use his Bitcoin account.  

History of Bitcoin

Interestingly, nobody knows the exact origin. But it is said that Bitcoin was created in 2019 under the pseudonym Satoshi Nakamoto (nobody knows the real name). This could be just one individual or group of people; nobody knows anything about it.

Some guess it is originated from Japan due to its last name Nakamoto, while some feel it is from an English speaking country due to Satoshi’s mastery over English. He/They also published a white paper on Bitcoin.

The technology used in Bitcoin was not something new. These technologies were already there in the market for example chain of block technology invented by Stuart Haber and W. Scott for timestamping documents.

Also, it is said that the creator of Bitcoin got the inspirations from earlier digital cash systems in the market, though none of them became as popular as Bitcoin.          

DigiCash – This technology was founded by David Chaum, cryptographer and computer scientist. He made DigiCash as a privacy-oriented Solution. The company went bankrupt and the was the entire model was trashed.

B-Money – This was introduced by computer engineer Wei Dai. In B-money, it is proposed as proof of work system, like a distribution database where people can sign as proof.  This technology also never took off.

Bit Gold – Computer scientist, Nick Szabo introduced this technology. In Bit Gold, ledgers that would record the data were maintained as a proof of work operation. There is a lot of similarities seen between Bit Gold and Bitcoin, and there are also theories about Bit Gold being the precursor of Bitcoin.

In short, we can say that Bitcoin was not the original idea of the inventor. The technology was inspired by other digital cashless systems invented in the market. But Bitcoin technology became the most successful and acceptable among the people.

How does Bitcoin Work?

The part which most of people want to know. How whole this concept of Bitcoins exactly works?

Before we move into the process. Let us first understand the terms used in Bitcoins. So that it becomes easier to understand its actual working. Know more with our Bitcoin Course.


This is the trading symbol used in Bitcoin.


The transactions are known as a block which is chained to a code. This way a permanent record a created of each transaction which is available on the public ledger known as Blockchain.

Private and public keys

Every bitcoin wallet has both a public and a private key. Both the keys are required for making transactions and digital signature. These keys together provide proof of authorization of transactions.


Place where Bitcoins are stored like a cloud

Bitcoin miners

Bitcoin miners are basically members of the peer-to-peer platform. The members of these platforms individually/independently confirm the transactions taking place (within 10-20 minutes). These members/miners are paid in bitcoins for their efforts.  

The entire Bitcoin function depends upon two mechanisms.


A blockchain is a shared ledger which contains all the transactions and is accessible to everyone.

The transactions are grouped as blocks which are then coded/cryptographically secured during mining and are linked to each other.


Mining is a process in which each block has to be secured with a code.

The miners/ members of the peer group carry out this process of grouping and coding the blocks by solving complex algorithms. The miners in return get rewarded with bitcoins (known as block reward)

Mining is a continuous process.

Once the transactions are cryptographed, these tokens known as bitcoins can be easily exchanged in the market for purchasing/selling goods and services.

Let us summarize:   Bitcoin is technically an encrypted computer file (known as Bitcoins) stored in a digital wallet   People can easily exchange these Bitcoins for goods and services.   All transactions are recorded in public forum known as blockchain
