Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.
Business runs on information. The faster it’s received and the more accurate it is, the better. Blockchain is ideal for delivering that information because it provides immediate, shared and completely transparent information stored on an immutable ledger that can be accessed only by permissioned network members. A blockchain network can track orders, payments, accounts, production and much more. And because members share a single view of the truth, you can see all details of a transaction end to end, giving you greater confidence, as well as new efficiencies and opportunities.

The future of finance could be dominated by blockchain technologies. The future of security is in the blockchain because the current methods of keeping the data are not reliable enough. Blockchain is the revolutionary tech of the future, for future security aspirants, it will be the best for them to understand the working of blockchain.
Cryptocurrency is decentralized digital money that is based on blockchain technology and secured by cryptography. To understand cryptocurrency, one needs to first understand three terminologies – blockchain, decentralization, and cryptography.
In simple words, blockchain in the context of cryptocurrency is a digital ledger whose access is distributed among authorized users. This ledger records transactions related to a range of assets, like money, house, or even intellectual property.
The access is shared between its users and any information shared is transparent, immediate, and “immutable”. Immutable means anything that blockchain records is there for good and cannot be modified or tampered with – even by an administrator.
Centralized money refers to the regular money that we use, which is governed by authorities like the Reserve Bank of India. Decentralization in cryptocurrency means there is no similar authority that can be held responsible for supervising the rise and fall of a particular cryptocurrency. This has many benefits over centralized money.
Some of these benefits include the following:
There is no need for currency owners to “trust” a single governing entity, as everyone in the network has access to the same information that cannot be altered. Data remains accessible only to the users of the network and it is heavily secured. Shared ownership also means all users sign off on how accurate the data is, which means there is very little scope for data mismanagement or miscommunication. Think of it as a democracy. Security, which is a fundamental part of a blockchain. Cryptography is the method that secures data from unauthorized access by the use of encryption techniques. Most of the claims that blockchain makes, like privacy and immutability, are enabled through cryptography.
The roots of cryptocurrency technology can be traced back to the 1980s with the invention of what is called a “blinding algorithm”. The algorithm is all about secure and immutable digital transactions. It remains fundamental to the modern-day digital currency.
In 2008, a group of people (currently known under the pseudonym Satoshi Nakamoto) created the guiding principles of the first and leading cryptocurrency in the market today, Bitcoin. In 2009, Bitcoin was launched to the world. But it would be years before it was formally recognized as a means of payment among leading merchants, starting with WordPress in 2012.
The underlying blockchain technology is today used in banking, insurance, and other business sectors. Growing at a compounded annual growth rate of 12.8% since 2021, the cryptocurrency market is estimated to reach $4.94 billion by 2030, thanks to the need to improve the efficiency of today’s payment systems, rise in global remittances and increased need to secure data.
How Does Cryptocurrency Work?
Cryptocurrencies are not controlled by the government or central regulatory authorities. As a concept, cryptocurrency works outside of the banking system using different brands or types of coins – Bitcoin being the major player.
- Mining
Cryptocurrencies (which are completely digital) are generated through a process called “mining”. This is a complex process. Basically, miners are required to solve certain mathematical puzzles over specially equipped computer systems to be rewarded with bitcoins in exchange.
In an ideal world, it would take a person just 10 minutes to mine one bitcoin, but in reality, the process takes an estimated 30 days.
- Buying, selling, and storing
Users today can buy cryptocurrencies from central exchanges, brokers, and individual currency owners or sell it to them. Exchanges or platforms like Coinbase are the easiest ways to buy or sell cryptocurrencies.
Once bought, cryptocurrencies can be stored in digital wallets. Digital wallets can be “hot” or “cold”. Hot means the wallet is connected to the internet, which makes it easy to transact, but vulnerable to thefts and frauds. Cold storage, on the other hand, is safer but makes it harder to transact.
- Transacting or investing
Cryptocurrencies like Bitcoins can be easily transferred from one digital wallet to another, using only a smartphone. Once you own them, your choices are to:
a) use them to buy goods or services
b) trade in them
c) exchange them for cash
If you are using Bitcoin for purchases, the easiest way to do that is through debit-card-type transactions. You can also use these debit cards to withdraw cash, just like at an ATM. Converting cryptocurrency to cash is also possible using banking accounts or peer-to-peer transactions.
Types of Cryptocurrencies
There are tens of thousands of cryptocurrencies available today with the figure pegged at 10,000 in 2022. Major cryptocurrencies include the following:
Bitcoin Bitcoin is the world’s first widely accepted form of cryptocurrency. Bitcoin is so popular, there was a time when its name was synonymous with cryptocurrency. But potential investors need to know bitcoins have become very expensive. In 2021, the cost of one Bitcoin was $68,000. But the good news is, you don’t always have to buy an entire coin, you can buy smaller fractions of it.
Altcoin Altcoin is the term used for any alternative digital currency to bitcoin. The most popular in this ecosystem is Ethereum – one of the fastest-growing cryptocurrencies in the market. There is also a range of other altcoins in the market today such as Luckyblock, Shiba Inu and Terra.
Crypto tokens The concept of crypto coins vs tokens can be confusing to many. At first glance, coins and tokens appear the same. However, the two have many differences
Coins can be mined, but tokens cannot be mined. Coins are linked to blockchains, tokens are not. In terms of utility, they vary in the type of product or service they allow users to purchase.
