What is Cryptocurrency?
Cryptocurrencies are digital currencies secured by cryptographic algorithms and distributed among authorized users to verify the transactions. Unlike fiat currencies governed by the government, digital currencies are decentralized, enabling anyone to transfer digital payments securely to anyone, anywhere.
Cryptocurrencies are powered by three technologies primarily — Blockchain, Decentralized Ledger, and Cryptography. All cryptocurrency transactions are recorded in a distributed public ledger accessible to authorized users. Since no central authority governs the cryptocurrency transactions, miners validate the transactions by solving cryptographic algorithms.
Miners record the transactions on a public ledger upon verification. The transactions, once entered, cannot be altered, preventing double-spending while assuring secure transactions. Bitcoin was the first cryptocurrency that successfully leveraged blockchain technology for its decentralized nature. Now, almost all cryptocurrencies are backed by blockchain technology.
How does Cryptocurrency Work?
Cryptocurrencies run on a decentralized distributed ledger backed up by blockchain technology. The cryptocurrency transaction details are stored in chained blocks, linking blocks in chronological order. Thus, the data cannot be changed or tampered with as the change is reflected in all blocks.
Since no single authority governs cryptocurrency transactions, network participants, commonly known as miners, validate the transactions. Let’s break down the cryptocurrency transaction process for better understanding.
- Cryptocurrencies run on a distributed ledger accessed by a network of nodes globally. The miners on the nodes validate transactions to maintain the integrity and security of crypto transactions.
- Cryptocurrency transactions are stored in a block. Each block is linked to its previous block, forming a blockchain. In short, a blockchain is a public ledger with all transaction details across the network.
- The transactional data in the block is encrypted to an alphanumeric string called a hash. Miners should solve complex cryptographic problems to find the hash. Once they figure out the hash, the new block is added to the ledger.
- Crypto mining is a complex, energy-intensive process. Thus, the miner who solved the hash and added the new block will receive the freshly minted new cryptocurrencies for contributing their computational resources and technical expertise.
- Users can store their cryptocurrencies in digital wallets. There are several types of cryptocurrency wallets that you can choose from according to your preferences.
- The distributed ledger records transactions related to any digital assets ranging from cryptocurrencies to intellectual property, etc.
In summary, users can transfer cryptocurrencies to anyone without intermediaries. The crypto transactions are safe, secure, and immutable, saving time and cutting costs.
Key Features of Cryptocurrencies

Cryptocurrencies possess specific prime features that distinguish them from traditional currencies. Here are a few of them.
1. Decentralization
Cryptocurrencies run on a decentralized network of nodes distributed worldwide to verify and validate transactions. Thus, it eliminates the need for a central authority like a government managing them.
2. Anonymity and Privacy
Though all crypto transactions are recorded on the blockchain and are publicly accessible, the identity of users is not revealed anywhere. Users need not provide any personal information as they do with banks. Users are often identified with cryptographic addresses rather than personal details. Thus, no sensitive information is shared on the internet.
3. Immutability and Security
Once the cryptocurrency transactions are added to the blockchain, it cannot be altered or tampered with. The immutability ensures secure and reliable transactions without involving third parties.
4. Low-Cost Transactions
Cryptocurrency transactions are much faster and cheaper than traditional financial systems. For instance, cross-border transactions or international transactions of traditional currencies would cost a lot of money. However, you can transfer cryptocurrencies to anyone, anywhere in the world.
5. Volatility
Cryptocurrencies are notoriously volatile. Almost all cryptocurrencies undergo significant fluctuations in a short period. Though it poses a risk to investments, studying the market carefully and investing in the right assets can give a good Return on Investment(ROI).
6. Limited Supply
Most cryptocurrencies, from Bitcoin to Litecoin, undergo halving to create scarcity and maintain their price. Thus, many investors see cryptocurrency as a potential alternative investment like gold and real estate and use it as a hedge against inflation due to its limited supply.
