Cryptocurrencies are almost forgery-proof digital currencies based on blockchain technology. They can be purchased using cryptography or virtual currencies.
Cryptocurrencies represent decentralized networks that utilize blockchain technology and are essentially overseen by a central authority.
This makes cryptocurrencies unique in their function, as they effectively escape the influence of a government or central bank.
These digital currencies rely on encryption techniques used to secure the networks used to authenticate blockchain technology.
Cryptocurrencies can also accept online payments called “tokens.” Tokens are represented in blockchain technology as internal ledger entries, while cryptocurrencies represent cryptographic methods and encryption algorithms.
These include public-private key pairs, various hashing functions, and an elliptic curve.
Each cryptocurrency transaction is logged in a web-based ledger using blockchain technology.
Consequently, they are also approved by a disparate network of individual nodes or computers that maintain a copy of the ledger.
For each new block created, it must first be authenticated and confirmed by each node, making it nearly impossible to falsify the transaction history of cryptocurrencies.
Cryptocurrencies are becoming Mainstream:
In 2009, Bitcoin entered the market, the first blockchain-based cryptocurrency, which has since risen to become the most traded and valued cryptocurrency in the world.
Since then, many other cryptocurrencies have been introduced and gained popularity in recent years. These are referred to as altcoins.
Common examples of these cryptocurrencies include Ethereum, Ripple, Stellar, and Dash, among many others.
Cryptocurrencies also promise a wide range of technological innovations that have yet to be developed.
