A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralised networks based on blockchain technology—a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued or controlled by any central authority, rendering them theoretically immune to government interference.
What is Blockchain
A blockchain is a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. The decentralised database managed by multiple participants is known as Distributed Ledger Technology (DLT).
Which means, if any block of that information is changed, it would be immediately get caught that the block data has been tampered with. If any hacker wants to change the data, he has to tamper each and every data present on the blockchain network, which is quite impossible to do with current resources.
Now, how Blockchain is different from Crypto Currency?
People often get confused between blockchain and cryptocurrency. Crypto currency is the exchangeable digital token we can buy, sell or trade. However, blockchain is the technology behind it.
Types of Crypto Currency
While Bitcoin is the OG Crypto currency we know, but there are several other crypto currencies we can see. There are more than 4000 different crypto currencies are there in the market and new ones are getting added in a daily basis. Now let's discuss, different types of Crypto currencies.
Crypto coins vs. tokens
When discussing cryptos, you may hear the terms "coin" and "token" frequently used. While they may sound like interchangeable terms, there is a difference, and it's important to keep them straight.
A digital coin is created on its own blockchain and acts in much the same way as traditional money. It can be used to store value and as a means of exchange between two parties doing business with each other. Examples of coins include Bitcoin and Litecoin
Tokens, on the other hand, have far more use than just digital money. Tokens are created on top of an existing blockchain and can be used as part of a software application (like to grant access to an app, to verify identity, or to track products moving through a supply chain), or they can even represent digital art (like with NFTs, or "non-fungible tokens," that certify something as unique). There has even been experimentation with using NFTs with physical assets, such as real-life art and real estate. Ether is an example of a token, which is used to make transactions on the Ethereum network.
