What is Blockchain & Cryptocurrency ?

In one sentence: Cryptocurrency works on Blockchain technology.

Let’s first understand both one by one:

Blockchain Technology

Central to the appeal and functionality of Bitcoin and other cryptocurrencies is blockchain technology. As its name indicates, blockchain is essentially a set of connected blocks or an online ledger. Each block contains a set of transactions that have been independently verified by each member of the network. Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories. The contents of the online ledger must be agreed upon by the entire network of an individual node, or computer maintaining a copy of the ledger.
Blocks have certain storage capacities and, when filled, are closed and linked to the previously filled block, forming a chain of data known as the blockchain. All new information that follows that freshly added block is compiled into a newly formed block that will then also be added to the chain once filled.

As a database, a blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. The innovation with a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party.
Blockchain technology can serve multiple industries, such as supply chain, and processes such as online voting and crowdfunding. Financial institutions such as JPMorgan Chase & Co. (JPM) are testing the use of blockchain technology to lower transaction costs by streamlining payment processing.

Cryptocurrency

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 decentralized 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 by any central authority, rendering them theoretically immune to government interference or manipulation.
They enable secure online payments without the use of third-party intermediaries. "Crypto" refers to the various encryption algorithms and cryptographic techniques that safeguard these entries, such as elliptical curve encryption, public-private key pairs, and hashing functions.
Cryptocurrencies can be mined or purchased from cryptocurrency exchanges.
Not all ecommerce sites allow purchases using cryptocurrencies. In fact, cryptocurrencies, even popular ones like Bitcoin, are hardly used for retail transactions. However, the skyrocketing value of cryptocurrencies has made them popular as trading instruments. To a limited extent, they are also used for cross-border transfers.

Happy Leaning!

This article turned out to be completely true because blockchain is used in every virtual currency, making it more convenient for traders. I also mine cryptocurrency and try to use more convenient and simple methods. I'm talking now about cryptofaucets.site, which allows you to mine virtual currency easily and quickly by doing tasks. I've been playing this for a couple of months now and have been able to accumulate a decent amount of bitcoin. I am focusing on this particular currency because it is more expensive and valuable in the world of cryptocurrency.
