Explaining Cryptocurrency: A Beginner's Explanation to Bitcoin, Ethereum, and More

 

Cryptocurrencies have become mainstream in finance, technology, and even in mainstream media. 

Yet, if you're a complete beginner, it can be overwhelming to learn about them. 

Here is a simple guide to get you started with the basics of cryptocurrencies, majorly Bitcoin, Ethereum, and other notable digital assets.

What Is Cryptocurrency?

Cryptocurrency is a kind of digital or virtual currency that uses cryptography for security. 

In contrast to ordinary currencies, cryptocurrencies work without a central authority in other words, their underlying technology, going by the name blockchain, is a kind of distributed ledger enforced by a network of computers called nodes.

Key Features of Cryptocurrencies:

Decentralized-No control by a central authority, like a bank or government.

Peer-to-Peer Transactions-Payments are made directly between users without intermediaries.

Encryption: It ensures secrecy and safety in transactions through cryptographic security.

Transparent: Transactions take place along with recordings in a ledger, hence proving it to be transparent.

Limited Supply: A lot of cryptocurrencies have the supply capped, hence inflation-resistant.

How does cryptocurrency work?

Cryptocurrency is all about Blockchain. A blockchain is a chain of blocks, where each block has a list of transactions. 

If some transaction occurs, then it gets broadcast to a network of computers. 

The transactions get verified and lumped into a new block added to the chain.

Key Components:

Blockchain: A public ledger that records all the transactions.

Wallet: A digital tool, software, or hardware applied for storing cryptocurrencies.

Public Key: The wallet address which you give to the person sending you funds

Private Key: A secret key that allows you to spend your cryptocurrencies. Keep it safe!

#1 Bitcoin (BTC):

Bitcoin was the first and is the most famous cryptocurrency. 

It was invented by an anonymous person(s) operating under the pseudonym Satoshi Nakamoto in 2009.

Key Concept: Proof of Work-PoW is a consensus mechanism wherein miners solve complex puzzles in order to verify transactions.

#2 Ethereum (ETH):

Ethereum was founded in 2015 by Vitalik Buterin, and it's so much more than a digital currency. 

It is a network of decentralized apps, or dApps it provides smart contracts in other words, self-executing contracts whose terms and rules of engagement are written directly into lines of code.

Purpose: Primarily, Ethereum is about building a decentralized internet, as many call "Web3."

Key Feature: Smart contracts - automating such processes as agreements and transactions.

PoS: A relatively new consensus algorithm that selects validators proportionally to the number of coins they have and are willing to "stake" as collateral. 

#3 Other Notable Cryptocurrencies: 

Litecoin was created in 2011 as a faster, more "lightweight" version of Bitcoin. 

Ripple is focused on cross-border bank payments, fast and cheap. 

Cardano is a smart contract platform, and it is well known for its research-driven approach and its focus on scalability.

Polkadot (DOT): Functionally designed to link multiple blockchains so they can work together in harmony.
