Making sense of bitcoin, cryptocurrency, and blockchain:

Bitcoin is now the talk of every table. Recently, it crossed the 50 thousand dollar barrier. Many people use to think of it as a bubble that will burst anytime soon. It was in 2017 when bitcoin was reported on around 15 thousand dollars. 10 years before that, it was a couple of hundreds.

Bitcoin, at this moment, is the most dominating cryptocurrency. Unlike all the other traditional currencies, it does not hold any physical shape, coin, or paper. Everything is digital, based on numbers and algorithms. Hence, no central authorities or banking agencies are controlling it.

 Moreover, there is a ledger that controls all the programming and track of cryptocurrencies called a blockchain. So, when you hear someone claiming to own a coin means that they have bought a coin. If you have little or no knowledge about cryptocurrency, bitcoin, and blockchain, you are in for a treat. Continue reading this article to know everything about it.

What is cryptocurrency:

It is a form of digital cash that can be used to exchange items. One important and significant feature is that it is not regulated by any bank. So, it is centralized and international, there is no duty or tax to exchange it.

There are many similarities as well as differences between crypto and normal money that we hold in our banks. Most of the people are only familiarized with bitcoin, Ethereum, or Doge because of their popularity. However, in general, there are 4000+ cryptocurrencies available. Not all of them worth thousands though.

How does it work:

Cryptocurrency works based on blockchain technology. A data is created based on the previous block and added to the chain, that is how blockchain works. We will talk about it in detail too. cryptocurrencies work on this technology, using the data and records the transaction of each coin.

Let us say if someone has 100 coins, he can only store it in a digital wallet i.e., cryptocurrency apps like Binance. Only that person has the password to that app. Hence, he can transfer or cash out the coin.

If he deals to transfer few coins and buy something in return. The user will have to transfer the coins into his digital wallet before. There are different ways of transferring depending upon the app you use.

The transaction record is kept by signing in form of providing the key before sending. It is verified from both sides via the app.

The record is added to the blockchain to keep a history.

  • Fossil use:

What is blockchain:

For understanding blockchain, let’s break it down into simple forms. When you say blockchain, something strikes the mind that it has something related to blocks and chains. You are right at some point. This technology works as few blocks connecting to the previous ones in a manner that a chain is formed. Although, the new ones are relevant to the previous ones to attach. “The Hash” is like the basic atom of a blockchain block.

So, when there is a change in block, hash changes. Hence, if someone messes or changes a block, they change its hash and hence the previous block gets the signal. In that way, the person who owns the previous version gets notified or it is saved in the memory.

This manner is a great way of making cryptocurrency more reliable and trustworthy. Proof-of-work is also another level of security for it because obviously, you can not just rely on one.

Another part is the explanation of blockchain is the peer-to-peer (p2p) network. This means that instead of changing the whole hash, one person can transfer it to another.

How useful blockchain technology is:

We have already talked and discussed how useful it is for the whole idea of cryptocurrency. Now, let us talk about non-crypto uses of blockchain technology:
