What is cryptocurrency ?

This is one of the most frequently asked question out there “what is cryptocurrency ?”.

To make it simple , Cryptocurrency is a digital version of money where the transactions are done online. A cryptocurrency is a medium of exchange just like your normal everyday currencies such as US Dollars ,Rupees but designed for the purpose of exchanging digital information  through a process known as Cryptography.

The first ever-successful cryptocurrency emerged form the inventions of  Bitcoins  by  Satoshi Nakamoto.

This was then followed  by birth of other types of cryptocurrencies competing against the Bitcoin.

How do cryptocurrencies work ?

The reason why cryptocurrencies are in such demand right now because Satoshi Natamoko successfully found a way the decentralized digital cash system.

What is decentralized cash system ?

A decentralized cash systems means the network is powered by its users without having any third party, central authority or middleman controlling it.  Neither the central bank nor the government have power over the system.

The problem with the centralized network in a payment system is the so called  Double spending .

Double spending happens when one entity spends the same amount twice.for example when you purchase things online you have to pay unnecessary expensive transaction fees , usually this is done by a central server , they keeps track of your balances, this is most commonly known as the Blockchain Technology.

Cryptocurrency is derived from the word cryptography . which refers to the condenses keeping process secured by strong cryptography. Blockchain technology functions in managing and maintaining a growing set of data blocks and this is by using the decentralized or known as P2P (peer to peer)network.

In Blockchain once a piece of data is recorded , it can not be edited or changed .

To put it in simpler terms , it enables you to send a gold coin via email.The  P2P network is a consenses network which allows a new payment system and the transactions of new digital money.

Blockchain Technology

A cryptocurrency like Bitcoin consists of its own network of peers. Every peer has a record of the complete history of all transactions as well as the balance of every account.

A transaction includes a process where “A” gives X amount of Bitcoins to “B”and signed by A`s private key after signed the transaction is broadcast to the network, the information is send from one peer to every other peer on a network.

Confirmation is a critical stage in cryptocurrency system.confirmation is everything, when the transaction is not confirmed, it has the possibility of being hacked in forge When the transaction is confirmed , it can not be reversed,and its impossible to be hacked  and its not forcible as it is a part of permanent record of the historical transaction.

The blockchain can be like in to an online ledger where all transactions are recorded and visible to the whole network. This comes to show that cryptocurrencies are not secured by people or trust , but by complex mathematical equations.

It is very secured, and only miners are able to confirm a transaction ,this is the rule in cryptocurrency network ,they record transactions , verify them and disperse the transaction information in the network. For every completed transaction monitered and fascilated by the miners, they are rewarded with the tokens of cryptocurrency for instance with bitcoins . Since miners play a major roles in a cryptocurrency system , Lets look at their role in more details 

What are miners ?

Miners are needed because of the nature of the decentralized network where they have no authority to delegate tasks and the cryptocurrency needs some kinds of system to prevent any form of network abuse.

Anyone can be a miner.

For instance,a person may create thousands of peers and spread  forge transactions , it will disrupt the system immediately.

If you be a miner,you would need to solve a cryptologic puzzle which is a  set of very complex mathematical questions set by Satoshi Nakamoto himself. If you successfully solve the puzzle as a miner,you can added to the blockchain.

The miner is also given permission to add a cryptocurrency transaction to the system which automatically grants him a specific number of bitcoins.  This is the only way to create valid bitcoins,bitcoins can only be generated if a miner can solve a cryptographic puzzle, the level of difficulty increases with the amount of computer power of  the miner invests.


How are the cryptocurrencies value determined ?

The value of cryptocurrencies dependent on the market ,whether price of various cryptocurrencies vary a lot, and this is one of the most fluctuating markets today.

The of cryptocurrencies like any other product is dependent on the demand and supply, if more people demand a particular currencies then the value increases, more units are mined by miners to balance the flow ,however most currencies limits the supply of tokens,for instance the total amount of Bitcoin is 21 million only therefore Bitcoins supply will decreases in time and will reach its final number.


What is Cryptocurrencies used for ?

There are 3 different transactions that can be performed by using cryptocurrency. All transactions are completed  online .
