In this fast moving digital world, currency has also taken digital form and this digital currency itself is called cryptocurrency like bitcoin whose name many people must have heard. Crypto currency is the virtual currency which was introduced in 2009 and the first crypto currency was the most popular bitcoin. Crypto currency is not like a note or coins. So we can't take in hands as a rupee or coins and can't put on the pocket. So we can also call this online currency because it exists only online.

The currency of any country, whether dollar, euro or whatever, is completely controlled by their government, but in the case of cryptocurrency, there is no control of any company or government or any agency. That is, crypto currency does not follow the traditional banking system. just can be sent from one digital wallet to another. it is not only bitcoin cryptocurrency but more than 5000 crypto currency. One of them most popular crypto currency are Ethereum, Ripple, litcoin etc. It is the difference thing now the most popular crypto currency is Bitcoin.

Cryptocurrency is slowly coming into circulation in India because cryptocurrency was bane in india by RBI but now RBI has removed the bane. Now crypto currency became legal on india. The second reason why cryptocurrency is not popular in India as compared to other countries. Most of the people of India have a concept that if you want to invest, then FD should be done in mutual funds and gold only Which is not wrong, but investing in this new currency of the new era has different advantages, as in it we can do transactions easily and quickly. International transactions can also be completed in a pinch and we also have to pay negligible transaction fees, there is no middleman in it and the transaction is very secure.

Cryptography is made up of two words- one is crypto which means secret and second is graphy which means to write or manuscript. protecting information and communication through the use of code so that only those for whom the information is istended can read and process it. This method is called cryptography.

More generally cryptography is about consting and analyzing protocols that prevent third parties or the public from reading private messages. This is better to send private message to anyone. When we send the message or anything which is simple so everyone can read but if we will encrypt file or message then that person is able to read message who knows the key.

Types of cryptography

(1.) Symmetric Cryptography:-

It is the simplest kind of encryption technique that involves only one key to encrypt and decrypt information. We can also say it secret key Cryptography.

(2.) Asymmetric Cryptography:-

It uses two pairs of keys used for encryption and description. It is also called public Cryptography.
There are two keys in asymmetric Cryptography:-

(a.) Public key:- this key is known to everyone for encrypting message or file.

(b.) Private key:- This key is known only to that particular person. whom we send messages

How does it make crypto currency secure

The work of cryptography is encryption with high security in really cryptocurrency can not success without cryptography. There are two types of key in cryptography whom cryptography could secure. no-one can steal our cryptocurrency, this is possible cause of private keys. Public and private keys are used in any cryptocurrency transaction, such that the cryptocurrency remains secure.

Conclusion

Cryptocurrency is a digital currency. User of this currency is increasing day by day. The day is not far when every person in the world will start using it and will be the first to know about it. There is no security of cryptocurrency without cryptography. Two people can talk secretly cause of cryptography. I came to know many thing after exploring steem genesis block.
Thanks @awesononso for this knowledgeable lecture.
