Public and Private Keys

Public and private keys are an integral part of the Cryptocurrencies that help to make the transaction go smoother and more secure. The Public Key Cryptography makes sure that the users get a secure and private communication channel for the transaction.

When you buy Cryptocurrency, you actually buy the Private Keys that give you access to the amount of Crypto Coins you have bought. And then there is Public Key. It is possible to unlock the Public Key with the Private Key, but it is impossible to access the Private Key with the help of Public Keys.

How the Transactions actually Work?

When you are in the market making payments with the help of the Cryptocurrencies, every Cryptocurrency transaction needs a Private Key for authentication. Only after the authentication, will the transaction be conducted. Having a Private Key shows that you are the owner of the Cryptocurrency. This is all done to make sure that your transaction is safe and secure.

During the time of the transaction, a deal is made called Consensus. It is a proof of work that signifies that you are the owner of the cryptocurrencies that you are using in the trade or in any kind of transaction.
