What is cryptocurrency?

There is no physical form of cryptocurrency like the fiat currencies. It is a digital currency which can be used for seamless, direct and speedy transactions between parties.

How do the cryptocurrencies work?

Cryptocurrencies were developed over the foundation of a cryptographic invention known as blockchain technology. Blockchain supports multiple technologies, including cryptocurrency, without which blockchain would not exist.

Blockchain

Blockchain is a set of blocks made of complex mathematical problem based on cryptographic technology. The computers aim to solve their problems, and when they solve one problem, a block is complete. Whats makes a block unique is that when information inside of a block is changed, the block becomes invalid or broken. The only way to fix the block is to replace the wrong data with the original data.

Mining

Mining is the solving of blockchain to convert into the blockchain. People who solve these problems using computers are called miners. Mining can be very difficult and requires powerful processors to solve the blockchain puzzles. These computers can be costly and require heavy GPUs. For solving these math problems, the miners get rewarded with digital currency.

The miner needs to make sure that the transactions are valid and they do this by ensuring the person they are getting the coins from have enough coins. Miners can examine the existing blockchain or check the wallet of the person they are trading with. Since wallet can be public, it raises a few privacy concerns, but you can have as many wallets as you want. There are also some technologies and currencies that provide complete anonymity.

 

Security

Security is the ultimate concern while dealing with currencies. There are several security measures for cryptocurrencies which are designed to ensure that miners and the complete network are secure. On a personal level, each wallet is highly secured with a private key which only gives access to the owner. The underlying blockchain is also secured against hacking as any alteration in the information of a block can make it invalid. For now, blockchain technology is highly encrypted and secured, which is why it is also used for creating security software.
