How Cryptocurrency Works – Important Things You Need to know

Cryptography saw widespread use during the second world war when messages were encoded using it. The most popular instance of its use was the German Enigma machine which was touted to be unbreakable but was cracked by Alan Turing and greatly contributed to the allied victory.

How does it work?

We are all aware of the centralized banking system that allows us to make transactions, deposit and withdraw money. Cryptocurrency follows a decentralized model and allows for transactions to be made without having to go through an institution. These transactions do not require a name to be associated with them and hence offer anonymity and security.

Right about now, you might start to wonder how transactions occur without the use of a centralized authority. Well, the answer to that is a little complicated but bear with me as I break it down. Cryptocurrencies make use of ledgers called blockchains that contain information in encrypted form, about the amount transacted, sender and the receiver.

Bitcoin and cryptocurrency is here to stay

Digital money is rapidly emerging as the next big thing when it comes to transacting online.

Cryptocurrency was created by an anonymous individual who went by the name Satoshi Nakamoto. It was introduced as a peer to peer electronic cash system that required no central system to keep account of transactions. The concept behind cryptocurrency is one that took many failed attempts to achieve and was at one point seemed to be impossible by many.

The most basic problem faced by any cash related system is double spending. This can be understood with an example; say a person having 10 coins spends the entire amount for a transaction and then attempts to spend more than whats left in the account on another purchase. Typically a centralized bank having all records would decline the second request but what about a decentralized system? This problem was solved by making use of the concept of confirmation. Whenever a transaction occurs online, all miners are sent the details and their ledgers are updated. Once this is confirmed the transaction is permanently added to the blockchain that is maintained by miners across the globe.

Who Are Miners?

Blockchains are stored by people called miners who use high-performance computing machines to break encoded transaction data. Miners are volunteers who are paid a certain number of bitcoins for completing a block of transactions. Once a block of transactions have been completed by a miner, the block is added to the blockchain and the miner is paid a sum of money. Only the first one to decrypt a particular block gets paid, all others start work on the next block as soon as the current block gets added.

As of today the blockchain size has reached about 107 GB and is set to grow as the convenience offered by cryptocurrency becomes known throughout the world.
