LEARNING ABOUT CRYPTOCURRENCIES
It can be overwhelming at first when you’re trying to learn about the technology behind some of the most popular cryptocurrencies being traded on the market today.

It is exponentially more difficult for beginners who are just starting to explore this new decentralized digital economy. That is why one of our primary goals at World Crypto Index is to take our extensive knowledge of the cryptocurrency ecosystem and convert it into plain English via comprehensive, easy-to-understand articles.

You will find that we have taken the time to carefully review each cryptocurrency in full detail so that you will be in a better position to make an informed decision before buying a coin, or you can simply learn about a new technology you’re interested in. In this way, we hope to help those who are just beginning to learn about Bitcoin, altcoins and blockchain technology by making it easy to understand how each part of this new ecosystem works.

HOW CRYPTOCURRENCIES WORK
A cryptocurrency is simply a digital currency that is built on a blockchain which is usually decentralized. This means there is no single person, entity, government or company that has control over the network.

A decentralized blockchain is arguably the most important piece of any functioning cryptocurrency; it’s a secure public ledger containing all of the transactions that have ever been performed on the network.

In a nutshell cryptocurrencies are simply decentralized, digital currency payment networks that operate like a democracy in which all of the users have a say in any major decisions that can potentially affect or improve the network. Decentralized blockchains cannot be controlled or manipulated by any central authority, including governments and financial institutions.

CRYPTOGRAPHY
Another important part of any usable digital currency is cryptography.
Most cryptocurrencies are developed using advanced cryptographic technology, hence their name; which stems from the idea of “cryptographic currencies.”

Cryptography might sound like an intimidating word and a concept that would be difficult to understand, and that is true. However, the only thing the average cryptocurrency enthusiast needs to understand is that this practice is essentially just the execution of advanced techniques that achieve secure communications in the presence of a third party.

When it comes to digital currencies, cryptography consists of building and analyzing mathematical, scientific and physical protocols meant to prevent third parties from reading or interfering with transactions and other sensitive data that is relayed across the network. It accomplished this by applying a complex mixture of of mathematical algorithms, computer science, communication science, electrical engineering and physics.

Bitcoin is the best example of how cryptography can be used to make digital currencies work. Bitcoin’s software utilizes several different forms of cryptography in order to assign public keys to coins on the network, run the Hashcash proof-of-work function using SHA256 and to perform other cryptographic hash functions. In short, cryptography is what makes Bitcoin transactions, wallets and mining possible.

BLOCKCHAIN TECHNOLOGY
The decentralized blockchain technology on which many of today’s biggest cryptocurrency coins are built act as public ledgers where all of the transactions that have been performed within the network are stored for anyone to independently verify. Public ledgers are what make trustless peer-to-peer transactions possible, because the users of that digital currency know that all of the transactions on the network will be confirmed and displayed on the blockchain.

Today, virtually every cryptocurrency operates on a decentralized blockchain. On the blockchain of most cryptocurrencies, miners compete with one-another to confirm transactions on the network.
With Bitcoin, for example, miners take pending transactions (“blocks”) from the blockchain (a chain of blocks) and turn them into complex mathematical puzzles. Then, they compete with one another to solve them. After confirming a transaction, the miner who solved that particular puzzle is rewarded with the currency of the network (for example, BTC).

ANONYMOUS CRYPTOCURRENCIES
While most cryptocurrencies (including Bitcoin) are pseudonymous, there are also some fully anonymous coins. These types of cryptocurrencies work in a similar way as Bitcoin, with the major difference being that users are
