Blockchains are incredibly popular nowadays. But what is a blockchain? How do they work, what problems do they solve and how can they be used?  Like the name indicates, a blockchain is a chain of blocks that contains information. This technique was originally described in 1991 by a group of researchers and was originally intended to timestamp digital documents so that it’s not possible to backdate them or to tamper with them. Almost like a notary. However it went by mostly unused until it was adapted by Satoshi Nakamoto in 2009 to create the digital cryptocurrency Bitcoin.  A blockchain is a distributed ledger that is completely open to anyone. They have an interesting property: once some data has been recorded inside a blockchain, it becomes very difficult to change it.  So how does that work?  Well, let’s take a closer look at a block. Each block contains some data, the hash of the block and the hash of the previous block. The data that is stored inside...

Even if you are someone relatively unfamiliar with the crypto ecosystem, you’ve probably heard of Ethereum. It is the most famous cryptocurrency after Bitcoin, Ethereum forever changed the use cases of the blockchain. From an open ledger to facilitate only peer-to-peer transfers of money, the blockchain became a platform upon which smart contracts and decentralized applications, the famous DAPPS, could be built.  After all, the much expected Ethereum 2.0 is scheduled to launch this year. But more on that later, in our Ethereum analysis, where we answer the question: What is Ethereum? “A global, open-source platform for decentralised applications”. That’s the one-line description on ethereum.org. With thousands of games, decentralised exchanges and finance apps running on top of the Ethereum blockchain, not to mention tokens, it’s right on point.  This extended functionality for the bloc...

What on earth is Ethereum ?  I mean, I keep hearing about it all the time, I’ve seen it’s the second largest cryptocurrency around but I just can’t seem to wrap my head around it.  Is it as revolutionary as Bitcoin? Can it actually change the world as we know it?  If you want to have a better understanding of Ethereum, but are tired of explanations that sound like complete technical gibberish, stick around cuz' today i will clarify you about Ethereum.  Ethereum was first proposed in late 2013 and then brought to life in 2014 by Vitalik Buterin who at the time was the co-founder of Bitcoin Magazine. Ethereum is the Do It Yourself platform for decentralized programs also known as Dapps - decentralized apps . If you want to create a decentralized program that no single person controls, not even you even though you wrote it, all you have to do is learn the Ethereum programming language called Solidity and begin coding .  The Ethereum plat...

Say there’s a coin that’s currently worth hundreds of U.S. dollars, but it’s not made of gold, or platinum, or any precious metal. In fact, it’s not the kind of coin you can hold in your hand or stick in a piggy bank. It’s a digital currency, which means it only exists electronically. I’m talking about bitcoin .                                                              Bitcoin Bitcoin doesn’t work like most money. It isn’t attached to a state or government,so it doesn’t have a central issuing authority or regulatory body. Basically, that means there’s no organization deciding when to make more bitcoins, figuring out how many to produce, keeping track of where they are, or investigating fraud. So how does bitcoin work as a currency, or have any value at all? Well, bitcoin wouldn’t exist without a whole network of people ...
