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...
