What is Blockchain ?

Image
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...

Ethereum 2.0

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...

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...

Cells are the smallest living units ofan organism. All cells have three things in common no matter what type of cell they are. All cells have a cell membrane which separates the inside the cell from its environment; cytoplasm, which is a jelly-like fluid, and DNA which is the cell's genetic material.                                    1. Cell There are two broad categories of cells.  The first category is eukaryotic cells.   They have organelles which include the nucleus and other special parts. Eukaryotic cells are more advanced,complex cells such as those found in plants and animals.  The second category is prokaryotic cells .  They don't have a nucleus or membrane enclosed organelles. They do have genetic material but it's not contained with in a nucleus. Prokaryotic cells are always one celled, or unicellular organisms, such as...
