What is the Blockchain technology ?
A Blockchain is a digital ledger in which transactions made in cryptocurrency are recorded chronologically and publicly.
A cryptocurrency is a secured digital currency. It basically means that instead of having dollars or euros in your pocket you would have digital tokens which can be used for the same purposes: buy or sell things, back projects etc.
Ether is one of the main cryptocurrencies on the market, there is others as such as Bitcoin, Bitcrystal, Steem and many more.
What is new about it ?
Cryptocurrencies are decentralized. That means that its value is not controlled or influenced by any bank or government. You can’t just print cryptocurrencies, you have to « mine » them. Everybody can do it like every body can mine gold or silver. All the transactions are stored in « blocks » for all the world to see. When a block is closed, another begins, and that’s what’s called the Blockchain.
