Blockchain, cryptocurrencies, Bitcoin, Ethereum…those are major buzzwords of these recent years. Unless you have no access to the internet, it’s safe to say you’ve probably heard of these terms. But what is it, really? And how does it affect how we live our lives in the future? 

Basically, the blockchain is information stored across personal computers all over the world. The information is stored in something called blocks, and they’re connected by chains, hence the name “blockchain”. The system of all these connected computers is decentralized (so that not one person or institution controls it). The information is protected through cryptography technology.

The information stored in these blocks are information of transactions: verified, permanently recorded, and linked according to chronological order.
