Introduction to Blockchain
Blockchain is a technology invented with the birth of Bitcoin, the first crypto currency. For decades people have thought of a way to design a digital currency, but to no avail. An obvious necessity of a currency is not to have duplicates: when I give you a dollar, I don’t have it anymore. Digital data does not follow this. If I send you a picture on whatsapp, we both have it, unless I delete it. This is where the blockchain comes in.
