The Blockchain

The blockchain technology is made up of a block of “secured transaction data” known as a ledger that cannot be erased, modified, or hacked. It was introduced in 2009 by Satoshi Nakamoto, as the main technology behind Bitcoin, a cryptocurrency launched as a counter reaction to the 2007 financial crisis. In the very near future, in almost everything we do, in nearly every industry — from brick-and-mortar shopping and ecommerce to communications and recruiting — we will use the blockchain.
