If you've been wondering who invented blockchain, you're not alone. In 2008, a mysterious figure known as Satoshi Nakamoto uploaded the blockchain source code to a website called SourceForge. This allowed software developers to collaborate on the project. By January 2009, the first modern blockchain launched with Bitcoin. Initially, Bitcoin seemed doomed to share the same fate as its predecessor, DigiCash. It took two years before it reached the symbolic value of one U.S. dollar, but by 2017, Bitcoin's value had climbed above a thousand euros. Its volatility has remained strong, but the overall trend is upward.
