Blockchain - The Game Changer

Blockchain - The Game Changer

The Presentation I gave for the biggest annual developer conference in Plovdiv - PlovDev (http://2018.plovdev.com/).

In this presentation, we cover how Blockchain works by starting from the ground up and thinking about how we can implement our own decentralized currency. By incrementally solving the problems that occur, we implement the concepts in Blockchain step by step.
