An introduction to Bitcoin makes it sound so user-friendly and a simpleton business, but elegant with modern encryption, but the actual system design is largely kept a secret like a Death Star. It doesn’t matter how a 100 km-wide space station roams around in space freely and shoot out a laser beam that will utterly destroy 12,500 km-wide planet; what mattered was that it destroys planets and can be stopped by a “one-man starship”. Considering how we even got a good prequel out of that story alone, the story behind Bitcoin also deserves some attention with its ever-increasing exchange rate.
