Information and data in distributed and centralized systems can be altered or manipulated by the operators of these systems, so the truth is not guaranteed. We just have to accept that’s how it is. Don’t we?

His concept has demonstrated how we can guarantee the truth through the integrity of the data within a genuinely decentralized system. His concept, which is only now gaining mass awareness, is ideal for changing our systems. This revolutionary system of data and information processing can change the very foundations of our system, but also, leading on from that, our entire social structure.

In essence, Nakamoto combined a number of existing approaches in such a way that the combination creates a guarantee of truth. A core component is computer encryption. But that alone is not enough; a further building block is required: the linking of older data with new, so that a chain of data blocks is formed. Within this chain, the current data always relates to the previous and that in turn of its predecessor. That is the principle of what has come to be well-known as blockchain—a chain of data blocks that are linked to each other.
