Individuals and companies have the option to use decentralized digital technologies to manage data flows and usage. This is based on individual freedom and self-determination. These technologies will allow individuals and companies to have dynamic data portability in real time, as well as various compensation models. Modern capitalism was born in the XIVth century when private property rights over production means were established. Today, data ownership rights will be the foundations for a distributed and decentralized new data economy.
