Cryptocurrencies is the most popular example of decentralization, it just means no one can control it. No body is in the center that control and monitor the circulation that is happening
- Just for clarification, though the Bitcoin revolution is all about moving towards total decentralization, it does not mean that it and other cryptocurrencies who've followed through will always be decentralized. Some, especially those who have long benefited, are benefiting or would benefit unscrupulously from the past backward trend (centralization) would try to disrupt the network distribution that a decentralized platform's functionality basically is dependent on and try to gain some form of control of the network (towards less or discrediting decentralization). For example, some info have been circulating that XRP's platform and node distribution/participation may be more centralized than decentralized.
Hence, over-all improvements towards decentralization can be viewed as a movement from or a protest against centralization. In my opinion, with all the occurrences of abuses associated with monopoly/control of power by the few with no regard of the ripening of the potential of delegation, the revolution's so much like an overly past due evolution from monarchy to responsible democracy in the political spectrum, if we are to relate the history on global finance with world politics.
