Blockchain governance is the process through which stakeholders in a blockchain project interact and make decisions. Some blockchains are very centralized and only a few developers or miners can drive changes to the underlying rules. Others are quite de-centralized, where all token holders can vote. This is analogous to world governments that span from monarchies and autocratic regimes to democracies. In general, centralized systems can govern quicker because there are fewer parties, and they are more vulnerable to the abuse of this power.
