Taxonomy of centralization in public blockchain systems: A systematic literature review

作者：

Highlights：

• Centralization in blockchains cannot be adequately described using the binary notion.

• Our taxonomy captures 13 aspects of centralization over 6 architectural layers.

• We apply the taxonomy to Bitcoin and Ethereum and present empirical results.

• Empirical results suggest centralization may not always have a negative implication.
