Blockchain economies exist in cyberspace and regular economies exist in geographical space. Cyberspace is inherently different from geographical space. That said, we believe it is not a stretch to assert that a blockchain fits the definition of an economy.
Multi-chains and their native economic agents function similarly to regular (geographically bound) economies and their constituent economic agents. By borrowing established (mental) models we bring about novel ways of thinking about the financial performance of cyberspace economies and their respective native constituents. Microeconomic analysis and macroeconomic analysis are well-established fields that provide research and practices for thinking about financial performance of geographically bound economies and their economic agents.
