Rankings

Ultimately, quantifying economic complexity is about ranking economies. The problem is that the ECI approach attempts to find the answer recursively based on a set of well defined products that are more or less unchanged, while in a crypto economy the sources of attention change constantly due to the swift pace of innovation — so there is no standardized classification of products as in international trade, and the result could not converge. Also, in the case of countries the relationships are binary (either a country produces a product or not, that is, a link exists in the network or not), while in a crypto economy the strength of the attention signal matters — this is why the boxes in the matrix on Figure 4 are colored with different intensities.
