List of Figures
Scatter plot of the number of unique shop categories within a neighborhood versus total inflow volumes of visitors in each neighborhood in Istanbul.
Diversity of consumption (above) and year-on-year economic growth (below) for neighborhoods within the city of Beijing. The diversity of consumption (or the diversity of visitors) predicts up to 50 percent of the variance in year-over-year economic growth for Beijing as well as for US and EU cities. Source: S. K.

Summary of the creation metadata and registry metadata, where (a) the full creation metadata is placed in the decentralized replicated repositories and (b) a shorter registry metadata is recorded on the ledger, with a link (or hash) pointing to the full creation metadata permitting future verifications of the authenticity of the creation metadata.
Replicated metadata repositories with linked keywords and tags indexing.
Summary of parts of (a) the creation metadata and (b) the registry metadata, where separate index/search databases (c) may be created and where the actual sound recording files are placed into protected storage (d).

Number of weekly active wallets and transaction volume.
Analysis of Ethereum network dynamics for a two-year period from February 2016 to June 2018. The network nodes are wallets, and edges are formed by buy and sell transactions. The outgoing degree of a node reflects the number of unique wallets receiving tradable securities (tokens) from that node, and vice versa for the incoming degree. Both outgoing and incoming degrees have a power-law distribution, similar to what was demonstrated in the analysis of mobile phone, citation data, and many other real-world networks (see, e.g., M. E. Newman, The Structure and Function of Complex Networks, SIAM Review 45, no. 2 (2003): 167256).
