However, Google Cloud’s blog post shows off one particularly compelling application: Gini Coefficients. This measurement essentially represents whether a blockchain’s coin supply is concentrated among a few addresses or distributed across many different addresses. Higher numbers mean that a coin supply is very concentrated, as shown in this chart from Google Cloud:
The Google Cloud team has made a few interesting observations. In particular, the team has noted that Bitcoin Cash‘s low transaction fees should have made its coin supply highly distributed; however, this has not occurred. The team also comments on Dash, noting that Dash’s coin supply is “remarkably well distributed.”
The team also acknowledges some possible complications. Multiple addresses can, of course, belong to one owner, meaning that any given coin supply may be more concentrated than it appears to be. Additionally, addresses with small balances have been removed from the analysis, while large, centralized exchange addresses have been left in the analysis—both of those decisions introduce biases.
Google Cloud isn’t the first to notice the importance of wealth distribution: the concentration found in various coin supplies has been a recurring news topic for several years. So, although the Gini Coefficient is not a perfect measurement, and although many other possible analyses exist, the implications are very important. As Google Cloud’s blog post explains:
“Studies … tell us that biodiversity … increases ecosystem productivity by supporting more complex community structures. The downward trend of Gini (i.e. higher levels of diversity) for crypto-asset holdings is likely a positive sign for the future health of crypto-economies.”
However, Google Cloud is quite explicitly not jumping to conclusions, and the project team has noted that different types of analyses could produce contradictory results. As such, it is encouraging users to work with the data in other ways. With any luck, crypto statistics will soon be more in-depth and revealing than ever before.
