What mainnet actually looks like.

A report goes out when there is a number worth knowing that nobody has published, and it only goes out with the means to check it. That means three things, every time:

• The date is in the title. These numbers describe one moment on a chain that moves. A figure without its date is a claim about today that was true last spring.
• The method is written down before the conclusion. How the sample was drawn, what was counted, what was assumed, and — at length — what the result does not support.
• The data and the script ship with it. Aggregates as CSV under CC BY 4.0, and a dependency-free script you can run against your own endpoint to get your own numbers.

The upgradeability census repeats quarterly. Where a report measures something that changes, the interesting result is rarely the first reading — it is the second one.
