Usage Pulse
The chain has no addresses to geolocate — that is the point of Zcash. But every block carries a UTC timestamp, so the daily and weekly rhythm of transactions is public. Line that rhythm up with where the sun is and where the on-ramps are, and a picture of who is transacting when emerges without anyone being identified.
Population-weighted by each country's time-zone centre. At its busiest hour, up to 98% of the world is awake somewhere with open ZEC access. Transactions track that curve more closely than raw wakefulness — consistent with use concentrated where on-ramps exist.
Each dot is one week's busiest UTC hour; the line is the transaction-weighted trailing mean. Seasonal drift of about an hour follows daylight-saving changes in the large western markets.
