The Rhythm of Zcash
Zcash is built to hide whereyou are. But the chain still has a pulse — every block is timestamped, so the network's daily rhythm is public even when its geography isn't. We read that rhythm against where the nodes actually run. The mismatch is the interesting part.
Outer ring = transactions per UTC hour. Inner ring = how much of the node network is in sunlight. The hand marks the live hour — right now near the western Atlantic, with daylight over Americas · S. America · Europe · Africa · Mid-East.
People and plumbing don't live in the same place
A plain sun-clock guesses at users from sunlight alone. We can do better: the timing of activity hints at when people are awake, while the node map shows where the infrastructure physically sits. Lined up, they disagree — and that gap is something no sun overlay can show.
Thick bar: user base inferred from activity timing. Thin bar: where the nodes actually run. The biggest slice of users looks like the Americas, yet the nodes cluster in European datacenters.
Daylight correlation
How tightly hourly activity tracks the share of nodes in daylight. Strongly positive: the network gets busier as it wakes into the sun.
The machine hours
We predict each hour's share of the day assuming people transact in their waking hours, in the timezones where the nodes sit. This shows actual minus predicted. Orange hours are busier than human routine explains — when exchanges, miners and bots that run on machine time leave their mark. Hover any hour for the breakdown.
Seven days, twenty-four hours
brighter → busier · UTCAcross this window the network is busiest near 16:00 UTC and quietest near 02:00 UTC — a 1.58× swing between its loudest and softest hour. When it peaks, the sun sits over the western Atlantic. The timing leans toward a user base in the Americas, while the machines that carry the network mostly live in European datacenters.
A note on what this is and isn't: these are block timestamps, so they show when, never where. Node positions map the infrastructure — frequently datacenters and VPN exits rather than living rooms — and the sun layer is pure astronomy. Put together they sketch a rhythm, not an identity. Nothing here points to a person, and that is the entire point.
