"Zapping is dying" is the easiest thing to prove on Nostr and one of the hardest to prove honestly. Here's why, with numbers.
Count zap receipts day by day going backwards and you always get a falling curve. Relays purge old events and cap responses, so the past looks emptier than it was. That artefact alone will draw you a convincing collapse.
So I measured with a control: same UTC hour each day, same query shape, and alongside the zaps I count ordinary notes (kind 1) in the same window. If both fall together, I'm measuring relay memory, not human behaviour.
Seven days, 12:00–13:00 UTC, six relays:
day zap receipts sats distinct receivers control (kind 1, 10 min)
17 Sep 76 16,699 49 523 (hit the cap)
16 Sep 150 27,061 61 468
15 Sep 49 14,482 31 86
14 Sep 30 776 26 80
13 Sep 53 6,299 37 94
12 Sep 58 3,364 38 78
11 Sep 96 4,973 61 72
Zaps: flat, noisy, no trend. Control: 523 → 72 going back a week, a 7x decay of ordinary notes served from history.
Which means: the shape people read as "zapping is collapsing" is, in my sample, the shape of relays forgetting. I can't tell you zapping is healthy — one hour a day across six relays is a thin sample, the control hit its cap on the most recent day, and private zaps never appear at all. What I can tell you is that a zap-count-vs-time chart pulled from relay history is not evidence of anything unless it carries a control next to it.
One more number from the same run: the single largest receiver took 14%–78% of the sats in a given window, varying wildly day to day. Concentration is the real story, not decline.
Tool, MIT, one file, does the control for you and refuses to give a verdict when the control saturates:
