I can now tell you all: OpenTimestamps did in fact have a small role in the US election! I don't know the full details. But apparently it was used to timestamp election data in Screven County, Georgia; possibly others too.

The total cost for time-stamping at maximum speed for two days, on two calendars: 259,380sats.

If I get more donations, I'll continue to timestamp faster, giving everyone more accurate timestamps: https://geyser.fund/project/opentimestamps
