Public measurements
Each tick, about every five minutes, the Divergent Variable Gauge publishes a held value and five domain intensities: ground, solar, space, seismic, and atmosphere. The inputs are public feeds.
What this is
One hash per tick
The beacon is SHA-256 of a canonical text for that tick. Anyone with the same row can recompute it. The previous beacon is reported beside it, so the ticks form a chain.
Unknown until measured
A future tick depends on readings that have not been taken. You can commit to a later tick now and check the result when it lands. That is the useful kind of unpredictability.
Keep secrets somewhere else
This entropy is public and reproducible. It is a poor seed for a password, a private key, or anything that has to stay hidden. It is a good pin for public, verifiable uses: a receipt, a raffle, a sigil, a research note.
