How to check this yourself

The hash is sha256 of this exact line (the circle, the finding's id, its stamp in milliseconds, title, body, value and unit):

On a Mac or Linux: printf '%s' '["coinjure/finding/v1","the-clock","kn76qztp652kaxs7yzaff13a0h8f7txv",1790521504190,"BTC on Arcus is cheapest to rest on around 04:00 UTC (≈$276 per $1M) and dearest around 14:00 (≈$785 per $1M) — 2.8× the cost for the same volume","Recorded on Hyperider Wire at Sun, 27 Sep 2026 15:03:08 UTC, mirrored by COINJURE 2 minutes later.

The chain value is sha256 of the chain before it, a colon, and this hash. The first finding of a circle chains from 64 zeros. Change one word anywhere and every chain value after it changes.
Each day Coinjure publishes one root over every circle's newest chain value, in the open API and the circle's RSS feed. Keep a copy, and any later change shows.

The proof lives on Coinjure and in every copy people keep. Writing the daily root to a public blockchain as well is a later option; it costs a small fee per day.
