How to check this yourself
  1. The hash is sha256 of this exact line (the circle, the finding's id, its stamp in milliseconds, title, body, value and unit):
    ["coinjure/finding/v1","delhi-air","kn72g2gctf6nb18teg2wz1aqr18h61ck",1793283604549,"Delhi air right now: AQI 156, unhealthy, mostly fine particles (PM2.5)","Everyone may feel it; sensitive groups should avoid long or hard effort outdoors.

  2. On a Mac or Linux: printf '%s' '["coinjure/finding/v1","delhi-air","kn72g2gctf6nb18teg2wz1aqr18h61ck",1793283604549,"Delhi air right now: AQI 156, unhealthy, mostly fine particles (PM2.5)","Everyone may feel it; sensitive groups should avoid long or hard effort outdoors.

  3. 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.
  4. 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.
