Shoot 2021-04-25-072643

This was a good outing. I captured four new lifers: Western Meadowlark, Brewer's Blackbird, Greater Yellowlegs, and Cinnamon Teal. At this particular location I wasn't very close to any of these birds, so I'm glad to have been using my superzoom camera.

The above hashes-<date>.txt file contains SHA-256 hashes of all the photos from this shoot. The hashes-<date>.txt.sig is a signature of that hashes file, created with my PGP key. The signature file itself was written to both the Bitcoin Cash and Algorand blockchains, in the OP RETURN and Note fields respectively, using the transactions below. In short, this proves that these photos and the signature both existed at the time the transactions were written to the Bitcoin Cash and Algorand blockchains. This blog post has more details.
