Shoot 2022-07-27-193849

I made an early morning trip out to the local wildlife area just after sunrise. It was a very warm sunny morning. Several Black Terns were hunting/fishing, and I got a few shots of them. My shutter speed was too slow for the best photo opportunities but I did get a few keepers. A Ring-billed Gull, a new lifer for me, made a quick flyover at one point. As I was headed back to the car a Yellow-headed Blackbird, also a new lifer, flew overhead and briefly hovered in place above me. I'd been looking for this bird the last few outings to this location so it was great to finally see one!

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.
