Shoot 2024-03-12-084538

Red-shouldered Hawks have been very active around the house lately. The one in this gallery was quite a ways off but I was able to capture it on a snowy tree, which made for a nice habitat shot.

I returned to a nearby lake to look for a Horned Grebe, and this time I found some! A new county bird for me. I also got some out-of-the-ordinary shots including some Greater Scaups and a group of Double-crested Cormorants flying right at me.

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.
