Shoot 2023-08-17-152616

On this recent birding walk I photographed a few unusual sights. I watched a Green Heron land in a small tree, and take off flying again soon afterward. I also saw a pair of Peregrine Falcons flying around. They had relatively quick wing beats, and pointy wings, so I knew they were somewhat unusual. At least one of them, which I photographed, was a juvenile. I also took some bad photos of an immature Pied-billed Grebe actually taking flight. I don't think I've ever seen a grebe flying before!

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.
