Shoot 2022-05-27-071105

I got three new yard birds: Western Wood-Pewee, and Pacific-slope Flycatcher, and Yellow Warbler. I don't think I'll ever get three new yard birds in the same gallery again!

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.
