Shoot 2022-03-17-203550

I enjoyed a quiet walk down at the ponds. I finally saw and photographed a new county bird for me, American Goldfinch. I can't believe it took so long to see one of these here. I also finally got a photo of some Cackling Geese. I've seen them in large numbers here and there around town but never with my camera. Also of note was a Bushtit building a nest, which I haven't seen before.

My "birds in review" collages can be found here.

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.
