Shoot 2023-03-21-084458

This gallery has several days' worth of yard photos, including some decent Golden-crowned Kinglet shots (a good photo of one of these still eludes me!), good photos of a Hermit Thrush, and a new yard bird: Fox Sparrow!

This Fox Sparrow sat still for a several minutes, but not in a great location for photos. It then gave a few quick calls and disappeared. I guess it wasn't interested in the feeders.

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

📄 hashes-2023-03-21-084458.txt.sig

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.
