Shoot 2023-04-30-182909

During some early-morning backyard birding, while many birds in the area were singing, I heard a distinct, different call. The Merlin app's "Sound ID" feature identified it as a Purple Finch song. That would have been a new yard bird, so I looked around in the trees but didn't see one. The bird didn't sing again to help confirm its presence. But after a few minutes a brown finch visited one of our feeders. In reviewing the photos later, it looks good to ID as a female Purple Finch. I'm guessing then there was a male-female pair in the yard.

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.
