Shoot 2022-06-21-095059

This gallery has some photos from a walk in the woods near home, where I saw a group of Hairy Woodpeckers, and from another birding outing at Odell Lake where I saw my first American Dipper. I had a great time watching the Dipper. It was very skilled at snatching invertabrates from a fast-moving stream and smacking them on a log to get at the edible parts.

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.
