Shoot 2024-08-28-155026

I went out a couple times, once during some intermittent rain and once just as some fog was lifting. I didn't have any terribly noteworthy bird encounters, but did take some nice shots of a cooperative Turkey Vulture.

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

📄 hashes-2024-08-28-155026.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.
