Shoot 2023-05-15-194627

I went out again looking for Blue-gray Gnatcatchers. This time I went to a location where they'd actually been recently seen, and have been in years past. I didn't see any, but got to watch a Western Kingbird, a new lifer, hunt for a few minutes. We're in the middle of a heat wave here so I couldn't stay out as long as I wanted, and I think the birds were also less active than usual. But it was great to see a Kingbird.

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.
