Shoot 2021-08-15-171127

I was lucky enough to see a couple new lifers on this trip to the ponds: a pair of Long-billed Dowitchers and a Western Wood-Pewee, though both of these lifers were a bit far away and hard to see. The same goes for my first photo of a Belted Kingfisher. I am really pleased with how some of these photos turned out after some processing in darktable.

📄 hashes-2021-08-15-171127.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.
