Shoot 2021-08-09-130608

For the second week in a row, I was able to see a flock of Cedar Waxwings hanging out above the river here. They'd often land on the handrail of the bike path bridge I was standing on, so I was eventually able to take a few good shots of them. I also happened to see a decently-lit Osprey who hung out in a tree for a minute.

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

📄 hashes-2021-08-09-130608.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.
