Shoot 2022-10-19-145618

I went to a local park with a duck pond specifically to finally take some shots of Rock Pigeons. It was overcast, which was good for shooting, but I had to use ISO 4000. I got some decent shots but I'd like to try again someday with a bit more light.

📄 hashes-2022-10-19-145618.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.
