Shoot 2021-08-26-071835

These photos were all shot at home over the last few days, except for the Cooper's Hawk photos which were taken at the end of June. They were taken just after dusk with my Nikon P950 on a tripod, and were too noisy to use. I just recently bought DxO PureRAW, and was able to remove the noise with it. The pictures aren't great but I was able to ID the bird as a Cooper's Hawk.

📄 hashes-2021-08-26-071835.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.
