Shoot 2022-03-09-112929

I've had a few good days of birding. On the 5th, I got a new yard bird with photos: Red-shouldered Hawk. The next day, I got a new lifer and yard bird again with photos: Sharp-shinned Hawk. I knew Sharp-shinned Hawks are small but the one I saw was still unexpectedly tiny! I ran inside to grab the camera and luckily I was able to spot it again when it flew up into a tree for a minute. Two days after that, on a birding outing, I got another lifer: Fox Sparrow (Sooty), as well as my best shots yet of a Bewick's Wren.

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.
