Shoot 2021-05-25-130922

I made an early morning trip out to a local hilltop where I'd seen some Cedar Waxwings and some blue birds the day before. I was able to get photos of the blue ones, which turned out to be Lazuli Buntings, a new lifer, and I also was lucky enough to see a group of Red Crossbill down at the ground drinking some sprinkler water.

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.
