About this artifact

A photograph of a black cat.

How it was stored

A normal pay-to-public-key-hash output contains a 20-byte public-key hash. A data uploader can put arbitrary 20-byte chunks in that field instead. To the network it looks like many ordinary-looking outputs, but the “addresses” are fake because nobody knows a private key whose public key hashes to those bytes.
