Yes that's right. It's all viewable - it's the only physically observable blockchain (that I'm aware of). Also I'm not really sure what a blockchain is, but I'm confident this qualifies.
What plans do you have to present periodic snapshots of the full chain? I'm uncomfortable going all in until I can be sure that my links won't be edited out.
I'm thinking about adding a live Twitch stream of the chain, but that sounds like a lot of work so I'll probably just upload periodic pictures of it in a pile on my floor to Twitter every few days and charge $5,000 if people want to come audit it physically.
