I think there is nothing at all wrong with more conventional security strategies, like credentials, and sure, obscurity can be a useful tactic.

All I am saying is: what is super special about the BTC blockchain, is that it doesnt rely on those at all, it doesnt need those things, because it has the magical property of security by Proof Of Work.

Removing that and still talking about a Block Chain like its a special thing, makes no sense to me.

Anyways this is all conjecture, its not even clear what they are doing in there. Would love to hear details.

And all I'm saying is it doesn't matter how Bitcoin does it. The problems being solved are different. Bitcoin has to use a stupidly inefficient method of selecting who adds the next block because the participants aren't known. That's it. The proof of work waste adds nothing else to the security of the system except when you don't know the participants. So if you don't have to do that then proof of work adds nothing. You're hung up on proof of work but it seriously sounds like you're over estimating how important it is to the process. The block chain itself has nothing to do with proof of work. Remove proof of work and you have a blockchain. PoW is only for deciding who adds blocks.
