I still don't see the point in a 'permissioned blockchain' without proof of work. If you just put Paxos / Raft / any other consensus protocol on top of a 'blockchain', all you're basically doing is reinventing distributed databases.

Tierion uses the Bitcoin blockchain for these reasons. Proof of work is what really secures your data.

Is this a trustless system? If so, what is the game theoretic aspect of it, what nodes do the mining and what are their incentives? If it is not, what prevents you from implementing a traditional distributed system with traditional consensus protocols? I'd wager that traditional methods are much more performant than the BitCoin blockchain in that scenario.
