I think a case can be made for a system like this that uses "consensus nodes" but at the end of the day this approach leads to something like an amphibious car: It's not the best car, and it's not the best boat.

I think it's better, instead, to use bitcoin for some activities and to use a central payment processor for other activities. The central selling points of Hyperledger are "transaction speed" and "low fees"... Why not just use centralized Bitcoin off-chain transactions for these situations, which are even faster and likely even cheaper?

Usually if you want a transaction to be confirmed in under 10 minutes and for a small fee, you're dealing with a transaction under 100 dollars, in which case trusting a central server that is driving off-chain transactions is not a problem.

EDIT: Reflecting more on this, I think a case can be made for a hyperledger-like system beyond a centralized off-chain mechanism, but the problem it solves is small enough that I couldn't imagine using it in the short term. In the long term, something like this may be useful.
