Hyperledger Fabric: Not a Blockchain

I see it as a way for technologists to satisfy non-tech people that "yes, we use blockchain now" when in reality this is just an immutable BFTDL with configurable consensus (perhaps similar to what aircraft have been using for many years).

Full, PoW/PoS blockchain like Bitcoin or Ethereum is hard to justify in an enterprise. Decentralization is rarely part of a viable business model.

BFTDL?

Byzantine Fault Tolerant Distributed Ledger

My advice is to say "yes, all our developers use blockchain-related technologies" and never let on that just means you use git.

Yes it is uses blockchain technology! http://hyperledger-fabric.readthedocs.io/en/release-1.2/bloc...

Rolls Royce uses "car technology" to build airplane engines, but that doesn't make an airplane a car.

So it's a just immutable, distributed linked list of signed nodes with a consensus protocol like two stage commit, paxos, isis and maybe overlay network and peer forwarding to bridge some gaps?

Sounds traditional distributed systems but now with signatures involved.

i can't find a reference to isis, google is pretty swamped with the term.

are you referring to the work by Ken Birman?

Yes, Birman and Joseph.
