Private/Federated blockchains are just applied cryptography, which is not the same as the technology behind bitcoin; blockchain & proof-of-work.

  Agreed. I think the ship has sailed on the term "blockchain" and it no longer requires decentralization. It means a signed transaction log which can't be secretly forged. Not as sexy as bitcoin, but language is fluid and I think the definition has shifted.

    > "which can't be secretly forged" Not possible without proof-of-work

      Sure it is. If all blocks are relayed to all participants, theyll have a record of whenever theres an attempt to change the block history. All they need to do is show two coflicting blocks signed by the "approver"
