At AWS re:Invent this week Amazon launch a rake of new services, including a managed blockchain and quantum ledger database (QLDB) service. Their blockchain offers a managed scaleable service and the QLDB ledger offers an append only immutable ledger with a central trust authority. I think these services will be huge for companies that don't want to deploy and manage their own blockchain, or that don't necessarily need the distributed part of DLT.
