Is this particular blockchain permissioned in such a way that users couldn't continue operating it outside of Amazon?

  Yes. As far as I can tell it's effectively an immutable ledger, a bit like a Git repository with signed commits. No proof of work or similar.

    It's basically a schema-less database which you could query with SQL-ish syntax (PartiQL) and which provided additional views to let you query the history of changes. Git is a good analogy. I've never used the signing for anything but the ability to query the history makes it trivial to implement things like point in time recovery (essentially equivalent to a git checkout) or audit logs (essentially git blame or git log -p), which would otherwise require a much more complex schema in something like DynamoDB: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-sort-keys.html#bp-sort-keys-version-control https://docs.aws.amazon.com/amazondynamodb/latest/developerg...
