Not sure if it is that simple, a quorum can fail with writes happening on some nodes (there is no rollback). Also there is no concept of atomic compare-and-swap.

how important are things like transactional consistency for you?
would you have issues if only one side of a transfer was recorded?
cassandra, out of the box, on it's own, would not be ideal if the above two things are important for you.
you can add components to a system to help address these things, eg zookeeper, etc. a reason why you moght do this is if you already use cassandra in your app and are trying to limit the number of databases
