> Based on CloudTM's implementation.
> The Total Order based commit protocol is a multi-master scheme as currently Two Phase Commit implementation. 
> This protocol relies on the concept of totally ordered delivery of messages which, informally, implies that each node which delivers a set of messages M, delivers them in the same order.
> This protocol comes with two advantages. 
> 1) transactions can be committed in one phase, as they are delivered in the same order by the nodes that receive them.
> 2) it totally avoids deadlocks. 
> The weakness point of this protocol is the fact that its implementation relies on a single thread per node which validates and commit transactions.
