As described, the implementation of Paxos depends on the generation of increasing and globally unique sequence numbers. This section also described a possible implementation. Describe an alternative approach to implementing such sequence numbers.

The solution is simple, efficient and works. Other solutions are equally possible. What is required is that the sequence numbers are unique and monotonically increasing. Another way of achieving this is to form a sequence number from a combination of a timestamp and an identifier uniquely identifying the associated node.
