I would like to know what is a correct formal notation for representing a state where the state is defined by

$ K \to (V x N)$

where K is the key, V is the value and N is the infinite ordered set of version numbers. An injective function f takes an element of N and returns the next version number.

  • $\begingroup$ Might be just me, but I'm not really familiar with what you mean by 'state', 'version number' and 'key'? What's the context? $\endgroup$

  • $\begingroup$ like dictionary but with versioned values. f returns the next version number. have it from here hyperledger-fabric.readthedocs.io/en/latest/… $\endgroup$

For formal notation, I'd probably use exactly what the source page uses, just written with standard mathematical typography instead of ASCII: A piece of state is modeled as an element of a mapping $K \to (V \times N)$. (Then explain what $K$, $V$, and $N$ are.)

Is this what you were looking for?
