Briefly, Nucleoid is a runtime environment that allows declarative programming written in ES6 (JavaScript) syntax. Since statements are declarative, the runtime provides logical integrity and persistency, and it is all possible with enabling plasticity in declarative programming.

Here is a simple example:

> a = 1
> b = a + 2
> if(b > 10) { c = true }

In this case, the runtime receives 3 entries as declarative statements, means a in b = a + 2 represents logical intention, not memory location, so that, running a = 10 on the runtime triggers chain event, and as a result, the runtime automatically changes b to 12 and c to true in order to guarantee logical integrity.

> a = 10
> b
12
> c
true

In this paradigm, the behavior of the runtime defined as general purpose declarative runtime and follows formal logic as a default, but still runs as in transactions and does support majority features of database, so any uncaught exceptions or conflicts with formal logic are rolled back by the runtime.
