Stdlib.result
Lwt.tbuild specs asynchronously computes (1) an initial state for the ValidationMachine, and (2) the environment associated to this state.
The machine enforces the resulting state is consistent with the specs given as inputs, and raises an Assert_failure exception if it does not. It also enforces that the machines used underneath remain in sync.
One can use the optional argument subsidy to set the subsidy amount to a given value (by default, we use the same as the main chain). Additionally, the invariant optional argument can be used to verify that a given invariant holds at the end of the initialization.

The invariant optional argument can be used to verify that a given invariant holds after each baked block.

The invariant optional argument can be used to verify that a given invariant holds after each baked block.
