Yes, this is exactly the point by the prize. The question is to show
how something like this could happen spontaneously.

It requires violating local thermodynamic equilibrium. I'm working on an
article and a few presentations for upcoming conferences where I explain
this in detail. This then proves that none of the current models for
prebiotic chemistry can explain the origin of life. A viable scenario is
to get to a large random organic structure forged in an interstellar ice
grain, where organic molecules at low temperatures under UV irradiation
will only interact with nearest neighbors. Thermodynamic equilibrium is
never reached, the system moves farther and farther away from this as
the reactions under UV radiation continue. This way one gets to large
so-called percolation clusters of organic molecules that have a random
structure.
Such random organic structures look totally useless to explain the
origin of life, because what you want are the very specific molecules
that are involved in the biochemical processes in living organisms.
However, the structure of these random organic molecules is such that it
has interior structures with compartments containing large random
polymers and random interior surface structures. These can then serve as
micro-environments within which prebiotic chemistry under normal local
thermodynamic equilibrium conditions can work. With a finite number of N
structures in a compartment one will break symmetries such as chiral
symmetry at a level of 1/sqrt(N). Small molecules can escape the
compartments via pores in the random structure while large molecules get
trapped inside.

"What You Must Do to Win The Prize
You must arrange for a digital communication system to emerge or
self-evolve without "cheating." The diagram below describes the
system.
Without explicitly designing the system, your experiment must
generate
an encoder that sends digital code to a decoder. Your system needs to
transmit at least five bits of information. (In other words it has to
be
able to represent 32 states. The genetic code supports 64.) "
