Problem Definition

What the blockchain module does and what someone think it might do based on the name has become two different things.

Proposal

The fast sync should be extracted into a different module and the blockchain should consist of just the store of blockchains and the necessary interface (there was some talk of having a switch or some form of supervisor that would operate each of the modules which could also be included in the blockchain module)

This notion was mentioned previously here: #2458
