Question: do we currently implement any consensus mechanisms? Do we know where this would fit in to the current code-base?

do we currently implement any consensus mechanisms?

Not that I know of so yeah, we'd have to figure out where where this fits in to the exiting codebase.

Yeah, it's likely near the boarder of ExWire and Blockchain. Blockchain was meant to (and generally still is) the piece that takes blocks and collects them together into a chain. ExWire is the piece which asks for new blocks from the network. Blockchain (I think) is the right place to decide what is the best block based on some rules.
