Is Proof-of-Importance draft published somewhere?
Edit: Do the devs secure the blockchain by harvesting with coins controlled by them?
Also I'd like to know when source code is planned to be released, it would save my time on implementation of PoI model.
1) The devs harvest with their coins and thus add to chain security.
2) First nem core will be released and then the rest. But there is not yet a definite time scale.
