1. Executable simulation tool for Nxt-like 100% Proof-of-Stake forging(with delays & transactions). Executable
multibranching forging simulation tool(to estimate properties & computational requirements of Transparent Forging).
Some proofs around the code. 1 paper + 5 articles at least.

Estimated duration: 2-4 weeks.
Corresponding lot size: 300,000 Nxt

2. Research on Consensus properties of multibranch forging. In particular, Nothing-At-Stake problem will be formally
defined and analyzed after this milestone.

Estimated duration: 6-8 weeks.  
Corresponding lot size: 400,000 Nxt
