Can you fill the questionnaire? 
Sure.Some corrections.
| Consensus Mechanism | Pure PoS (PoW was only in distribution phase) |
| Worst Case for Confirmation Time | Infinity <-- thats right but can you please elaborate on this category? Its infinity for every blockchain in my definition. |
| Network Security Costs | 1% of expected market cap over a one year time period <-- this is a theoretical maximum, since inflation is 1% of staking coins |
| Mobile Wallet | Yes. Full node: https://github.com/janko33bd/bitcoinj/tree/blackcoinj Lightweight: http://coinomi.com/ |
| Pruning | No active development on that in BlackCoin afaik, however, Gavin Andresen often speaks about it in his blog so it might be implemented in the Bitcoin core and eventually be merged into BlackCoin (in contrast to NXT, BLK is forked from the bitcoin core). |
| Voting System | In development, its the same technology as messaging and will be part of blackshares. |
| Alias System | Considered (not really planned) |
