The concept of POS is great, the Dope-wallet works good enough, but it feels a few fixes are needed to improve just the performance.

I myself cant code, so maybe we collect a fund for improvements, i also recommend another coder for some help, Palmdetroit who is working on Philosopherstone, he is experienced in POS and has a Message in his Signature: https://bitcointalk.org/index.php?topic=840951.0

I do not wanna blame devs here in competence, as said i like your work and Dope, just more eyes see more.
