I sure would like to see some new development with this coin. I had high hopes for it when it came out, followed it for a while, got away from it, checked back in, and it looks the same as it ever was...
If you have some specific ideas or suggestions you could go over to the gitter: https://gitter.im/BlackCoin_Hub
Janko33bd and Vinceblk are both almost always available there.
This bitcointalk thread is fairly ignored.
I went there and it's very active, but I'm not a member and don't feel like joining yet another online doodad that I'm going to forget my password for, but I do have a suggestion that can be passed along if somebody thinks it's worth it. Any bounty for my brilliant scheme would be appreciated...
A long time ago there was an internet service provider called Juno, and you could get free internet if you allowed them to use your dormant, online computer to perform complex mathematical computations, and Juno would find buyers that needed this service, presumably make money, and for letting them use your computer you got free internet. The cumulative power of thousands of computers hooked together made a sort of supercomputer, according to Juno. I've long thought that a proof-of-stake wallet could provide this same kind of functionality and reward the wallet holder with a higher stake payout. I have absolutely no technical ability to make this happen, but always thought it would be a great option for crypto coins.
Just so you know, gitter uses github and twitter accounts, don't have to sign up for anything if you have either of those.
