When you swap the old silkcoin for the new, will you use the same public/private key address space?  I think the best way to swap is to transfer the amount received in the superblock to old silkcoin public addresses.  I think the Syscoin to Syscoin2 swap was done this way.  That way, we can just import the private key using the new wallet/chain without having to send it to a centralized exchange.  I do not like to hold coins on an exchange so keeping them on Polo or sending them to Weaver is not that appealing to me.

The current silkcoin wallet freezes up on me often.  I have tried it on Linux and Windows.  It seems to get worse with every stake reward I get.  Other PoS coins have this same problem but I hope you fixed it with the new version.

This is an interesting project and I will be watching closely.  I have questions about mining your dark version but will wait until after the swap.  I have a small GPU farm (mostly EVGA GeForce GTX 750's but a mix) but don't know if they will be good for your darksilk algorithm.
