You can't make Dash into a side-chain, it's immune to that.
Thank Duffield for that!
If Dash would ever pledge submission to the Dark Side of Crypto and become a slave to Blockstream-Core it would be treason of the highest degree in my eyes and I would be out before you could blink.
To hell with Adam Back and his agenda of destruction.
One can only solve so much with cryptography, the rest of the solution will prove to be economic in nature.
