Nice post. Not a bad list at all! While early contenders like those listed above will have an immediate advantage, I also think that once this concept takes hold, next-gen blockchain will be the real winners. The awareness is still so small, that these newcomers that seem unheard of to us, will offer so much more in innovation, speed, security and ease of use... Stay tuned!
do you know of any such a newcomer that has, in your opinion, a great potential for the future
@janci, so far AION, Neblio, and Wanchain are appealing. Current sleeping giants could be Nexus and Bancor, of the top of my head. But like I said, there is a huge opportunity to improve on existing blockchain and additional companies may arise to fill these needs. The difficulty today is sorting through the ICO's to find some truth in the future...
