After reading your post. I didn't understand what the graphene really meant.
I went ahead to do a little research on graphene which i will love to share.

• Graphene is an industrial strength software platform for deploying third generation cryptographically secure decentralized ledgers known as block chains.

• Graphene based systems have orders of magnitude better performance than first-generation Bitcoin-derived systems or even the second generation “Bitcoin 2.0” systems that constitute our current closest competitors.

• Graphene based systems go beyond mere “checkbook” style payments to offer a broad range of financial services distinguished by their transparency and inherent incorruptibility.
  -You can see Graphene as a toolkit for real-time blockchains.

@heiditravels, nice post. I learnt alot about the different generations.
