Chris,

This is a very well thought-out paper!  Two very minor suggested mods for clarity:

“As the shared ledger concept gains tracking traction in the business world, blockchain’s added feature – smart contract – is also getting a lot of attention from the industry.”

“We believe that one of the fundamental requirements for any blockchain fabric is that the identity and patterns of behavior of any party on a network must be impossible can be protected from unauthorized parties to ascertain by inspecting the ledger.”

Cheers,

Duc
