Hi YongJoon,
Thanks for your review on the IPWAVE PS draft.

I modified the text about the blockchain for vehicular networks according
to your comments:
-------------------------------------------------------------------------------------------------------------------------
Each message from a vehicle can be treated as a transaction and the
neighboring vehicles
can play the role of peers in a consensus method of a blockchain
[Bitcoin][Vehicular-BlockChain].
For a blockchain's efficient consensus in vehicular networks having fast
moving vehicles,
a new consensus algorithm needs to be developed or an existing consensus
algorithm needs
to be enhanced.
-------------------------------------------------------------------------------------------------------------------------

I attach the revised draft having this update.

Best Regards,
Paul
