No.
We need nodes.
To transmit transactions.
Lite wallet only and must only work on "lightweight" system ... like smartphone.
Yeah, but dont you understand no one that is a casual bitcoin user is going to be a node? nodes should be people that can run a computer 24/7 and have power of computing and so on and so fort, not the average bitcoin user. Bitcoin will fail if most people are encountered with downloading a 20gb and growing file if they download "the official client" which is what people always do.
cal of duty - 22gb
battlefield 3 - 20gb
world of warcraft - alot more
here is 3 examples of where people WOULD download 20 gigabytes purely for maybe 20 hours of game play and for less then $50 of value.
so if people have hundreds or thousands of dollars of value in bitcoin. then it makes sense to run the proper bitcoin-core.
i do laugh at people that complain about the blockchain size but are usually the same people that have atleast 2 games on their system that exceed bitcoins data size.. and would defend their reasoning for thinking its ok to install a game, but not ok to protect their wealth
