A transaction would simply change the owner of the cents and not create any message in the database. Change the owner by changing the values (owner) of the keys (cents) being transferred.

Blockchains work by making the entire history available to be verified and computed against. This is entirely its selling point.
So no, a block chain can never be fixed sized.

After all, how do you know that X owns the coin and not just some random node trying to corrupt and steal every bodies coins?
