What about a decentralized cryptocurrency (like bitcoin) but instead
of the blockchain having transactions recorded on it, it could have
something lighter... like a list of coins IDs ("cents", actually) and
their owners, like:
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)
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?
