UTXO tokens on Ethereum

Suppose we wish to model a UTXO system on the EVM. We need to represent UTXO tokens such that all value is preserved when tokens are spent. Note: For this example, we are not concerned about the security of the system and are satisfied with giving authorities the power to create tokens (e.g. as in a plasma system).

Consider the following object:

{
  owner: <address>,
  value: <uint>,

FILE SPACING:
# double space a file
sed G
# double space a file which already has blank lines in it. Output file
# should contain no more than one blank line between lines of text.
