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>,

mminer

import Foundation

func format(bytes: Double) -> String {
    guard bytes > 0 else {
        return "0 bytes"
    }

    // Adapted from http://stackoverflow.com/a/18650828
    let suffixes = ["bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB"]
    let k: Double = 1000
