# base58_to_int and int_to_base58 loosely based on base58 gem by Douglas F. Shearer
# https://github.com/dougal/base58

ALPHABET = "123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ".chars
BASE = ALPHABET.size

def base58_to_int(base58_val)
  base58_val.chars
    .reverse_each.with_index
    .reduce(0) do |int_val, (char, index)|
