"""
Simulation with lottery in shuffled linear ip space

- random hash (not questioned) - sha256 of a bitstring - 32 bytes
- first 4 bytes of hash are converted to an int.
- ip is converted to a 4 bytes int as well
- first 2 bytes of ip are shuffled via a pseudo random lookup table, fed from the hash, to account for non uniform density in public ip v4
- closest eligible ip is voted for

Many draws on a single "nodes" file, to analyse odds and bias.
