/*
  Todo:
    -Store last scanned blockheight and scan from 720 blocks prior to that (1 days) ((Instead of just scanning 1440 blocks prior to current block))
    -If no recorded scanheight, scan from beginning of blockchain (0)
    -Add feature to log all sends between users & withdrawals.
    -Double check on 3rd confirmation, mark as stale if transaction was not approved.
    -Add faucet
    -Add lottery
    -Add rain command (reward past 5 active users)
    -Spam chat log on October 23rd at 18:23UTC with "Happy birthday uPlexa"
    -Randomly start spraying rewards at people.
