  • Block stuffing for profit
  • Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol)
  • Theft of gas
  • Unbounded gas consumption
  • Smart contract fails to deliver promised returns, but doesn’t lose value
  • Functional correctness of implementation even if it's not directly impacting user funds
