A non-compliant tx will cause it to fail, but you still pay for the effort. I assume things that are on the tx context, e.g. input TxOs and valid time range, can be checked without running a script validator and thus are "free" to invalidate. I don't know how builtin extrinsics like transfers and staking fit in though. Those cost fees. | |

I think that in the case were we want to spend a UTxO that was already spent the validator node will not run the contract script but will reject the transaction right away without any heavy computation. And you are right that usually a transaction is validated off-chain if the user is not malicious. What if somebody would construct invalid transactions on purpose and make the validator node run a complex script that would consume much resources and fail in the end? | |
