If a bitcoin transaction's outputs have a locking script that is basically unsolvable, are the bitcoins lost, or can the transaction be invalidated? (Or something else?)

  • If you are trying to do this on purpose, just set the scriptPubKey to OP_RETURN and nothing else. This makes the transaction provably unspendable: en.bitcoin.it/wiki/…

If it made it into the blockchain, meaning 1 confirmation or more, it practically can't be invalidated. The same feature prevents people from reversing payments.

If it's provably unsolvable, then there's no way to spend the coins, and they're practically destroyed.
