These are Byzantine Conditions that are signals for users to exit the Childchain.

invalid_block
Indicates that an invalid block has been added to the chain. A block is considered to be invalid when there is something wrong with a block received by the Childchain. Including a situation where the root hash of the transactions in a block that has been submitted to the root chain does not match with the content of the block found on the Childchain's API. The user should exit.

block_withholding
Indicates that the Childchain is withholding a block whose hash has been published on the root chain and is not available via the Childchain's API. The user should exit.
